3. Select suitable coordinate offset (frame).
4. Positioning.
5. Program OFFN.
6. Select TRC.
7. Approach block (position TRC and approach groove side).
8. Groove center line contour.
9. Deselect TRC.
10.Retraction block (retract TRC and move away from groove side).
11.Positioning.
12.TRAFOOF.
13.Reselect original coordinate shift (frame).
Contour offset (OFFN)
In order to mill grooves using TRACYL transformation 513, the center line of the groove and half
of the groove width via the OFFN address are programmed in the part program.
To avoid damage to the groove side, OFFN acts only when the tool radius compensation is
active.
It is possible to change OFFN within a part program. This allows the groove center line to be
offset from the center:
