Achieving process optimization through simulation

Force IcebergProcess optimization links all the machining operations end-to-end to evaluate and improve the entire manufacturing process. Each step along the way, through engineering, design, CAM programming and machining and up to the final quality and inspection phase, can and should be optimized. Simulation ensures programs are error free and all operations work together as intended, but optimization ensures the whole process is operating as efficiently as possible to save time and money.

As machining gets more complex and customers expect more for less there is room for improvement in any manufacturing process. These improvements, which are not just about reducing costs, might include reduced NC program runtimes, increased throughput, making parts cheaper or getting a product from start to finish and out to market faster.

There are some very significant warning signs that will indicate when process optimization is clearly a must in a manufacturing business – missing delivery dates? Losing out on bids or not as competitive as rivals? Lost contracts and unsatisfied customers? Or declining profits?

Every level of the manufacturing process that a job goes through requires careful planning and communication and the aim of manufacturing is to make it through each step as quickly and efficiently as possible, with the least cost incurred.

In a typical manufacturing workflow VERICUT resides between CAM programming and machine set up.

Manufacturing workflow with VERICUT

Typical Manufacturing WorkflowCAM programmers know that modern machines move so fast it’s pretty much impossible to stop them before a crash occurs. VERICUT CNC simulation and verification software does a superior job at finding problems lurking in NC programs and warning of unexpected machine behaviour, even those occurring between multiple setups. It lets programmers resolve these issues before they reach the shop floor, crash the machine and waste valuable machine time.

With VERICUT the shopfloor can be confident that programs will run correctly. Verification will show if there are any errors or any areas that can’t be reached by the machine or the tools due to fixturing interference. Machinists don’t have to worry about crashes and they don’t have to waste time proving out because it’s already been done between the VERICUT and programming stages.

Having access to the free VERICUT reviewer at the machine tool to check the simulation against reality at anytime is a huge benefit to both shop floor and programmers as it avoids the “what happens next” disturbances during one off or first off production.

There’s also a positive ripple effect for other departments that coordinate with programming. Engineering and design can learn through verification if parts can be manufactured or if changes need to be made before metal cutting. Planning and scheduling will have more accurate cycle times and they won’t have to schedule prove-out times on the machines. The quality control and inspection team can expect higher levels of conformance and fewer issues which makes it easier to approve parts and get them delivered.

These are all areas where VERICUT is helping save time and money.

Silent Killers of NC manufacturing

But there are also the hidden issues, inefficiencies and missed opportunities to optimize processes that erode profit margins. Things like poor cutting methods, non-optimal feedrates in new and existing NC programs, over or under utilizing cutters and/or machine tools, all of which can be draining money with every part made. Some companies work really hard and very diligently optimizing programs but there are opportunities and savings to be had for all machine shops.

This is where Force and Force analysis charts come in.

Force Analysis and Charts

Force Fill ComparisonVERICUT Force recalculates feedrates to maintain ideal constant chip thickness while simultaneously reducing feedrates when needed to maintain safe cutting forces and spindle power, and it does this for each tool. Force is based on calculations and proven cutting data that’s been gathered from tooling manufacturers, material specifications and dyno testing.

It uses very specific cutting parameters, takes into consideration what kind of material is being used, as well as tool type and geometry. It couples this with the cutting conditions that VERICUT collects to give the best data that can be used to analyse and optimize the NC program.

Force charts visualize what’s happening during the machining process and expose areas of opportunity that exist in each NC program, such as erratic chip thickness, chip thinning and inefficient CAM paths that can all be resolved by optimizing feedrates. The charts also show areas of concern, for instance where the force exceeds what the tool capable of, such as excessive cutting conditions or potential for chatter, broken/chipped cutters or damage to part of the machine. In these instances VERICUT Force will lower the federate to keep the force under the limit that of the tools capability.

The impact of optimizing is dramatic, including reduced machining time and longer tool life, which will help the shopfloor by giving more machine capacity and maybe even postponing the purchase a new expensive machine. There will be less post machine clean up because produced parts will be better quality saving even more time per part. Programmers are going to benefit from having correct speeds and feeds information to achieve consistent machining results. All these positives reach all the way back to the quoting and estimating and mean manufacturers can be more aggressive and competitive with schedules and bids.

