8.2 Program Defaults for Machining

Cycles

Overview

Machining cycles 20 to 25, as well as all of those with numbers 200 or
higher, always use identical cycle parameters, such as the set-up
clearance Q200, which you must enter for each cycle definition. The
GLOBAL DEF

function gives you the possibility of defining these cycle

parameters once at the beginning of the program, so that they are
effective globally for all machining cycles used in the program. In the
respective machining cycles you then simply link to the value defined
at the beginning of the program.

The following GLOBAL DEF functions are available:

Machining pattern

Soft key
