- Inclination angle of the tool
In the case of tool center point control of type 2, the inclination angle of the
tool can be specified using address Q of G43.5. The inclination angle of
the tool represents how inclined the tool direction is toward the proceeding
direction with respect to the direction specified by (I, J, K) at the time of
machining on the plane produced by the tool direction specified by (I, J, K)
and the proceeding direction on the programming coordinate system. (See
the figure below.)
Overviewly, the normal direction on the machining plane is specified by (I, J,
K). If the tool direction needs to be inclined toward the proceeding
direction with respect to the normal direction at the time of machining,
perform compensation using Q.
If the direction specified by (I, J, K) matches the direction in which the tool
moves at the time of machining, commanding Q is unnecessary.