Simulating, verifying and optimizing simultaneously with VERICUT Force equates to a cumulative effect on process optimization resulting in significant time and money savings.

CGTech Announces 3DLive™ GDML Interface for VERICUT® Software

Irvine, CA– CGTech has announced that its VERICUT software can now read in Geometry Description Markup Language (GDML) files with a new 3DLive Interface. GDML is an application independent geometry description format based on XML.

3DLive is available in MachiningCloud for products that require kinematics such as Machine Tools and Workholding devices. MachiningCloud has traditionally been known for the ability to provide 3D models of cutting tools for use in VERICUT and other related CAD/CAM and simulation software. DMG MORI, HAAS Automation, Mazak, Kennametal and KURT Workholding are among the first to supply GDML machine tool, driven turret units and fixture models to MachiningCloud.

VERICUT is the first software of its kind to support the import of 3DLive files for use in verifying, simulating and optimizing NC programs. This enhancement provides VERICUT users the ability to read in 3DLive data for CNC machines, workholding fixtures and cutting tool holders for use in simulations. This eliminates having to measure and model the components by traditional means or request 3D models from the machine tool builder.

“What has traditionally been a challenging and time-consuming procedure to obtain machine specific information and manually build digital twin machines, can now be done quickly and easily in VERICUT using the new 3DLive interface to read information-rich geometry data,” says Gene Granata, VERICUT Product Manager.

The 3DLive catalog in MachiningCloud currently contains over 8,700 products. 3DLive files contain kinematics, travel limits, minimum and maximum feed rates, initial machine location and 3D geometry colors in a single file format. This data can be read into VERICUT in a matter of seconds. 3DLive fixtures can be utilized to exactly represent the workholding setup in a VERICUT simulation. These fixture models sometimes contain axis movement (I.e. vise models that open/close). Additionally, 3DLive tool assembly holders can be read into VERICUT’s Tool Manager.

CGTech offers a commercial FORCE

CGTech offers a commercial FORCE

The sharp downturn in travel caused by the global COVID-19 pandemic has resulted in the grounding of many aircraft and the largest contraction in the commercial aerospace sector’s history, with most airlines around the world scaling back or cancelling orders. However, seen in the right context, the current challenges faced by the aerospace industry offer opportunities for commercial OEMs and suppliers to make needed changes. This is where the complete digital NC simulation and optimisation software solution offered by VERICUT can help.

According to a recent report by Glenn Brady, Global Aerospace & Defence Leader, and Partner at PwC in America: “The next six to 12 months are a critical period in which to prepare for the recovery. Rather than simply focusing on cuts, we believe that OEMs and large suppliers should also make needed investments in the future, in five key areas: using technology as an accelerator, stabilising the supply chain, streamlining the workforce, focusing on sustainability and making a co-ordinated pitch for government support.”

His report concludes: “The coronavirus has had a devastating impact on the commercial aerospace industry, but it can also be a catalyst for needed change. When the recovery finally comes, the winners will be those businesses that capitalised on this window and took the steps necessary to emerge stronger from the crisis.”


Technology as an accelerator

The use of the digital twin and applying the digital environment to the manufacturing industry is becoming more critical than ever to access commercial business benefits. It will not only ensure that the industry will continue to operate and grow, but also that jobs within the industry are retained, further industry investment is made, and a sustainably reduced carbon footprint can be achieved.

Dedicated to supporting aerospace and other advanced manufacturers in improving processes, CGTech is the original CNC ‘Digital Twin’ developer with their VERICUT software. Using a digital environment with a range of innovative solutions, VERICUT combines the real world with the digital world to ensure manufacturer’s processes are detailed, safe and efficient.

VERICUT uses the CNC digital twin to provide accurate in process simulation, verification and optimisation of a true post processed NC file. The digital twin gives instant feedback on any errors or collisions and provides in-process cutting data. The product portfolio is further supported with the additions of VERICUT Composites and VERICUT Drilling and Fastening – both commonly used within the aerospace sector.

