DWELL TIME G04
Application
Within a running program, the execution of the next block is delayed by
the programmed dwell time.
A dwell time cycle can be used, for example, for chip breaking.
Activation
This cycle becomes effective as soon as it is defined. Modal conditions
(such as spindle rotation) are not affected.
Input data
The dwell time is programmed with G04 followed by F and the desired
dwell time in seconds.
Entry range: 0 to 30 000 s (approx. 8.3 hours) in increments of 0.001 s.
Example NC block: N135 G04 F3 *
PROGRAM CALL G39
Application and activation
Part programs such as special drilling cycles, curve milling or geometric
modules, can be written as main programs and then called for use just like
fixed cycles.
Input data
Enter the file name of the program to be called.
The program is called with
• G79 (separate block) or
• M99 (blockwise) or
• M89 (modally)
Example: Program call
A callable program (program 50) is to be called into a program with a cycle
call.
Part program
G39 P01 50 ................................................................. Definition: "Program 50 is a cycle"
G00 G40 X+20 Y+50 M99 .......................................... Call of program 50
