Application of Generalized Reduced Gradient Method for Optimization of Plunge Centerless Grinding Process
Keywords:
Plunge centerless grinding, optimization, generalized reduced gradient, surface roughness, 20X steelAbstract
This paper presents the study on optimization of plunge centerless grinding parameters when grinding 20X – carbon infiltration steel (ГOCT standard - Russia) to achieve minimum of surface roughness value by generalized reduced gradient method. Using the result of 29 runs in central composite design matrix with input parameters are center height angle of the workpiece ( ), longitudinal grinding wheel dressing feed-rate ( ), plunge feed-rate ( ) and control wheel velocity ( ) to given the second order surface roughness model. Using generalized reduced gradient method to get optimization values of input parameters to achieve minimum of surface roughness.