Technical Director, Gavin Powell, says: “With most already using advanced manufacturing technologies and equipment, many commercial aerospace companies still have the opportunity to apply digital techniques to unlock more value. OEMs and major suppliers should invest in digital throughout their organisation such as upgrading how new aircraft are designed and developed. Digital tools such as VERICUT can dramatically accelerate the development process ensuring components can be produced efficiently and reliably. This makes organisations more agile and responsive when dealing with dramatic changes in order volumes.”

“In addition, any digital investment will capture better data allowing the Commercial, Financial and Managing Director to derive clear insights from it, leading to better decision making. So, the case for making digital investments is clear and we believe the global application of VERICUT along with its FORCE module within the aerospace industry speaks volumes about the commercial benefits available.”

FORCE is a software module within VERICUT that uses a physics-based optimisation method to determine the maximum reliable feed rate for a given cutting condition based on four factors. They are force on the cutter, spindle power, maximum chip thickness, and maximum allowable feed rate. Force calculates ideal feed rates by analysing tool geometry and parameters, material properties of the stock and cutting tool, detailed cutting tool edge geometry, and of course VERICUT cut-by-cut contact conditions.


Commercial benefits

Force excels in difficult to machine materials, especially complex multi-axis cuts such as 5-axis flank milling. Whilst the calculations undertaken within the FORCE module are complex, the commercial benefits are straightforward and easy to measure.

UK Sale Engineer, Scott Ravenscroft, explains: “Using the digital twin to simulate every important part of the CNC machine tool VERICUT covers the obvious and visible production concerns, such as crashes, scrap, gouges and prove outs. However, FORCE addresses the hidden opportunities for cost savings, such as inefficient programming and suboptimal feedrates caused by the CAM system’s inability to adjust cutting feedrates for varying cutting conditions.”

Using the football analogy of ‘attack’ and ‘defence’ he highlights how the software achieves its goals: “In attack - we create optimal cutting conditions by maximising chip thickness and keeping the chip thickness constant. Defence comes from setting limits to prevent failure, such as maximum feedrate, cutting force and deflection. All of which are done without altering the trajectory or path of the cutting tool.”

Any business can access the commercial benefits available from VERICUT FORCE. The software relies on proven technology to maximise program efficiency and productivity and typically achieves savings of 8 – 15% on aluminium and more than 15% on difficult to cut materials. Return on investment can often be as little as one production component, with the opportunity to analyse cutting conditions, improve tool life, protect CNC machine tools and reduce operational costs.

This example of a typical aerospace component, an aircraft pylon produced from a titanium forging, has been FORCE optimised. The original cycle time for this component was 2 hours 47 minutes and the FORCE optimised cycle time dropped to 2 hours 12 minutes, a reduction of around 21%. Based on 500 parts charged at £100 per hour machine time, the optimised cycle would offer a £29,000 cost reduction over the batch.

And, FORCE is not only effective on exotic materials, as this example of an aerospace component that has been manufactured from aluminium billet shows. The original cycle time was 39 minutes and the optimised cycle reduced this by 17% to 32 minutes.

“Businesses don’t need to fully understand how FORCE works to apply it, CGTech has a global technical team that can help any company unleash its commercial benefits. We know the savings the software offers are measurable and robust, so the results are sustainable. Cycle time savings of around 20% should not to be ignored. If your machine shop has say ten machine tools running these parts using FORCE optimisation, then two of the machines are now potentially operating for zero cost. How the gains are applied to the bottom line of the business is an internal commercial decision, but with year-on-year cost down pressures across the industry, having such an opportunity to make these savings should be a ‘no brainer’,” Gavin Powell explains.

He concludes: “The industry finds itself in strange and unprecedented times. It is critical that manufacturers embrace new methods, strategies and technology to ensure that processes are secure and stable. This will reduce scrap and waste, as well as increase profitability and capacity. Digital data applications can improve performance internally by showing clearly what is happening in areas such as operations, production and assembly. The array of applications is wide and varied, but VERICUT and, more recently, FORCE, have proven track records of providing commercial success for aerospace businesses around the world. If you want your company to exceed its Key Performance Indicators (KPI) you need to talk to CGTech.”

