Descrizione

The Adaptive tool uses an adaptive algorithm to create clearing and profiling paths that manage cutter engagement so that engagement and material removal never exceed a maximum value.

Utilizzo

Usage instructions for the Adaptive operation are presented here.

Basic Operation

  1. Press the Adaptive icon, or select the CAM Adaptive from the top menu.
  2. Select the tool controller for the Operation from the Tool controller dialogue pop up window, if prompted.
  3. Adjust the operation depths as needed in the Depths tab: Start Depth, Finish Depth, Step Down.
  4. Make adjustments in Heights tab if needed.
  5. Configure settings in the Operations tab:
    1. (See the Properties → Adaptive section below.)
    2. Set the Step Over value as a percentage of the diameter of the Tool.
  6. If you wish to preview the result before accepting the settings, click Apply
  7. Click OK button to confirm and generate paths.
Preliminary Notes About Adaptive Clearing
  • Depending on the size and complexity of the area for the operation, is might be better to not recompute the operation after every property change; rather, consider:
    • deactivate the operation with the Active toggle tool, make your changes to the operation's properties, then click the Active icon again to re-activate the operation - which triggers a recompute internally.
  • The Adaptive operation might contain a few bugs yet to be clearly identified. Please report bugs and issues in the FreeCAD Path/CAM Forum.
  • All tool shapes may not be respected with this operation. Check the FreeCAD forum for further details.
  • Should you choose to run the path simulator in the CAM Workbench, it only uses the standard end mill to simulate paths. Therefore, you will not see tool-shape-specific material removal. Material removal is shown using the end mill shape.
