Tool orientation
Depending on the orientation direction selected for the tool, the active working plane (G17,
G18, G19) must be set in the NC program in such a way that tool length offset works in the
direction of tool orientation.
Note
When the transformation is enabled, the positional data (X, Y, Z) always relates to the tip of
the tool. Changing the position of the rotary axes involved in the transformation causes so
many compensating movements of the remaining machine axes that the position of the tool
tip is unchanged.
Orientation transformation always points from the tool tip to the tool adapter.
