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.
Various defined values can be pre
-assigned using setting data.
Please refer to the machine manufacturer's specifications.
If the workpiece programming requires it, you can display and change all of the parameters
using "Input complete".
1. At the height of the retraction plane, the tool approaches the center point of the semicircle
at the end of the groove at rapid traverse and adjusts to the safety distance.
2. It is then inserted into the workpiece at the machining feedrate, allowing for the maximum
Z direction infeed (for face machining), X direction infeed (for peripheral machining), and
the finishing allowance. Depending on the machining direction (up-cut or down-cut), the
circumferential groove is machined in a clockwise or counterclockwise direction.
3. When the first circumferential groove is finished, the tool moves to the retraction plane at
rapid traverse.
4. The next circumferential groove is approached along a straight line or circular path and
then machined.
5. The rapid traverse feedrate for positioning on a circular path is specified in a machine
data element.
You can select the machining mode for milling the circumferential groove as follows:
● Roughing
During roughing, the individual planes of the groove are machined one after the other
from the center point of the semicircle at the end of the groove until depth Z1 is reached.
● Finishing
In "Finishing" mode, the edge is always machined first until depth Z1 is reached. The
groove edge is approached on the quadrant that joins the radius. In the last infeed, the
base is finished from the center point of the semicircle to the end of the groove.
● Edge finishing
Edge finishing is performed in the same way as finishing, except that the last infeed
(finish base) is omitted.
● Chamfering
Chamfering involves edge breaking at the upper edge of the circumferential groove.
