A notable feature in HSM Performance Pack is the ability to force machining at a specified z-level. In some cases, this option allows you to achieve ideal machining results by avoiding having to create unnecessary operations while still retaining optimal linking and ordering.
In the image below, toolpath on left is without forced machining and the toolpath on the right is with forced machining.
To specify fixed z-levels, you must select one or more points and set their Type to “Z-level”. The Z-coordinates of these points are then used as fixed z-levels in HSM Performance Pack. This option is available for Pocket3D, Contour3D and ConstantCut3D.
