The definition of the toolholder with orientation capability is given in full.
The components that contain the value 0 need not actually be given, as they are preset to
zero in any case.
The toolholder is activated in N270.
As
active, the values in
A0 B45 is used for the rotation.
The rotation of the 4th offset vector (length 15 mm in Z direction) about the B axis
causes an offsetting of the zero point by X10.607 [= 15 * sin(45)] and
Z-4.393 [= -15 * (1. - cos(45))].
This zero offset is taken into account by an automatically written basic or system frame so
that the position X10.607 Y10.000 Z8.607 is approached. In the Z direction the tool selection
leads to an additional offset of 13 mm; the Y component is not affected by the table rotation.
