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
1. The tool approaches the starting point at rapid traverse at the height of the retraction plane
and is fed in to the safety clearance.
2. The tool traverses the multi-edge in a quadrant at machining feedrate. The tool first
executes infeed at machining depth and then moves in the plane. The multi-edge is
machined depending on the programmed machining direction (up-cut/down-cut) in a
clockwise or counterclockwise direction.
3. When the first plane has been machined, the tool retracts from the contour in a quadrant
and then infeed to the next machining depth is performed.
4. The multi-edge is traversed again in a quadrant. This process is repeated until the depth
of the multi-edge has been reached.
5. The tool retracts to the safety clearance at rapid traverse.
Note
A multi-edge with more than two edges is traversed helically; with a single or double edge,
each edge is machined separately.
