摘　　要：面向一切削加工系统,通过切削试验,以切削面积刀具的相对磨损值为量值,提出了基于最佳切削温度下切削用量的确定方法。首先,从铣削加工试验中获取切削速度与切削表面积相对磨损值和切削温度的关系,研究了最优切削用量与切削温度的关系;然后,通过刀具磨损现象,探讨了最佳切削温度时刀具磨损的机理;最后,建立了切削用量的优化方程。从而为切削用量的优化探索了新的途径,为金属切削数据库的建立提供了依据。Based on the best machining temperature,with the help of cutting experiment,taking the ratio that the value of cutting-tool wear divided by surface area machined on workpiece surface as an evaluating level,a method defining cutting parameters was presented in a manufacturing condition for milling.Firstly,the relationships between cutting speeds and temperatures,the ratios above mentioned,were gained from the experiments.And the relationship between the optimal cutting parameters and temperatures were described.Then,the mechanics of cutting-tool wear at the best cutting temperature was analyzed through the status of its wear.Finally,the optimal equation of the cutting parameters was established.So a new approach to optimize cutting parameters was studied.Further a basic governing was also provided for construction of a cutting database of metal materials.