JEC WORLDFrom the 3 to 5 March 2020, Paris Nord Villepinte exhibition centre in France will become the focal point for the global composites industry with over 1,300 exhibitors demonstrating the very latest engineering and technological innovations at JEC World. At this year’s international composites trade show CGTech, developers of the world’s most advanced independent CNC simulation and optimization software, VERICUT, will be hosting its ‘Composite Manufacturing Symposium’.

Mark Forth, Global Business Development Manager, asks: “Are you ready for the future of composite manufacturing? CGTech has assembled an international panel of composite manufacturing experts to discuss the challenges facing the industry today and present their experiences across multiple industries. So, attendees can glean practical knowledge and even benchmark their own progress and preparation for the predicted growth of the high-performance lightweight materials sector.”

The symposium sessions will take place in Room 513 within the Paris Nord Villepinte exhibition centre on the first day of the show, on Tuesday, 3 March, at 10:30 am to midday with a free buffet lunch until 1 pm. They will then be repeated in the afternoon from 1 pm to 2.30 pm. For more information, or to register for the symposium, contact Jodie.cosby@cgtech.com

With 44,000 visitors expected at this year’s show the organiser, JEC Group, aims to bring together the decision-makers of the end-user industries from around the world with a range of conferences and discussion groups covering the whole supply chain. This year, the organiser’s focus falls on the automotive, aerospace, and sports & health industries, covering all issues relating to composites in these strategic sectors.

“For these, and many other industry sectors, new technologies, materials and processes are transforming how components are manufactured,” Mark Forth points out. “If you are shaping the future of your company's composite manufacturing, then our Composites Symposium event will inspire and engage you with informative keynotes, a focus on innovation and will also provide networking opportunities. It really should be seen as an unmissable ‘knowledge grab’ for anyone attending JEC World.”

Visitors to JEC World can also call onto the CGTech stand, P30 in Hall 5, where live demonstrations of the latest CNC simulation software, VERICUT Version 9.0, will be offered alongside the opportunity to discuss productivity and efficiency gains.

VERICUT offers specific modules to support manufacturers in the composites sector; VERICUT Composite Programming (VCP) and VERICUT Composite Simulation (VCS).

VCP gives composite part designers complete control over their part. With a wide variety of path laying algorithms, engineers can ensure that they capture the design intent of their composite work piece. Using tools inside of VCP, the part designer or engineer can easily create and experiment with various Automated Fibre Placement (AFP) path options. They can also evaluate the effects of AFP manufacturing on a composite part’s design intent.
The user can measure and evaluate the effects of AFP path trajectory, material steering, surface curvature, course convergence and other process constraints as they would be applied in manufacturing.

VCP can be used to program any number of machines. It includes support for probing, knife trimming paths, laser projection, and Automated Tape Laying (ATL) machines. Reading CAD surfaces and ply boundary information for fibre placement from leading software systems, including CATIA, STEP, Siemens NX, Pro E, Creo, SolidWorks, or ACIS surface models.

VCS gives an entire organization the confidence needed to run composite NC machines correctly the first time. Regardless of the programming system used (VCP or others), users can verify NC code to identify issues, such as: collisions, NC syntax errors, and material placement quality. Because the material is applied to the layup form via NC program instructions in a virtual CNC simulation environment, the simulated part can be measured and inspected to ensure the NC program follows manufacturing constraints. A report showing simulation results and statistical information can be created automatically to help build confidence with operators and management. VCS can be used to simulate any number of machines, and includes support for probing, knife trimming paths, laser projection, Automated Fibre Placement (AFP), and Automated Tape Laying (ATL) machines.

For manufacturers applying robotic automation to cutting and trimming, drilling and fastening, as well as fibre placement, VERICUT simulates 6-axis articulated-arm robot motion from leading robot machine builders including Fanuc, KUKA, ABB, Kawasaki, Motorman and others. VERICUT also supports robots that have additional ‘external’ axes such as those mounted on a linear rail.

