Milling a rectangular pocket
In the DISTANCE-TO-GO operating mode you can use the POSITIP
for milling a rectangular pocket.
The information for rectangular pocket milling can also be written
to a machining program as a "cycle" (see Chapter I-4).
You select the cycle with the soft key "Pocket Milling" (second
soft-key row), and enter the required data. This data can usually be
taken quite easily from the workpiece drawing (e.g. the side
lengths and the depth of the pockets).
The POSITIP calculates the rough-out paths and offers graphic
positioning aid.
