Programming technology functions (cycles)
10.5 Contour milling
Machining
You program the machining of contour pockets with islands/blank contour with spigots, e.g.
as follows:
1. Enter the pocket contour/blank contour
2. Enter the island/spigot contour
3. Call the contour for pocket contour/blank contour or island/spigot contour (only for G code
program)
4. Center (this is only possible for pocket contour)
5. Predrill (this is only possible for pocket contour)
6. Solid machine/machine pocket / spigot - roughing
7. Solid machine/machine remaining material - roughing
8. Finishing (base/edge)
9. Chamfering
Note
The following error messages can occur when chamfering inside contours:
Safety clearance in the program header too large
This error message appears when chamfering would, in principle, be possible with the
parameters entered for FS and ZFS, but the safety clearance then could not be maintained.
Immersion depth too large
This error message appears when chamfering would be possible through the reduction of
the immersion depth ZFS.
Tool diameter too large
This error message appears when the tool would already damage the edges during
insertion. In this case, the chamfer FS must be reduced.
Name convention
For multi-channel systems, cycles attach a "_C" and a two-digit number of the specific channel
to the names of the programs to be generated, e.g. for channel 1 "_C01". This is the reason
that the name of the main program must not end with "_C" and a two-digit number. This is
monitored by the cycles.

Software option
For solid machining residual material, you require the option "residual material
detection and machining".
