Machining aims to generate the shape of work-piece from a solid body, or to improve the tolerances and surface of a previously formed work-piece , by removing excess materials in the form of chips.

旨在产生加工工件的形状,从一个实体或提高公差和表面形成以前的工件,通过切除多余物质形式的筹码。

Machining is capable of creating geometric configurations ,tolerances ,and surface finishes often unobtainable by any other technique.

他能创造加工的几何构型,公差,表面镀层往往难以获得的任何其它的技术。

However, machining removes materials, which has already been paid for ,in the form of relatively small particles that are more difficult to recycle and are in greater danger of becoming mixed.

然而,加工去除材料,已支付的形式),相对小的粒子,更难以回收和在更大的危险成为混合。 Therefore , developments often aim at reducing or if at all possible-eliminating machining , especially in mass production .
