Processing toolholder data blocks
Two options are available:
• Explicit entry in the toolholder data block from the part program
• Automatic acceptance of certain values (angles) from a frame
A requirement for this is that TCOFR (Tool Carrier Orientation FRame) is also specified when the toolholder is
selected.
The tool orientation used to calculate the tool length is determined again from the frame active at this time
when a toolholder is changed.
