ICAM Virtual Machine for Graphic Machine Tool Simulation V18

Virtual Machine- Graphic NC Post-Processing- seamlessly unites ICAM’s advanced NC post-processing solution, CAM-POST®, with a comprehensive graphical machine tool simulator, in one single integrated platform.

Virtual Machine enables NC programmers to graphically simulate and test programs, easily and automatically, against collisions during post-processing.

Virtual Machine allows NC programmers to avoid and correct possible programming errors that may have resulted in costly machine tool collisions and defective parts.

Graphic NC Post-Processing

Graphic NC post-processing is a real-time graphic simulation of the block-to-block machine tool motion instructions generated by the NC post-processor.

Graphic NC post-processing technology uses a single, complete database to simultaneously execute the NC post-processor engine and graphics engine.

Since the two technologies are fully integrated and the graphics engine provides real-time feedback to the post-processor, manufacturing issues such as machine collisions and over-travel are automatically detected and repaired.
Mill / Turn Center Support

Virtual Machine features all the necessary software components to fully support Mill / Turn centers including the ability to synchronize dual turret merging lathes, the capacity to accurately simulate constant surface speed as well as the provision to define and model 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.

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.

Material Removal / Verification

Virtual Machine V18 now supports Material Removal / Verification capabilities for in-process stock collision and gouge detection within a completely simulated machining environment. Material Removal / Verification is available for 3-axis and 5-axis machining applications, allows NC programmers to compare the processed stock model to the original CAD / CAM design. Virtual Machine computes in-process stock geometry to identify, list and display surface gouges, excess material, inaccessible areas and rapid-motion collisions at any time during the post-processing and verification phase.

Virtual Machine Feature / Benefit Highlights

Efficient Post-Processor and Machine 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.

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.

Leverage Existing Technology
Virtual Machine works with existing NC post-processors generated by NC manufacturing experts utilizing CAM-POST. Subsequently, existing post-processors can be tested for errors and updated automatically within a single user interface.

Shortened Learning Curve for CAM-POST Users
Virtual Machine is integrated within the CAM-POST user interface; thereby, eliminating the need to learn two different products or applications. In addition, there is no need to learn a new CAD system, simply import the machine model geometry from any current CAD solution.

Machine Tool Motion Inspection
Virtual Machine may be synchronized with CAM-POST’s interface at any collision or over-travel error; thereby, allowing the NC programmer 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.

Virtual Machine Provides a Training Environment for NC Programmers
Virtual Machine’s unique software environment provides NC programmers with a comprehensive understanding of their machine tool. With its intuitive user interface, Virtual Machine may be used as an efficient, cost-effective training tool that allows NC programmers and machine operators to explore advanced features of their machine tools and test their NC programs, off-line, in a virtual environment.
