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 with
a few lines of programming.
First you pre-position the tool above the workpiece with straight-
line blocks and position with a safety clearance of 5 mm above the
hole. Then drill the hole with Cycle
G200
