How to Program an Angle on a CNC Lathe Without CAM
Program a taper by hand with a straight G01 move to a computed X and Z endpoint. Use the tangent of the angle, and remember X is a diameter, not a radius.

Program a taper by hand with a straight G01 move to a computed X and Z endpoint. Use the tangent of the angle, and remember X is a diameter, not a radius.
A CNC lathe cutting a taper on a part that should be straight is usually a code error, tool or part deflection, or tailstock misalignment. Here is how to find which.
Taper turning in G-code is two diameters and a Z length: program both X ends and let G01 interpolate. The formulas, a worked example, and the comp trap.
