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
$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) 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.
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.
