Example: Using drilling cycles in connection with PATTERN DEF
The drill hole coordinates are stored in the
pattern definition PATTERN DEF POS and are called
by the TNC with CYCL CALL PAT:
The tool radii are selected so that all work steps
can be seen in the test graphics.
Program sequence
 Centering (tool radius 4)
 Drilling (tool radius 2.4)
 Tapping (tool radius 3)
