First you pre-position the tool in L blocks (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 1 PECKING.
Straight-line function G00 (see “Straight line at rapid traverse G00
Straight line with feed rate G01 F. .” on page 231), Cycle G200
DRILLING (see “ROTATION (Cycle G200)” on page 312).
