Example: Using Drilling Cycles In Connection With Pattern Def - HEIDENHAIN TNC 620 User Manual

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.
