A Study on Optimization of Centerless Grinding 3h13 Steel

Round component with the minimum value of surface roughness and roundness error is the goal of most of the fine machine processes. This paper presents the research on optimization of plunge centerless grinding process when grinding the 3H13 steel to achieve the minimum value of surface roughness and roundness errors. The input parameters are center height angle of the workpiece, longitudinal dressing feed-rate, plunge feed-rate and control wheel velocity. Using the result of twenty-nine sets in central composite design matrix to show the two second orders of surface rounghness and roundness error models. The final goal of this work focuses on the determination of optimum centerless grinding above the parameters for the minimization of surface roughness (min:  0.8 µm) and roundness errors (min:  1.5 µm).
