Face milling (CYCLE61)

Function
You can face mill any workpiece with the "Face milling" cycle.
A rectangular surface is always machined. The rectangle results from corner points 1 and 2
that are pre-assigned with the values of the blank part dimensions from the program header.
Workpieces with and without limits can be face-milled.
Note
If face milling is opened using a softkey, then the corner points X and Y from the program
header are transferred. Further, Z0 and the abs/inc selection from X1, Y1 are also
transferred.
Approach/retraction
1. For vertical machining, the starting point is always at the top or bottom. For horizontal
2. Machining is performed from outside to inside, if possible.
Machining type
The cycle makes a distinction between roughing and finishing:
● Roughing:
● Finishing:
Depth infeed always takes place outside the workpiece.
For a workpiece with edge breaking, select the rectangular spigot cycle.
In face milling, the effective tool diameter for a tool of type "Milling cutter" is stored in a
machine data item.
