Example 1
A hole with a depth of 20 mm is to be drilled into a single workpiece.
After clamping and aligning the workpiece and setting the datum, you
can program and execute the drilling operation in a few lines.
First you pre-position the tool with straight-line blocks to the hole
center coordinates at a setup clearance of 5 mm above the workpiece
surface. Then drill the hole with Cycle 200 DRILLING.
Straight-line function: See "Straight line L", page 236, DRILLING cycle:
See User’s Manual, Cycles, Cycle 200 DRILLING.
