Milling a Rectangle Pocket
In the operating mode DISTANCE-TO-GO you can use the POSITIP 880
for milling a rectangle pocket.
The information for rectangle pocket milling can also be written to a
machining program as a cycle.
Select the cycle with the RECTANGLE POCKET soft key, and enter the
required data. This data can usually be taken quite easily from the
workpiece drawing (e.g. the axis size and the depth of the pockets).
The POSITIP 880 calculates the rough-out paths and offers graphic
positioning aid.
Finish allowance
The amount of material to be left for machining on the last pass around
the pocket.
