    The Path Deburr.svg Deburr tool is primarily for Deburring an edge.


    1. There are several ways to invoke the command:
      • Press the Path Deburr.svg Deburr button.
      • Select the Path → Path Deburr.svg Deburr option from the menu.
    2. The Deburr task panel opens. See Options.
    3. Select Base Geometry.
    4. Specify the required parameters.
    5. Press the OK button.


    After selecting the geometry in the Base Geometry section of the task panel you can press Apply to see the tool path as defined by the default options.

    Next you can check your depths/step down and heights, just like with other path commands.

    The Final step is to activate the Operation section where you can specify the following:

    • Tool controller: Select the tool to use.
    • Coolant Mode: Select None, Flood or Mist.
    • Directions: Select CW (clockwise) or CCW (counter-clockwise).
    • W: The dimension of your edge.
    • h: The offset from the bottom of the tool. It's a safety feature because if the tip gets above the edge it won't cut anymore.
