Research on Optimization of Plunge Centerless Grinding Process Using Genetic Algorithm and Response Surface Method

This paper presents the research on optimization of plunge centerless grinding process when grind 20X-carbon infiltration steel (ΓOCT standard-Russia) to achieve minimum of roundness error value. The input parameters are center height angle of the workpiece (β), longitudinal grinding wheel dressing feed-rate (S_sd), plunge feed-rate (S_k) and control wheel velocity (V_dd). Using the result of 29 runs in Central Composite Design matrix to given the second order roundness error model. Genetic algorithm and Response surface method were used to focus on determination of optimum centerless grinding above parameters for minimization of roundness error for each methods.
