DWELL TIME (Cycle 9)
Application
Within a running program, the execution of the next block is delayed by
the programmed dwell time.
The dwell time can be used for chip breaking, for example.
Activation
The cycle becomes effective immediately upon definition. Modal con-
ditions such as spindle rotation are not affected.
Input data
The dwell time is entered in seconds.
Input range: 0 to 30 000 seconds (approx. 8.3 hours) in increments of
0.001 second.
PROGRAM CALL (Cycle 12)
Application and activation
Routines that are programmed by the user, such as special drilling cycles,
curve milling or geometrical modules, can be written as main programs
and then called for use like fixed cycles.
Input data
Enter the file name of the program to be called.
The program is called-up via
• CYCL CALL (separate block) or
• M99 (blockwise) or
• M89 (modally).
Example: Program call
A callable program 50 is to be called into a program via cycle call.
