Abstract:

It is beneficial for determining the process parameters quickly and improving the machining precision to set up a prediction model of cylindricity associated with honing process parameters. The experimental plan was designed by the method of quadratic general rotation union. Based on the experiments a prediction model of cylindricity was built, which was related with the stroke of honing tool, the pressure of honing, the rotary speed and the amount of finish. Analyzed with Design-Expert8.0 the prediction model was optimized. Quadratic response surfaces were given to exposing the relationship of the honing process parameters and the cylindricity of hole. And the optimized process parameters were decided. Some other experiments indicate that the prediction model is reliable, and the optimized process parameters are effective.
