The Tool Axis tab controls the orientation of the tool relative to the part when using the Four Axis Rotary strategy.
Use rotary Z tool — Select this option to align the tool with the Z axis of the active Setup.
Use rotary X tool — Select this option to align the tool with the X axis of the active Setup.
Specify angles — You can set the angle in one of these ways:
Index Angle — Enter the index angle to set the angle. If the angle is set to 0.0 then the tool is aligned with the X axis. The Index Angle is relative to the setup axis, just as it is with any feature alignment. The actual angle that is output in the code is relative to the stock axis.
B Angle — Enter an angle to set the B-axis angle.
Normal to surface — Set the angle as normal to the surface you pick using the Pick surface button. Optionally select Reverse direction.
