齿轮高速干切滚刀寿命预估模型与优化方法
High-speed Dry Gear Hob Life Prediction Model and Optimization Method
摘要
Abstract
Because high-speed dry hobbing technology lacked cutting oil and lubrication for cooling under high cutting speeds,the high-speed dry gear hob should have very high cutting properties including good wear resistance,high temperature resistant which led to a complex and expensive manufacturing for the substrate material and coating of high-speed dry hobs.Therefore,it was necessary to optimize the high-speed dry hobbing technology to improve the hob tool life to reduce manufacturing costs and improve efficiency.Combining the experiments in production practices and theoretical analysis,the failure modes and wear principles of the high-speed dry hobs were analyzed.The cutting lengths of single blade were used as evaluation indexes of the high-speed dry hob tool life and the corresponding calculation model was established.Based on this calculation model'high speed dry hob life experiments were carried out in gear production line.In order to build the empirical formula for hob tool life,a multivariate linear regression model which solved by MATLAB was established.Based on these work,a way to optimize processing parameters and a new hob shifting strategy were put forward to improve high speed dry hob tool life.关键词
