When a 5–axis machine that has two axes for rotating the tool is used, tool
length compensation can be performed in a specified tool axis direction
on a rotation axis. When a rotation axis is specified in tool length
compensation in tool axis direction mode, tool length compensation is
applied in a specified tool axis direction on the rotation axis by the
compensation value specified in the H code. That is, movement is made
along the three linear axes (Xp, Yp, Zp).
Unless otherwise noted in the explanation of this function, the two
rotation axes are assumed to be the B–axis and C–axis.
