Diameter of pocket
Insertion Insertion strategy
Helical: Insertion in a helical path
The cutter center point traverses along the helical path determined by the radius and
depth per revolution. If the depth for one infeed has been reached, a full circle
motion is executed in the plane.
Feedrate: Machining feed
Center: Vertical insertion at center of pocket
The tool executes the calculated depth infeed vertically in the center of the pocket.
Feedrate: Infeed rate as programmed under FZ
Note: Vertical insertion into the pocket center can be used only if the tool can cut
across center or if the workpiece has been predrilled.
