Research of the special numerical control system of CNC spinning machine

In order to solve the problems of our head spinning craft unable to realize automation,serialization,high precision and the best surface quality,the open numerical control technology was applied to the head spinning machine.After analysis of spinning trajectory planning based on the head spinning force model,the connection between spinning mathematical model and the head spinning machine CNC system was established,and the method of the open systems development based on the industrial personal computer(IPC) and motion control card was presented.The spinning machine CNC system had made full use of the rich software resources on the Windows system and Visual C++6.0.The building CNC system was tested and evaluated.The experimental results show that the CNC system is stable,and it realizes the overall design requirements.
