Machining type: Helical
When milling circular pockets, you can select the following machining types:
● Roughing
During roughing, the circular pocket is machined downward with helical movements.
A full circle is effected down to pocket depth to remove the residual material.
The tool is retracted from the edge and base of the pocket in a quadrant and retracted with
rapid traverse to a safety clearance.
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 effected down to pocket depth to remove the residual material.
The base is milled from outside in a spiral movement.
The tool is retracted from the center of the pocket to a safety clearance.
● Edge finishing
In edge finishing, the edge is machined first with a helical movement down to the bottom.
A full circle is effected down to pocket depth to remove the residual material.
The tool is retracted from the edge and base of the pocket in a quadrant and retracted with
rapid traverse to a safety clearance.
