The Angular (Move menu) command is used to position the rotary axes to know angles. See B-axis Angular Convention
One rotary axis can be moved at a time.

The command is available when a driven tool is selected. Currently it is not available when a turning tool is selected.
While moving the C-axis it is possible also to move the linear XYZ axes. The XYZ coordinates are relative to either the machine datum or the currently selected spindle CPL.
Note
Planar mode is automatically forced when the b-axis not at 0, 90 or 180 degrees. In planar mode, milling is performed with the C-axis fixed.
When selecting a turning tool or fixed milling tool the active CPL automatically reverts back to the last used spindle turn CPL.
Coord System is only available in CY Turning.
