If the margin line was defined via the --> “Special function: machining of inlay/onlay bridges,” you can define a special machining action for this area since the geometry of an inlay differs considerably from that of a coping.

The “3D equidistant finishing” cycle is highly suitable for machining undercut-free areas.

For undercut machining, the “5X boss finishing” cycle can be used as an option depending on the geometry of the part.

Cycles

3D equidistant finishing

3D complete finishing

3D profile finishing X-direction

3D profile finishing XY-direction

5X boss finishing

Offset

In most cases it is ≥ half the tool diameter; otherwise, unmachined areas may remain.

No other function for this offset; the margin line is not protected if the value = 0.

Max. angle for red. feedrate

Value 0

Full feedrate; with a different value, the feedrate is reduced during plunge movements.

Coping-specific tilt

The “Special function: coping-specific alignment” setting was used for the part, so this area is to be machined with a specific tilt:

Yes/No

This cycle should only be used in isolated cases since the quality of the milling paths depends heavily on the geometry of the milling area.

Undercut machining

Undercut machining is to be performed: Yes/No

Desired tilt angle

approx. ≤ 4°

Max. tilt angle

approx. ≤ 8°

Here you should indicate both margin lines using the “Special function: machining of inlay/onlay bridges” option. The lines can then be parameterized with the cycles from this section.

To avoid an undercut situation, tilted machining often requires the “Special function: coping-specific alignment” setting.
