DELDL - Delete sum offset
Sum offsets are generally only relevant when machining with a cutting edge at a certain time
at a certain location of the workpiece. You can use the NC language command DELDLto
delete sum offsets from cutting edges (in order to release memory).
status = DELDL( t, d )
If d is not specified, all sum offsets of all cutting edges of tool t are deleted.
If d and t are not specified, all sum offsets for the cutting edges on all tools of the TO unit are
deleted (for the channel, in which the command is programmed).
When working with setup offsets, the DELDL command deletes both the setup offset and the
"sum offsets fine" of the specified cutting edge(s).
Note
The memory used for the data sets is released after deletion.
The deleted sum offsets can subsequently no longer be activated or programmed.
Sum offsets and setup offsets on active tools cannot be deleted (similar to the deletion of D
compensations or tool data).
The "status" return value indicates the result of the deletion command:
0:
-1:
