Programming example 3
Machining task:
Shows the program sequence of a machining task,
illustrated by two different pockets with islands. The
machining process is tool-oriented, i.e. each time a new
tool becomes available, all machining tasks requiring
this particular tool are performed complete on both
pockets before the next tool is used.
• Rough drill
• Solid machine pocket with islands
• Solid machine residual material
