Program defaults for cycles

2.2 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 once at the beginning of the program,
so that they are effective globally for all fixed cycles used in the
program. In the respective fixed cycle you then simply link to the
value defined at the beginning of the program.
The following GLOBAL DEF functions are available:
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
