Prediction and analysis of cutting force coefficient of difficult materials based on response surface method
A prediction method for the cutting force coefficient of difficult-to-machine materials based on response surface method was proposed for the plane gantry to be cut with 300M materials,the significance of the prediction results was analyzed,and the influence of cutting parameters on cutting force coefficient and cutting force was explored.Based on the response surface method,the cutting force coefficient was expressed as a quadratic polynomial about the cutting parameters.By using the average cutting force coefficient identification model,the cutting force coefficient constants of 300M orthogonal experiments with different cutting parameters were obtained,the coefficients in quadratic polynomial function were obtained by multiple regression analysis,and analysis of variance and significance test were carried out.The cutting force coefficient and the response surface graph of cutting parameters were analyzed.The results showed that the regression function of 300M cutting force coefficient had high prediction accuracy and could be used to predict the cutting force coefficient under specific cutting parameters.The cutting width and feed rate per tooth have a great influence on the cutting force coefficient Ktc and Krc,and the cutting depth has a great influence on the cutting force coefficient Kac.
