Using Collision in the Machining Simulation

You can start the Live Machine simulation and perform collision analyses during a simulation.

When you start a simulation in the Live NC simulation environment, the following clashes are detected during simulation without any interference probes defined:

  • Machine Head, Turret, or the part/product, which mounts the tool.
  • All used tools and tool assemblies versus the machine bed/spindle, which is the part where the work-piece is attached.
  • Design part and fixtures as defined in the Part Operation.

In addition, if material removal is enabled, the clash is also detected between tools, tool assemblies, and the rough stock. It is also detected when the cutting part of the tool assembly is in RAPID move or is greater than the Maximum Feed Rate. Any other part of the tool assembly colliding with the rough stock is always detected as a clash.

Note: The design, rough stock, and fixtures must be defined as separate 3DParts, since objects are checked for collision at this level. You can display the Fault List at any time during simulation.

  1. From the Analysis & Output section of the action bar, click New Interference .
    The Interference Specifications dialog box appears.
  2. In the Context tab, select Groups against groups.
  3. Create interference probes to enable clash detection.
  4. Click OK.
    This is added to the current scenario.
  5. Right-click Interference.1 for the context menu.
  6. Select Add to Current Scenario (Interrupt).
  7. Right-click the Facing, and Select Starts Machine Simulation from the context menu.

    The simulation happens as per the tool path of the machining operations. The machine simulation traces the generated tool path.

    Note: If the Mill-Turn machine is the ASO, then the simulation is launched on the part operation. If a milling machine or a Turret is the ASO, then the simulation starts on the corresponding manufacturing program.
  8. From the Analysis & Output section of the action bar, click Display Fault List .
    The Fault List dialog box appears and lists in detail the faults encountered during simulation. Collisions (including material removal collisions) encountered during simulation appear in red, and tools, tool shanks, or stock are outlined in the work area.
  9. To choose the simulation results to list in the dialog box, click Part Operation/ Program, Recent Activity, or Scenario Results in the Choose Result section.
    The results of the simulation type that you chose are listed in the dialog box.

When a line is clicked in the Fault List, the machine is positioned at the location of the collision. The rough stock is displayed (yellow) as it was when the collision occurred and the volume in collision is displayed (red) if the option is active. Continuous collisions are displayed as one line in the fault list.

The Simulation Log also gives a brief description.
