機械(xie)加(jia)工是指通過一種(zhong)機械(xie)設(she)備(bei)對(dui)工件的外(wai)形尺寸(cun)或性能進行改變的過程。按加(jia)工方式上的差(cha)別可分(fen)為切削加(jia)工和壓力加(jia)工。

生產(chan)類型通(tong)常分(fen)為三類：

1．單(dan)件(jian)生產(chan)：單(dan)個(ge)地生產(chan)不同結構和(he)不同尺寸(cun)的產(chan)品(pin)，并(bing)且很少(shao)重復(fu)。

2．批量生產(chan)：一年中分批地(di)制造(zao)相同的產(chan)品(pin)，制造(zao)過(guo)程有一定(ding)的重復性。

3．大批量(liang)生產(chan)：產(chan)品的制(zhi)造數量(liang)很大，大多數工作(zuo)地點經(jing)常是重(zhong)復(fu)進行某一個零件的某一道工序(xu)的加工。

Machining refers to the process of changing the shape size or performance of the workpiece through a mechanical device. According to the difference in processing methods, it can be divided into cutting and pressure processing.
Production types are usually divided into three categories:
1. Single-piece production: individual production of products of different structures and sizes, and rarely repeated.
2. Mass production: The same products are manufactured in batches throughout the year and the manufacturing process is somewhat repetitive.

3. Mass production: The product is manufactured in large quantities and most duty stations often repeat the processing of a particular part.
