NC FUNCTION

G43.4 H_;
H : Offset number
G43.5 I_ J_ K_ H_ Q_;
I,J,K : Tool axis orientation
H : Offset number
Q : Tool inclination angle (degrees)
NOTE
1 When I, J, and K are all omitted from a block, the
compensation vector in the previous block is used.
2 When any of I, J, and K is omitted, the omitted I, J, or K is
assumed to be 0.
3 Movement of the rotation axes is controlled by shortcut
control so that the amount of movement does not exceed
180.

The rotary table dynamic fixture offset function saves the operator the
trouble of re–setting the workpiece coordinate system when the rotary
table rotates before cutting is started. With this function the operator
simply sets the position of a workpiece placed at a certain position on the
rotary table as a reference fixture offset. If the rotary table rotates, the
system automatically obtains a current fixture offset from the angular
displacement of the rotary table and creates a suitable workpiece
coordinate system. After the reference fixture offset is set, the workpiece
coordinate system is prepared dynamically, wherever the rotary table is
located.
The zero point of the workpiece coordinate system is obtained by adding
the fixture offset to the offset from the workpiece reference point.
G54.2 Pn ;
Pn : Reference fixture offset value number (1 to 8)
If n is set to 0, the fixture offset becomes invalid.
