Longitudinal groove (SLOT1)

Function
You can mill any longitudinal slot with the "longitudinal slot" milling function.
The following machining methods are available:
● Mill circular pocket from solid material.
● Predrill longitudinal slot first if, for example, the milling cutter does not cut in the center
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.

Operating Manual, 03/2013, 6FC5398-7CP40-3BA1
Depending on the dimensions of the longitudinal slot in the workpiece drawing, you can
select a corresponding reference point for the longitudinal slot.
(e.g. for ShopMill, program the drilling, rectangular pocket and position program blocks in
succession).
In this case, select the predrilling position corresponding to the "Vertical" parameter under
"Insertion".
