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 G200 Drilling.
Straight-line function G00 (see “Straight line at rapid traverse G00
Straight line with feed rate G01 F. . .” on page 165), Cycle G200 Drilling
(see “DRILLING (Cycle G200)” on page 225).
