Input simple
For simple machining operations, you have the option to reduce the wide variety of
parameters to the most important parameters using the "Input" selection field. In this "Input
simple" mode, the hidden parameters are allocated a fixed value that cannot be adjusted.
If the workpiece programming requires it, you can display and change all of the parameters
using "Input complete".
Approach/retraction during plane-by-plane machining
In plane-by-plane machining of the circular pocket, the material is removed horizontally, one
layer at a time.
1. The tool approaches the center point of the pocket at rapid traverse at the height of the
retraction plane and adjusts to the safety distance.
2. The tool is inserted into the material according to the method selected.
3. The circular pocket is always machined from inside out using the selected machining
method.
4. The tool moves back to the safety distance at rapid traverse.
Approach/retraction during helical machining
In helical machining, the material is removed down to pocket depth in a helical movement.
1. The tool approaches the center point of the pocket at rapid traverse at the height of the
retraction plane and adjusts to the safety distance.
2. Infeed to the first machining diameter.
3. The circular pocket is machined to pocket depth using the selected machining method.
4. The tool moves back to the safety distance at rapid traverse.
