(3) Start-up with movement command (When rotary axis command is issued in the same block)
(a) Tool center point control type1
In the case of using the tool tilt type, the orthogonal axis moves according to the rotary axis
angle while fixing the tool center point to the center. In the case of using the table tilt type,
the orthogonal axis moves so that the tool center point locates on the rotated table
workpiece coordinate system.
