I have used the "Contour Toolpath", "Rotation Axis", "Axis Substitution" and "Substitute Y axis" for machining before, there is no problem.

Now because the work piece's diameter is too big, I therefore must face the work piece axle center to Z axis and uses aggerate head to let the cutting tool's direction as right side view for machining, but there is a problem that the axis substitution has not substituted for the Z axis. Is there any solution for this problem?

Look no emastercam I put the answer over there as well. You need to change the rotary axis in the machine definition manger to be rotating around the Z axis not the X axis if you want the ability to use the Z for axis mapping. If your axis is rotating around X then you will not have the option to use Z only X and Y since that is the only 2 available axis for that set-up anyway.
