NOTE
The length from the tool tip to tool pivot point must equal the
sum of the tool length compensation amount and tool holder
offset value.
H : Offset number
G43.4 H_;
I,J,K : Tool axis orientation
H : Offset number
Q : Tool inclination angle (degrees)
G43.5 I_ J_ K_ H_ Q_;
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_.
G49 ;
The tool compensation vector changes in the following cases:
Type 1 : The offset value is changed, or the rotation axis position (B,
C) is specified.
Type 2 : The offset value is changed, or the tool axis orientation (I, J,
K) is specified.
As the tool compensation vector changes, movement is performed along
the X–, Y–, and Z–axes by an amount equal to the change. The time at
which the tool compensation vector is calculated is as follows:
Tool center point control : Calculated momentarily even in the middle
of a block.
Tool length compensation in tool axis direction: Calculated only at the
end point of a block.
