3.2 Units—Predrilling in Y axis
"Predrill, pocket mill, ICP in YZ plane" unit
The unit determines the hole position and machines the hole. The
subsequent milling cycle obtains the hole position from the reference
stored in NF. If the pocket consists of multiple sections, the unit
machines a hole for each section.
