Fitting

You define here how the lead in and lead out arcs of the retract movements fit to the machining pass.

Machine the whole pass

With this option the complete pass is machined. The arc can be applied at the end of the pass, without trimming of the pass.

The arc can be inserted only if it can be done safely without gouging the part faces. When the arc is conflicting with the model geometry, a straight vertical lead in/out movement is performed.

Minimize trimming

This option enables you to perform the arc retract movement with minimal possible trimming of the cutting tool pass. The retract pass is as close to the surface as possible, maintaining a minimum distance from the surface to fit the arc of the defined radius.

Fully trim pass

In cases where it is crucial to prevent over-machining, this is a good and cautious strategy modification. The pass is trimmed back so the entire arc fits into it, but no nearer than a full machine pass link would be.
