10.6.5 Subroutines
If you require the same machining steps when programming different workpieces, you can
define these machining steps in a separate subprogram. You can then call this subprogram
in any program.
Identical machining steps therefore only have to be programmed once.
A distinction is not made between the main program and subprograms. This means that you
can call a "standard" ShopMill or G code program in another ShopMill program as a
subprogram.
You can also call another subprogram in the subprogram. The maximum nesting depth is 15
subprograms.
Note
You cannot insert subprograms into linked blocks.
If you want to call a ShopMill program as a subprogram, the program must already have been
calculated once (load or simulate program in the "Machine Auto" mode). This is not necessary
for G code subprograms.
Program clipboard
If you use the "Execution from external storage (EES)" software option, the subprogram can
be stored locally or externally in an arbitrary program memory configured for EES.
If you use the "CNC user memory extended" software option, the subprogram can be stored
on the system CF card in a program memory configured for EES.
Without these two software options, the subprogram must always be stored in the NCK work
memory (in a separate "XYZ" directory or in the "Subprograms" directory). If you still want to
call a subprogram located on another drive, you can use G code command "EXTCALL".
Program header
Please note that when a subprogram is called, the settings in the program header of the
subprogram are evaluated. These settings also remain active even after the subprogram has
ended.
If you wish to activate the settings from the program header of the main program again, you
can make the settings again in the main program after calling the subprogram.
Procedure
1. Generate a ShopMill or G code program that you wish to call as a sub‐
program in another program.
2. Position the cursor in the work plan or in the program view of the main
program on the program block after which you wish to call the subpro‐
gram.
