| Abstract: | Considering the developed CNC lathe prototype of theory,which is based on noncircular in cross-section,it analyzed the latticing theory of elliptical cross-section,practically cutted the elliptical cross-section with PMAC time based controlling.The results proved that the linear motor servo driving system can accurately follow the high speed revolving of spindle by reasonable adjusting the parameters of controlling algorithm,which is based on PID + velocity and acceleration feedforward of PMAC,lattice out e... |
