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 for plane-by-plane solid 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 clearance.
2. The tool is inserted into the material according to the chosen strategy.
3. The circular pocket is always machined from inside out using the selected machining
method.
4. The tool moves back to the safety clearance at rapid traverse.
Approach/retraction for helical solid machining
In helical reaming, 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 clearance.
2. Infeed to the first machining diameter.
3. The circular pocket is machined with the chosen machining type up to pocket depth or up
to pocket depth with finishing allowance.
4. The tool moves back to the safety clearance at rapid traverse.
5. Lateral infeed to the next machining diameter.
Machining type: Plane-by-plane
When milling circular pockets, you can select the following machining types:
● Roughing
During roughing, the individual planes of the circular pocket are machined one after the
other from center point until depth Z1 is reached.
● Finishing
During finishing, the edge is always machined first. The pocket edge is approached on the
quadrant that joins the pocket radius. In the last infeed, the base is finished from the center
out.
