数控是先进制造技术的基础技术。数控加工在现代化生产中显示出很大的优越性。
对于现代制造业,数控机床非常适合那些形状复杂、精密和批量小的零件。而一般的普通机床根本无法满足这个要求。就连仿形机床和组合机床也解决不了高精度与小批量这个矛盾。因此数控加工非常适合航空、航天、电力、交通和电子等制造业的零件加工技术。
零件加工面临的一个主要问题是产品的高精度、多样性和批量小的矛盾。这就要求从机床到数控都需要柔性。CNC数控系统由于采用软件控制,具有了很大的柔性。
现代的数控机床其突出的优点是可以进行高精度加工和多样化加工,完全可以取代其他的加工方法。由于数控机床是按照预定的程序自动加工,加工过程不需要人工干预,加工精度还可以通过软件进行校正及补偿,因此可以提高零件的加工精度,稳定产品的质量。特别对于多品种、少批量的零件更是如此。

Abstract
NC advanced manufacturing technology is the basis of technology. NC in the modernization of production showed great superiority.
To the modern manufacturing, numerical control machine tools suitable for those who shape very complex, sophisticated and small quantities of parts. And general general machine tools simply can not meet this requirement. Even the copying machine and the combination of high precision machine tools can resolve them with small quantities this conflict. So NC is very suitable for aviation, aerospace, power, transport and manufacturing parts such as electronic processing technology.
Parts processing facing a major problem is the high-precision products, diversity and small quantities of contradictions. This requires from all of CNC machine tools to the need flexible. Because of CNC systems using software control, with a lot of flexibility.
Modern CNC machine tools highlight the advantages of high-precision processing can be carried out and diversification of processing, can replace the other processing methods. As According to the NC machine tools is the automatic processing procedures, the process does not require manual intervention, processing accuracy can be corrected by software and compensation, so parts of the processing can improve the accuracy, stability, the quality of the products. Particularly for multi-species, especially small quantities of parts.

Key words: CNC Technology, Huazhong century-HNC-21, cutter models, cutting the amount, manual programming
