The definition of the toolholder with orientation capability is given in full. The components which
contain the value 0 need not actually be given, as they are preset to zero in any case.
The toolholder is activated in N270.
$TC_CARR21 and $TC_CARR22 refer to the machine axes A and B and TCOABS is active,
As
the values in
used for the rotation.
The rotation of the 4th offset vector (length 15 mm in Z direction) around 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.
