可機(jī)加工性
一種材料的可機(jī)加工性通常以四種因素的方式定義：
1、分的表面光潔性和表面完整性。
2、刀具的壽命。
3、切削力和功率的需求。
4、切屑控制。
以這種方式，好的可機(jī)加工性指的是好的表面光潔性和完整性，長(zhǎng)的刀具壽命，低的切削力和功率需求。關(guān)于切屑控制，細(xì)長(zhǎng)的卷曲切屑，如果沒(méi)有被切割成小片，以在切屑區(qū)變的混亂，纏在一起的方式能夠嚴(yán)重的介入剪切工序。
因?yàn)榧羟泄ば虻膹?fù)雜屬性，所以很難建立定量地釋義材料的可機(jī)加工性的關(guān)系。在制造廠里，刀具壽命和表面粗糙度通常被認(rèn)為是可機(jī)加工性中最重要的因素。盡管已不再大量的被使用，近乎準(zhǔn)確的機(jī)加工率在以下的例子中能夠被看到......



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 ......
