Program defaults for cycles
Overview
All 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 at the beginning of the program, so that
they are effective globally for all machining cycles used in the
program. In the respective machining cycle you then simply link to
the value defined at the beginning of the program.
The following GLOBAL DEF functions are available:
Soft key
Machining patterns
GLOBAL DEF COMMON
Definition of generally valid cycle
parameters
GLOBAL DEF DRILLING
Definition of specific drilling cycle
parameters
GLOBAL DEF POCKET MILLING
Definition of specific pocket-milling
cycle parameters
GLOBAL DEF CONTOUR MILLING
Definition of specific contour milling
cycle parameters
GLOBAL DEF POSITIONING
Definition of the positioning behavior
for CYCL CALL PAT
GLOBAL DEF PROBING
Definition of specific touch probe
cycle parameters
Entering GLOBAL DEF
Operating mode: Press the Programming key
Press the SPEC FCT key to select the special
functions
Select the functions for program defaults
Press the GLOBAL DEF soft key
Select the desired GLOBAL DEF function, e.g. by
pressing the GLOBAL DEF GENERAL soft key
Enter the required definitions, and confirm each
entry with the ENT key
