怎样的切削速度属于高速切削,并没一个绝对的数量概念,而一直相对地定义为:“采用先进的刀具材料(主要指埂质合金或陶瓷刀具材料)而又能充分发挥其效能的切削,称为高速切削”。因此每当一种新型刀具材料出现,都会有一个相对高速切削的时期。金属切削加工发展的历史,也可以说,就是切削速度不断提高的历史,人们正是不断地采用新型刀具材料,克服了种种阻止切削速度提高的障碍,而使切削加工生产率得到飞速增长的。1906年美国工程师 F·W·泰勒(F·W·Taylor),发表了经过26年的调研和反复试验以后的著名论文“金属切削的技艺”,提出了迄今仍有重要意义的Vt~n=C 公式(Taylor 公式)。从图1中可知,该
What kind of cutting speed belongs to high-speed cutting, not an absolute quantity concept, has been relatively defined as: “The use of advanced cutting tool material (mainly alloy or ceramic cutting tool material) and can give full play to its effectiveness of cutting, Known as high-speed cutting. ” Therefore, whenever a new tool material appears, there will be a relatively high-speed cutting period. The history of the development of metal cutting, it can be said that the cutting speed continues to improve the history, people are constantly using new tool materials, to overcome all the obstacles to prevent cutting speed increase, making the cutting productivity growth rate. In 1906, American engineer FW Taylor published the famous paper “The Art of Metal Cutting” after 26 years of research and trial and error, and proposed the so far still important Vt ~ n = C formula (Taylor formula). As can be seen from Figure 1, this
