When only the rotation axis position is specified in tool center point
control (type 1) mode, and when only I, J, and K are specified in tool
center point control (type 2) mode, the tool tip center position remains
unchanged before and after the specification. (Also, while the rotation
axes are being moved, the tool tip center does not move.)
For tool center point control (type 2), the inclination angle of the tool can
be specified with address Q of G43.5. The inclination angle of the tool
is the difference in the angle between the tool orientation specified by (I,
J, K) and the tool orientation set for actual machining.
If the tool orientation specified by (I, J, K) matches the tool orientation
set for actual machining, Q need not be specified.
Tool orientation specified by (I,J,K) Tool orientation during actual machining
Machining direction
Inclination angle of the tool
Example: For machining with the tool tilted toward the machining
direction by 2 degrees, specify the following:
G43.5 I_ J_ K_ H_ Q2.0
In programming, the position of the tool tip center is specified.
