Tool offsets
8.2 Language commands for tool management
Example of the GETSELT function
This function returns the T number of the tool preselected for the spindle. This function
allows access to the tool offset data before M6 and thus establishes main run
synchronization slightly earlier.
Example of tool change using tool management
T1:
Tool preselection; i.e. the tool magazine can be put in tool position parallel to the machining.
M6:
Changing to a preselected tool (depending on default setting in the machine data it may also
be programmed without M6).