Mark Forth concludes: “Implementing automated composite manufacturing requires a significant investment, both in capital equipment and staff knowledge. This might inhibit many manufactures from applying automation, despite the clear advantages.

“To address this, we have produced a ‘Roadmap to Automated Composites’, and this paper provides a business case for adopting automated composites, pointing out considerations when deciding upon a machine. By shedding light onto these specific considerations, informed and successful steps can be taken to implement this constantly evolving technology. JEC World visitors, to our symposium or our stand, can access this information and discuss their composite challenges in confidence with CGTech staff.”

VERICUT Inspection ReportAs machining gets more complex and customers expect more for less the need for to simulate, verify and optimize the machining process has never been more compulsory in order to ensure reliability and efficiency, and to maximize productivity.
The highest level of NC simulation and verification is achieved using a highly accurate digital twin representation of the CNC machines, which are driven by the same post processed G-code or NC programs that run the machine. A digital twin means to digitally replicate real world component manufacture processes within software.

There are two critical items – are the virtual models correct, matching physical ones, and are the subroutines and parameters from the machine tool being used.

First critical aspect for simulation is making sure that the virtual models of all machine components, attachments, fixtures, clamps, cutting tools etc. match as closely as possible to what is being used on the shop floor in order to create the digital twin. The more accurate the simulation is the more reliable it will be in providing dependable outcomes.

If short cuts are taken, like omitting input data, relying on rough block size or using generic tools, it’s likely that surprises, issues and errors will arise later, which can be inconvenient and expensive on the shopfloor. This is where VERICUTs connectivity comes in.
Secondly is making sure the virtual machine uses actual parameters, subroutines and probing logic taken from the actual machine tool, making the digital twin behave exactly the same as the machine tool and its motions.

It helps having Connections

VERICUT can directly connect and communicate with multiple sources of software, including CAD/CAM, tool management systems and data from vendors and the cloud. This gives access to the most current information available and ensures that the virtual machine and simulation is as accurate as possible.

Using direct interfaces with all leading CAM systems VERICUT creates a seamless integration between the CAM system and simulation software, which streamlines data flow, avoids replication, eliminates human error and makes the transfer for multiple setups and operations quick and easy. Different stock models, design or finished parts and fixtures can be selected and imported into VERICUT ready to run a simulation – as simple and easy as that.

Likewise, with connections to various Tool management systems, including the Machining Cloud, Novo and Zoller etc. VERICUT can access a central source for cutting tool information and obtain highly accurate tool models. Other information such as speeds and feeds can be brought into VERICUT from the TDM system and used by programmers as a guideline to ensure that tools are not being over or under utilized or as a starting point for optimizing programs.

Connection goes both ways

Virtual machineConnectivity also goes beyond the information imported into VERICUT and also extends to the resulting simulation data that can be shared with other departments in order to improve efficiency. VERICUT has various tools that streamline communication and connectivity throughout the manufacturing process.

As well as reports that can be configured to run automatically after the simulation, log files, cutting data and images, VERICUT offers a complete Reviewer file. This is a file that can be opened by any Windows PC or tablet and allows users to view the full simulation. It’s a 3D representation of the simulation that can play forward and backward while removing and replacing material. The user can rotate, pan and zoom just like normal VERICUT, and the cut stock can be measured using all the standard X-Caliper tools. Tools such as reviewer and reports allow complete visibility throughout the manufacturing process of how parts should be produced and connects the entire workflow together.

Accurate simulation data means that the planning and scheduling department will have a better indication of cycle times, tool life information will be available for pre-setters, machinists will have confidence that the fixtures and programs are going to run correctly, NC Programmers can be assured that the process is actually producing the part as intended, and process engineers and quality control can easily trace errors or issues in the design or NC program. All this data can be collated before any actual machining is done, without wasting machine time, and can be fed back to high level personnel for operational planning and budgeting.

