The figure below shows handle pulse (Hp) distribution to the X–axis,
Y–axis, and Z–axis for each of the four directions.
(1) A–C axis type (X–axis direction)
Xp = HpCOS (C)
Yp = HpSIN (C)
Zp = 0

The XY plane is drawn be-
cause A– and C–axes are spe-
cified and because rotation
about the A–axis, which is on
the X–axis, does not cause the
tool to rotate about the X–axis
at the tool tip. Suppose that
the Z–axis on this side of the
XY plane is positive.
