Playing a Simulation Backward with Material Removal

During a NC Machine simulation with material removal you can play the simulation backwards and this adds back the material previously removed.

  1. Click Simulation Options in the Animations tab, select the Generate a recording of the Simulation for Instant Replay? check box.

    The app automatically switches to this player and each step is now recorded.

    From now, in this scenario, 16.2s, all the steps of the simulation are saved. When you run a simulation up to a time, here 33.20s, you can backward the recorded steps up to 16.2s.



    Storing this information to add removed material consumes a lot of memory, and impacts performance. So, in the simulation settings there is a maximum number, 10,000 steps to be replayed backward, minimum steps; 1, and the default value of 1000. When the max number of steps is reached, we forget the first ones in order to have the last maximum number of steps recorded. For more information, see Me > Preferences > App Preferences > Simulation > Machining > NC Machining Apps Common Services > Material Removal..

  2. Click Backward in Simulation Player.

    When this mode is active, there is always a current rough stock displayed on screen. You can always run an analysis on this rough stock (measure, comparison with the design).

    Note: Only material removed by the tools is added back. When a collision is detected (with a holder for example), the material is removed by the holder and changes to a red color. When stepping back, this removed material is not added back, as the red area is kept.
