Generating the rest roughing toolpath

On the Model Rest Area Clearance dialog:

  1. Select the Rest page, and:
    1. From Rest Machining type list, select Toolpath.
    2. From the Toolpath list, select Roughing (the name of your roughing toolpath).
    3. In the Detect Material Thicker Than field, enter 0.2 mm. The calculation ignores rest material thinner than 0.2 mm. This helps to avoid thin regions being rest roughed where the benefit of a second cut is negligible.
    4. In the Expand Area By field, enter: 0.2 mm. The rest areas are expanded by 0.2 mm (measured along the surface). This can be used in conjunction with Detect Material Thicker Than to reduce the areas to be machined to the essentials (such as, corners), and then to offset these areas slightly to ensure that all details (for example, on the corners) are machined.
  2. Click Calculate to generate the toolpath.

    Progress is shown on the Status bar at the bottom of the screen. The generation may take a minute or so, depending on the processing power of your PC.

  3. After the toolpath is generated, Close the strategy dialog.
