Simulating Material Removal in Video Mode

You can simulate the material removed by Machining Operations in video mode.

Customizing options are available. See Photo/Video and Simulation.

Before you begin:
  • Go to Tools > Options > Machining > Photo/Video and Simulation to customize the settings for the simulation. See Photo/Video and Simulation.
  • A de-activated Machining Operation or Manufacturing Program cannot be replayed. You must re-activate them using their contextual menu.
  • See also Replaying the Tool Path for display settings.

  1. In this example, the part is displayed held in place by fixtures. The stock is in hide mode.



    Right-click the Machining Operation in the Manufacturing Program (in our example Facing.1), then select Tool Path Replay . SeeAbout NC Manufacturing Verification.

    The Tool Path Replay dialog box appears.

    There are four video simulation modes:


    • Full Video: performs a video simulation for the complete Manufacturing Program or Part Operation (depending on the setting, see Photo/Video.)
    • Video from Last Saved Result: performs a video simulation from the saved result of the previous video simulation.
    • Mixed Photo/Video: performs a photo simulation up to the Machining Operation just before the selected Machining Operation, then performs a video simulation on the selected Machining Operation.
    • Video from Last Intermediate Stock: performs a video simulation starting from the input intermediate stock of the Machining Operation.

  2. Select Full Video .

    The PPR Editor window switches to a window entitled Video.

  3. Select Video Options

    The Video Options dialog box is displayed.

  4. Select:

    • the Stop at tool change check box to make the simulation stop each time a tool change is encountered in the program.
    • the desired Collisions detection option to either:
      • ignore collisions during the video simulation
      • stop the Video simulation at the first collision
      • continue the Video simulation even when collisions are detected. In this case, you can consult the list of collisions at the end of the simulation.
    • the Touch is Collision check box to detect collisions of touch (or contact) type.
    • the Video simulation in protected mode check box to continue the video simulation by skipping any cut that causes errors.

  5. Click to run the material removal simulation of the Machining Operation.



    Notes: If the replay mode is set to:

    • , i.e. point to point, the number of points value specifies the number of points to be run through at each step of the replay.
    • , i.e. continuous, the slider position is taken into account for adjusting the speed of the simulation. For improved performance, intermediate graphics are not updated when the slider is used to increase simulation speed.
    • See Replaying the Tool Path for more information on replay modes.

  6. Control the material simulation video using the following control buttons and keyboard shortcuts:

    • or F5: positions the tool at the start of the simulation.
    • or F6: runs the simulation backward.
    • or F4: pauses the simulation
    • or F7: runs the simulation forward.
    • or F8: runs forward up to the end of simulation.

      Note:

      • No intermediate graphics update is made to save on rendering time.
      • A progress indicator shows the computation progression and the final machined stock appears.

  7. Right-click another Machining Operation (in our example, Pocketing.2), then select Tool Path Replay .

    1. Select Full Video to run the video from the start of the Manufacturing Program up to the selected Machining Operation.

    The figure below shows the state of the material removal simulation at the end of the Pocketing.2 operation.

  8. Repeat the steps described above to run the video from the start of the Manufacturing Program up to the last Machining Operation (in our example, Pocketing.6).

    The figure below shows the state of the material removal simulation at the end of the Pocketing.6 operation.

  9. Click OK to close the dialog box.