ConnectionsSo when the virtual world matches the real world chances for surprises in the shop are massively reduced, the manufacturing workflow operates more efficiently and maximizes time and therefore cost savings. VERICUT connects the process together and ensures the most accurate and reliable representation of the real world.

MACH 2020 20 to 24 April NEC Birmingham

Disruption is sometimes the only way forward says CGTech (Hall 17 Stand 330)

X caliper‘If you always do what you’ve always done, you’ll always get what you’ve always got’ is a truism that CGTech, developer of VERICUT – the world’s leading CNC simulation, verification and optimization software - has been stating to manufacturers in many industry sectors since 1988.

Visitors to the MACH 2020 exhibition (Hall 17 Stand 330) can find out from the renowned global leader in NC code simulation how the software can improve (disrupt) their business. With VERICUT, CGTech offers a wide range of products and solutions that ensure CNC machine tools run collision-free and manufacturing processes operate more efficiently with increased profit levels. Machine shops can take back control and get ahead with VERICUT.

Demonstrations of the latest features in version 9.0 of VERICUT CNC machine simulation and optimization software will be conducted on the stand, by the company’s knowledgeable technical staff. VERICUT software is the industry standard for simulating CNC machining in order to detect errors, potential collisions, or areas of inefficiency. It operates independently; but can also be integrated with leading CAM systems.

Technical Director, Gavin Powell, says: “Faster is better, with the development of our new graphics display providing significant gains for users. You can render faster with more realistic and crisper views of cutting processes and machines. With dramatic improvements in the view environment; rotate or zoom while cutting, seamlessly switch view types or layouts, and change model translucency, colours or other appearance properties at any time. New flexibility to use major functions (like Section, X-Caliper and AUTO-DIFF) in any view will help programmers get things done faster.”

‘Restart’ and ‘Stop At’ capabilities quickly verify changes made to an NC program, and have more control over the simulation. Initiate Restart action on any line in the NC Program window and the simulation quickly processes up to the restart line, then the display updates to show the result. A new Stop At Line Number/Count option enables programmers dealing with looping and branching logic to stop at a specific occurrence number of processing a line in the NC program.

CGTech will also demonstrate VERICUT’s Force optimization module at MACH. VERICUT + Force provides an integrated simulation-optimization solution that can significantly reduce machining times, improving cutting tool and machine life. New and legacy NC programs can be optimized with Force to run as efficiently and safely as possible. Force is available for milling, turning, and mill-turn machines.

Force is a physics-and mathematics-based module designed to optimize machining feed rates. The software uses actual data for cutting tool forces and spindle power readings to calculate maximum chip thickness and feed rate.

Sales Engineer, Scott Ravenscroft, explains: “VERICUT covers the obvious and visible production elements, such as crashes, scrap, gouges and prove outs; Force addresses the hidden opportunities. These include inefficient programming and suboptimal feedrates caused by the CAM system’s inability to adjust cutting feedrates for varying cutting conditions.”

Force relies on proven technology to maximize program efficiency and productivity and typically achieves savings of 8 to 15 per cent on aluminium and 15-plus per cent on difficult to cut materials. Return on investment can often be as little as one production component, with the opportunity to analyze cutting conditions, improve tool life, protect CNC machine tools and reduce operational costs.

Gavin Powell concludes: “Companies now more than ever are realizing the importance of simulation and the digital twin model. We are working closely with our customers and partners around the world to understand their exact needs, we deliver superior technical and economical solutions through the use of advanced technologies.”

VERICUT Force revolutionizes NC program optimization – interview with Gavin Powell

Gavin PowellVERICUT Force is new and is leading the way. The physics based software module for NC program optimization analyzes and optimizes cutting conditions during the entire NC program operation. Taking into consideration the respective material, cutting tools and the machining conditions, VERICUT Force generates the maximum reliable feed. Current users see it as one of the best tools in the world of machining in terms of effectiveness and usability. Gavin Powell, Technical Director at CGTech Ltd. comments on VERICUT Force in an interview.

What is Force?
Gavin Powell:
VERICUT Force is a physics-based NC program optimization software module that analyzes and optimizes cutting conditions throughout NC program operations.

