Circular pocket - POCKET4

Function
You can use the "Circular pocket" cycle to mill any circular pockets on the face or peripheral
surface. .
The following machining variants are available:
● Mill circular pocket from solid material.
● Pre-drill circular pocket in the center first if, for example, the milling cutter does not cut in
For milling with the "Circular pocket" function two methods are available: the plane-by-plane
method and the helical method.
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
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
4. The tool moves back to the safety distance at rapid traverse.

Description
Complete machining
•
The rectangular pocket is milled from the solid material.
Editing
•
The size of any existing smaller rectangular pocket or hole is increased in
several axes. You must program parameters AZ, W1 and L1 for this purpose.
