Study on the Turning Technology of the Thin Cylinder of Carbon Fiber

This paper analyses and researches the technological methods of the thin walled cylinder of carbon fiber reinforced plastics.The influence of processing characteristics and cutting vibration has been analyzed by experiment for the work pieces.Special mechanism for champing and positioning was developed, at the same time choice of geometry technical parameters and materials were experimentally determined.Orthogonal experiments were used to make sure the optimal cutting parameters,verified the feasibility of the process through experiments.Cracked the key technical difficulties such as wire drawing,burrs and the deformation of champing and machining.It had made significant effect to apply the processing technology to the production.
