CNC G-Code Simulator

ICAM’s Virtual Machine®

Detect & Eliminate Collisions, Surface Gouges & More with a High-Precision CNC Simulator

Compared to traditional APT-based simulation systems, which only simulate the planned tool-path, ICAM’s Virtual Machine® delivers for a more meaningful simulation, accurately recreating how the machine tool will react to the G-code generated by your post-processor.

The simulator provides a powerful validation method allowing users to determine the association between G-code and specific operations inside the NC program and allows for specific modifications to the CAD/CAM NC program depending on the simulation results.

Supports a Wide Range of CAD/CAM Systems

Virtual Machine® is built for complete compatibility with all major CAD/CAM systems like CATIA, NX CAM, creo & Mastercam. This flexibility allows the software to be quickly and easily integrated into your existing workflow with minimal implementation time.

Cutting-Edge Features to Meet the Biggest Machining Challenges

ICAM’s Virtual Machine® has helped countless manufacturers gain a competitive edge by reducing costly CNC machine collisions and repetitive shop-floor proofing of parts through its advanced set of features.


Supports Mill/Turn Machining Centers

Virtual Machine® features full support for mill/turn centers including synchronizing dual turret merging lathes, accurately simulating constant surface speed as well as defining and modeling lathe tool inserts and generic 3D tool holders. Virtual Machine® also provides the environment to define a rotary axis as either a spindle or a lathe tool turret providing greater support for different machines.



This feature supports Virtual Machine® simulation of manufacturing processes that involve one or more changes of clamping and/or part location on the machine. Multi-setup also automatically tracks the in-process stock state as a part progresses from one manufacturing program to another.

Simulation Recording

This feature automatically records the complete post-processing and simulation session for later review and analysis. Programs can be post-processed with Virtual Machine® simulation overnight and/or in the background and then later viewed on the same or a different workstation.

Material Removal

Virtual Machine® supports superior material removal capabilities for in-process stock collision and gouge detection. This functionality allows NC programmers to compare the processed stock model to the original CAD/CAM design. Virtual Machine® computes in-process stock geometry to identify and display gouges, excess material, inaccessible areas and rapid-motion collisions during the post-processing and verification phase.

Unique Timeline Control

Virtual Machine® offers a unique Timeline Control that provides bi-directional review and playback of NC programs at any moment within the machining cycle. This unique function allows programmers to visualize and test NC post-processor for maximum output optimization.

Cost-Effective NC Tape Proofing

Virtual Machine® detects and corrects collisions between machine components, in real-time, during post-processing. As a result, Virtual Machine® reduces scrap materials and minimizes tool replacements, while increasing machine utilization and improving part quality.

More Efficient Post & Model Development

The machine tool and controller data for both Virtual Machine and CAM-POST® are stored and managed in the same database. This eliminates the error-prone and time-consuming alternative of entering the same data twice when using a non-integrated solution.

Machine Tool Motion Simulation

Virtual Machine® may be synchronized with the CAM-POST® interface at any collision or over-travel error; thereby, allowing the user to graphically examine the part program and tape output precisely where the problem occurred. With this powerful tool, errors that could have damaged the part, tool and fixture can be eliminated.

A CNC Simulator with Real-World Savings

Virtual Machine® is designed from the gate to deliver substantial savings in NC programming time. By testing while you develop your post-processor, you can considerably cut down on the time you spend testing, modifying and retesting your CAM code.

” Before we purchased ICAM, programmers at C.E. Machine had to generate  NCI through the CAM software, use a third party post-processing software to post, and then import all part, stock, and tool models into a separate verification software before programs could be sent to the shop floor.  With the solution ICAM has provided, programmers now use a single software suite to do all of the above simultaneously. “
