If the machining operation requires several points of insertion, the retraction height can
be programmed:
to RP
•
Z0 + safety clearance
•
When making the transition to the next insertion point, the tool returns to this height. If
there are no elements larger than Z0 in the pocket area, "Z0 + safety clearance" can be
selected as the lift mode.

Milling contour spigot (CYCLE63)
Function
You can mill any spigot using the "Mill spigot" cycle.
Before you mill the spigot, you must first enter a blank contour and then one or more spigot
contours. The blank contour defines the area, outside of which there is no material, i.e. the
tool moves with rapid traverse there. Material is then removed between the blank contour
and spigot contour.
Machining type
You can select the machining mode (roughing, base finishing, edge finishing, chamfer) for
milling. If you want to rough and then finish, you have to call the machining cycle twice
(Block 1 = roughing, Block 2 = finishing). The programmed parameters are retained when
the cycle is called for the second time.
Approach/retraction
1. The tool approaches the starting point in rapid traverse at the height of the retraction
2. The tool first infeeds to the machining depth and then approaches the spigot contour from
3. The spigot is machined in parallel with the contours from the outside in. The direction is
4. When the first plane of the spigot has been machined, the tool retracts from the contour
5. The spigot is again approached in a quadrant and machine in parallel with the contours
6. Steps 4 and 5 are repeated until the programmed spigot depth is reached.
7. The tool moves back to the safety clearance in rapid traverse.
