Using VM with GENER and CERUN

This section describes how to select Virtual Machine models for use both with Icam Post GENER and with Control Emulator CERUN. It explains the post-processor command interface that can be used with GENER to control the simulation. It also describes a common user interface (UI) made available by both GENER and CERUN that you can use to view and manipulate the model during the simulation, as well as to define cutting tools, holding fixtures, finish part, rough stock, and workpiece and tool compensations used to validate the simulation.

VM provides the ability to test for axis overtravel and for collisions between various components of the machine and those of the part being manufactured. GENER and CERUN use this information to report problems, and GENER can use this information in some instances to correct problems before they occur.

The following is a list of things you should know to effectively use VM. Each of these topics is discussed in the sections that follow.

• Selecting a Virtual Machine Model
• Controlling Virtual Machine from the Part Program (GENER only)
• Activating the Simulation Windows
• Adjusting Lighting
• Adding Parts, Fixtures and Stock to the Simulation
• Setting Fixture Compensation
• Adding Tooling Definitions to the Simulation
• Setting Tool Compensation
• Monitoring Virtual Machine’s Results
• Part / Stock Comparison
• Measurement

The steps outlined in this section are not all necessary, but the completeness and accuracy of the simulation depends on complete and accurate data. At a minimum, tool compensation and fixture compensation are needed to validate travel and machine related collisions. At a minimum, tool definitions are needed to validate tool related collisions. Part and fixture definitions improve the collision detection process. Stock definitions are required to take advantage of material removal simulation for part verification purposes.
