Alternative typical table - table machine tools angular limits are:
X 100
Y 360
This translates to Azimuth Angle limits of 0 to 360 and to Elevation Angle limits of -10 to 90.
The machine tool's X angle range = 100, PowerMill's elevation angle range = -10 to 90.
If you select a Mode of Remove Toolpath, this machines:
