金属材料的可切削性和刀具的切削性能是金属切削领域中的两个很主要的问题,但要评定金属材料的可切削性和刀具的切削性能,必须进行大量的切削试验,做出对比曲线,通过对比曲线来确定金属材料可切削性和刀具性能的好坏。但是用常规的方法来做对比曲线,需要消耗大量的金属材料和时间,尤其是对象铝合金、镁合金、低碳钢这样的易削材料,要使刀具磨损到磨钝标准(例如VB=0.3毫米),消耗的金属材料和时间就更长。为做出一条对比曲线
Metal machinability and tool cutting performance are two major problems in the field of metal cutting. However, to evaluate the machinability of metal materials and the cutting performance of the tool, a large number of cutting tests must be conducted to make a comparison curve , Through the comparison curve to determine the metal material machinability and tool performance is good or bad. However, using the conventional method to make the comparison curve requires a large amount of metal material and time, especially the easy-to-cut materials such as aluminum alloy, magnesium alloy and low carbon steel, and the tool wear to blunt standard (for example, VB = 0.3 Mm), the consumption of metal materials and time longer. To make a comparison curve
