Longitudinal groove (SLOT1)

Function
You can mill any longitudinal groove with the "longitudinal groove" milling function.
The following machining methods are available:
● Mill longitudinal groove from solid material.
● Pre-drill longitudinal groove in the center first if, for example, the milling cutter does not
Depending on the dimensions of the longitudinal groove in the workpiece drawing, you can
select a corresponding reference point for the longitudinal groove.
Approach/retraction
1. The tool moves at rapid traverse to the retraction plane and infeeds at safety clearance.
2. The tool is inserted into the material according to the chosen strategy.
3. The longitudinal slot is always machined with the chosen machining type from inside out.
4. The tool moves back to the safety clearance at rapid traverse.

succession).
