机械加工MACHINABILITY

机械加工MACHINABILITY(中文3400字,英文1800字)
一种材料的机械加工性通常以四种因素的方式定义：
1、    分的表面光滑度和表面完整性。
2、刀具的寿命。
3、力量和功率的需求。
4、芯片控制。
以这种方式，好的机械加工性指的是好的表面光滑度和完整性，长的刀具寿命，低的力量和功率需求。关于芯片控制，细长的卷曲芯片，如果没有被切割成小片，以在芯片区变的混乱，缠在一起的方式能够严重的介入剪切工序。
因为剪切工序的复杂属性，所以很难建立定量地释义材料的机械加工性的关系。在制造厂里，刀具寿命和表面粗糙度通常被认为是机械加工性中最重要的因素。尽管已不再大量的被使用，近乎准确的机加工率在以下的例子中能够被看到。

MACHINABILITY
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.
