Implicit Tool Motions
In order to automate the process of customizing a tool path as much as possible, the following Tool Motions are implicitly created in Milling:
A Retract motion is implicitly created before an Automatic Cut motion if other tool motions are already present.
An implicit Plunge motion (Auto Plunge) is created where the tool automatically plunges to the beginning of an Automatic Cut.
If you are not satisfied with the implicitly created motions, you can delete or redefine them.
