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.
As
active, the values in
B45 is 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. 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.
N280 defines a rotation in accordance with the rotation of the table of the toolholder with
orientation capability. The new X direction thus points in the direction of the bisecting line in
the 4th quadrant, the new Z axis in the direction of the bisecting line in the 1st quadrant.
The zero point is approached in N290, i.e., the machine position X10.607 Y0 Z-4.393, since
the position of the zero point is not changed by the rotation.
N300 traverses in Y to the position Y33.000, since G18 is active and the Y component is not
affected by the active frame. The X and Z positions remain unchanged.
The position X17.678 Y0 Z1.536 is approached in N310.
