Milling contour pocket (CYCLE63)

Function
Before you can machine a pocket with islands, you must enter the contour of the pocket and
islands. The first contour you specify is interpreted as the pocket contour and all the others
as islands.
From the programmed contours and the input screen form for stock removal, the cycle
generates a program that removes the pockets with islands from inside to outside in parallel
to the contour.
The islands can also be located partially outside the pocket or overlap each other.
