Circular pocket (POCKET4)

Function
You can use the "Circular pocket" cycle to mill circular pockets on the face or peripheral
surface.
The following machining variants are available:
● Mill circular pocket from solid material.
● Predrill circular pocket in the center first if, for example, the milling cutter does not cut in the
center (program the drilling, circular pocket and position program blocks in succession).
For milling with the "Circular pocket" function two methods are available: the plane-by-plane
method and the helical method.
Clamping the spindle
For ShopTurn, the "Clamp spindle" function can be set up by the machine manufacturer.
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 during plane-by-plane machining
In plane-by-plane machining of the circular pocket, the material is removed horizontally, one
layer at a time.
1. The tool approaches the center point of the pocket at rapid traverse at the height of the
retraction plane and adjusts to the safety distance.
2. The tool is inserted into the material according to the method selected.
3. The circular pocket is always machined from inside out using the selected machining
method.
4. The tool moves back to the safety distance at rapid traverse.
