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

Cardan toolholder with two axes
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.
Basic logic functions: Tool Offset (W1)
