Chamfer
Single pos.
Pos. pattern
A
circular spigot is machined at the programmed position (X0, Y0, Z0).
Several circular spigots are machined in a position pattern (e.g. full circle, matrix,
line).

The positions refer to the reference point:
Position in X direction (single position only), abs. or inc.
Position in Y direction (single position only), abs. or inc.
Workpiece height (single position only), abs. or inc.

3.8.6 Longitudinal slot
Use the "Longitudinal slot" function if you want to mill any kind of
longitudinal slot.
The following machining methods are available:
• Mill longitudinal slot from solid material.
• Predrill longitudinal slot in the center first if, for example, the
milling cutter does not cut across center (program the drilling,
rectangular pocket and position program blocks one after
another).
Depending on the dimensions of the longitudinal slot in the workpiece
drawing, you can select a corresponding reference point for the
longitudinal slot.
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.