Why use Force?
Gavin Powell:
It is by far the best optimization solution on the market. Force makes the most effective NC program for the given material, cutting tool, and machining conditions. The results are significant time savings, and improved cutting tool and machine life. Machining improvements are a balance between tool life and speed. Force optimization provides the flexibility to tip the scales to match your machining goals.
How can these benefits help my machine shop?
Gavin Powell:
The benefits of Force are endless - better cutting tool and machine utilization, as well as better utilization of the machinist’s time, so you can increase capacity without adding another machine and have greater confidence when running lights-out machining. There are also significant improvements in part to part and job to job consistency. All this ensures reduced cycle times, faster delivery and improved margins – ultimately making you more competitive.

How can I calculate my expected savings?
Gavin Powell:
Most users see a return on their investment in just 3-6 months. Some of our customers have paid for VERICUT Force on their first optimized project. We have a handy Force Calculator on our website so you can see for yourself exactly what Force could save you.

How does Force make my parts cut faster?
Gavin Powell:
VERICUT Force maximizes the chip thickness, keeps it constant, matches the cutting conditions to the cutting tools performance parameters all while protecting the cutting from excessive Force, feed rates, spindle power requirements.

How easy is Force to setup and use?
Gavin Powell:
Easier than any other type of NC program optimization process. User knowledge or software tests are not necessary. Force can optimize every material, on any machine tool, with any cutting tool, using any NC program – whether it’s newly created or old. We have successfully Force optimized many parts improving them further than had already been optimized by other methods.

Does Force overwrite the existing NC program
Gavin Powell:
No. it creates a separate file with a “.opti” extension. Force has a feature to display the original and opti. file side by side. With the Force graphs you can see things like cutting conditions, excessive forces, machining rates, power/torque, chip strength, material removal, tool deflections and feeds for the original and optimized program.

VERICUT Version 9 fully optimized for maximum efficiency

The latest version of VERICUT CNC simulation, verification and optimization software was released earlier this year but continues to be improved and enhanced with additional incremental releases, which maintained users are automatically.

vericut 9 optimizedVERICUT 9 is a game changer for verifying NC programs, with sharper displays, clearer views of the cutting process and better utilization of the system resources, making it easier to spot problems and imperfections in machined parts. It runs a lot of operations multi-thread and really makes use of GPUs that previous versions didn’t do.

The biggest improvement visible to the end user in VERICUT 9 is the new, more flexible and all open GL viewing environment. Users get optimal performance running simulations in a single view or multiple views, seamlessly switching between Workpiece, Machine, or Profile views, or view layouts for optimal viewing.

Users no longer have to use individual views to perform each operation – run a machine simulation, cut a section while it’s running or use X-Caliper and AUTO-DIFF all in the same window. All this runs smoother and quicker than in previous versions and streamlines the verification effort to increase productivity.

With other enhancements users can automate many processes with just a click of button. Check cutting limits, check spindle direction, check coolant, check syntax, check tools – all these can be pre-set, saved in a master template and VERICUT will run the checks automatically. These are all things that will help even the most experienced VERICUT users to use the software more effectively.

Finding and fixing problems is now quicker than ever before. Program preview quickly runs through the program without actually cutting the part, identifying machine crashes, fixture crashes and travel limit errors Issues are identified in the VERICUT logger and clicking the error it takes you directly to the block in the NC program where the error occurs where changes can be made. Using the new Restart function there is no need to verify from the start. Just verify the NC code from the line where changes have been made. This will be a huge benefit anyone verifying large NC programs.

view base machineAs well as simulation and verification enhancements, Air-Cuts only optimization allows users to optimize tool motions that are not in contact with material with. This is included in Verification, it’s easy to use and it runs while simulating. For more advanced optimization, the VERICUT Force module comes with enhanced charts for analysing cutting conditions, chip thickness and tool deflection.

“The software is constantly improving making things quicker and easier for all users” Says Gavin Powell, CGTech Ltd Technical Director. “The aim is to help our customers be more efficient, more competitive and therefore more profitable.”
