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
$TC_CARR21
and
$TC_CARR22
refer to the machine axes A and B and TCOABS is
active, the values in
$TC_CARR13
and
$TC_CARR14
are ignored, i.e., the axis position
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.
