1、 解决造成刀具磨损问题办法高速切削理论由德国物理学家 Carl.J.Salomon 在上世纪三十年代初提出的。他通过大量的实验研究得出结论：在正常的切削速度范围内，切削速度如果提高，会导致切削温度上升，从而加剧了切削刀具的磨损；然而，当切削速度提高到某一定值后，只要超过这个拐点，随着切削速度提高，切削温度就不会升高，反而会下降，因此只要切削速度足够高，就可以很好的解决切削温度过高而造成刀具磨损不利于切削的问题，获得良好的加工效益。High speed cutting theory by the German physicist Carl. J. alomon in the early 1930
