Machining type: Plane by plane
When milling circular pockets, you can select these methods for the following machining
types:
● Roughing
Roughing involves machining the individual planes of the circular pocket one after the
other from the center out, until depth Z1 or X1 is reached.
● Finishing
During finishing, the edge is always machined first. The pocket edge is approached on
the quadrant that joins the pocket radius. During the last infeed, the base is finished from
the center out.
● Edge finishing
Edge finishing is performed in the same way as finishing, except that the last infeed
(finish base) is omitted.
When milling circular pockets, you can select these methods for the following machining
types:
● Roughing
During roughing, the circular pocket is machined downward with helical movements.
A full circle is made at pocket depth to remove the residual material.
The tool is removed from the edge and base in the quadrant and retracted with rapid
traverse to the safety distance.
This process is repeated layer by layer, from inside out, until the circular pocket has been
completely machined.
● Finishing
In finishing mode, the edge is machined first with a helical movement down to the bottom.
A full circle is made at pocket depth to remove the residual material.
The base is milled from outside in, using a spiral movement.
The tool is retracted with rapid traverse from the center of the pocket to a safety distance.
● Edge finishing
In edge finishing, the edge is machined first with a helical movement down to the bottom.
A full circle is made at pocket depth to remove the residual material.
The tool is removed from the edge and base in the quadrant and retracted with rapid
traverse to the safety distance.
