- 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 from the direction
specified by (I, J, K) 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.)
Generally, 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 from the normal
direction, 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.
