Face milling (CYCLE61)

Function
You can face mill any workpiece with the "Face milling" cycle.
A rectangular surface is always machined.
Workpieces with and without limits can be face-milled.
Approach/retraction
1. For vertical machining, the starting point is always at the top or bottom. For horizontal
machining, it is at the left or right.
The starting point is marked in the help display.
2. Machining is performed from the outside to the inside.
Machining type
The cycle makes a distinction between roughing and finishing:
● Roughing:
Milling the surface
Tool turns above the workpiece edge
● Finishing:
Milling the surface once
Tool turns at safety distance in the X/Y plane
Retraction of milling cutter
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.
Selecting the machining direction
