Lathe Speed Control – G96 Constant Surface Speed

The lathe as we know, is different than a mill in the simple fact that with a lathe, our part is what rotates and our tool is what stays steady. Because of that we need to calculate our speed and feeds based of the rotation of the part. Cutting Speed (SFPM) = (Spindle RPM X Cut Diameter (in.)) / 4 …
