CNC spinning machine is similar to a conventional lathe with some differences in its operation. The motions in the longitudinal and transverse axes are synchronized to generate two-dimensional tool path for producing spun components. Lead screws motions are obtained using separate motors. A mandrel is...

With active control of the speed of the main drive, the dynamic state often associated with machine-tool vibrations can be avoided. Many researchers have also studied the impact of cutting speed on surface roughness, cutting forces, and tool life in turning operations using experimental and ...
