10.4 Milling
Input simple
For simple machining operations, you have the option to reduce the wide variety of parameters
to the most important parameters using the "Input" selection field. In this "Input simple" mode,
the hidden parameters are allocated a fixed value that cannot be adjusted.
If the workpiece programming requires it, you can display and change all of the parameters
using "Input complete".
Approach/retraction
1. The tool approaches the starting point at rapid traverse at the height of the retraction plane
and is fed in to the safety clearance. The starting point is always on the positive X axis.
2. The tool approaches the spigot contour sideways in a semicircle at machining feedrate. The
tool first executes infeed at machining depth and then moves in the plane. The circular
spigot is machined depending on the programmed machining direction (up-cut/down-cut) in
a clockwise or counterclockwise direction.
3. When the circular spigot has been traversed once, the tool retracts from the contour in a
semicircle and then infeed to the next machining depth is performed.
4. The circular spigot is approached again in a semicircle and traversed once. This process is
repeated until the programmed spigot depth is reached.
5. The tool moves back to the safety clearance at rapid traverse.
Machining type
You can select the machining mode for milling the circular spigot as follows:
● Roughing
Roughing involves moving round the circular spigot until the programmed finishing
allowance has been reached.
● Finishing
If you have programmed a finishing allowance, the circular spigot is moved around until
depth Z1 is reached.
● Chamfering
Chamfering involves edge breaking at the upper edge of the circular spigot.
Note
During chamfering, the end mill behaves like a centering tool with a 90° tip angle.
