Hello Odd Egeland,
madCAM saves the search path to the saved cutter with each toolpath. By default, the feed and speed is used from the saved cutters. You can also change the feed and speed temporarily when post processing.
There are several ways to change the depth of a toolpath and you can even move the toolpath directly in Rhino before post processing. It is also possible to control the height and depth of a 3D toopath by using the clipping planes.
