We have turned some different profiles using this system. By inputting a sinusoid into the actuator, non-circular parts are machined. Currently we are working to improve the system by incorporating the CNC Lathe's encorder signal so that the profile will can be a function of angular position, as in the above figure.
THe figures are highly exagerated so that the geomtrical differences can be seen. The actual differences between a true circle and the shapes shown is about 8 microns. The amount of deviation that can be achieved is dependant on the size of the actuator.
