切削加工性

中文翻译
切削加工性(中文3500字,英文1800字)
1、一种材料的切削加工性通常从四个方面来定义：
(1)、已切削部分的表面光洁度和表面完整性。
(2)、刀具的寿命。
(3)、切削力和切削的功率需求。
(4)、切屑控制。
由上述可知，好的切削加工性指的是好的表面光洁度和完整性，长的刀具寿命，低切削力和功率需求。至于切屑控制，细长而卷曲的切屑，如果没有及时清理，就会在切削区缠绕，严重影响切削工序。
由于切削工序的复杂性，因此很难建立一个定量确定一种材料切削加工性的关系式。在制造厂里，刀具寿命和表面粗糙度通常被认为是切削加工性中最重要的影响因素。尽管切削性能指数使用的并不多，但基本的切削性能指数在下面的材料中仍然被使用。

英文原文
The machinability of a material
1. The machinability of a material usually defined in terms of four factors:
  1)、  Surface finish and integrity of the machined part; 
  2)、  Tool life obtained;
  3)、  Force and power requirements;
  4)、  Chip control.
Thus, good machinability good surface finish and integrity, long tool life, and low force and power requirements. As for chip control, long and thin (stringy) cured chips, if not broken up, can severely interfere with the cutting operation by becoming entangled in the cutting zone.
Because of the complex nature of cutting operations, it is difficult to establish relationships that quantitatively define the machinability of a material. In manufacturing plants, tool life and surface roughness are generally considered to be the most important factors in machinability. Although not used much any more, approximate machinability ratings are available in the example below.
