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.
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.

Dwell time at feed interruption
With zero: Without dwell time
Lift-off distance from the contour - (only for ∇ and ∇ + ∇∇∇)
With zero: Automatic lift-off distance from the contour - (only for ∇ and ∇ + ∇∇∇)
machining, it is at the left or right.
The starting point is marked in the help display.
Always round on the contour
Only round to the previous intersection
