Research of force drives of the production gear hobbing machine with CNC

Abstract

The method of speeding up the time of cutting in and cutting off processes in forced gear hobbing with the CNC gear hobbing machine is proposed. The method is based on corresponding control of the axial feed axis by creation of the pulse type axial feed during these processes and corresponding control of shifting axis. For modeling of the cutting process, the dynamic model and on the base of it the diagram for simulation and investigation of control methods were created and are presented here. The model created allows researching force, accuracy and control dependences. Examples of force drives modeling are shown, as well.
