Use the Tool axis smoothing page to smooth any changes in the tool axis angle and so minimize judder on the machine tool.
Tool axis smoothing — Select this option to enable the settings on the Tool Axis Smoothing page.
Coordinate system — Displays the coordinate system that PartMaker uses for tool axis smoothing.
Elevation
Maximum angular correction — Enter the maximum angular correction for the elevation angle. The maximum angular correction angle is only exceeded if the unsmoothed toolpath moves by more than this value in less than the Smoothing distance. In such regions, the angle may change by more than the Maximum angular correction to give a smooth results.
Azimuth
Maximum angular correction — Enter the maximum angular correction for the azimuth angle. The maximum angular correction angle is only exceeded if the unsmoothed toolpath moves by more than this value in less than the Smoothing distance. In such regions, the angle may change by more than the Maximum angular correction to give a smooth results.
Smoothing distance — Enter the distance over which to smooth the tool axis movement. With sudden changes in direction in a toolpath (such as a right-angled corner), rapid changes of orientation of the tool axis leaves dwell marks. To prevent this, the Smoothing distance blends the change in orientation to produce a much improved surface finish.
