CNC英文全名是：computerized numerical control。翻译过来就是：电脑数值控制（俗称数控）。它是现代工业机械加工的基础。应用电脑与机床的结合，依靠数字化定位原理来加工工件。能达到快速，准确，自动完成工件加工的目的。由于定位精准，人工干预少，重复性好而广泛应用在很多的行业。机械加工是CNC里面的一小部分。

The machining accuracy is refers to the size related work has in the processing is completed. The actual geometry and the mutual position of the surface parameter value, degree of correspondence and pre design ideal geometry parameters on the demand. The machining accuracy usually include dimensional accuracy. The shape accuracy and position accuracy, content, range size precision machined surface with reference to limit the size error, the shape precision is used to limit the surface macro geometry error, position accuracy is used to limit the processing surface and reference the parallelism between each other. The verticality coaxial position error. Because of the performance of processing machinery. Technology and methods. Effects of different production conditions and other factors, the related parts processing machinery in its size. The shape and surface position parameters and the ideal parameters deviation error always exists, to represent the machining accuracy is usually used in the numerical size of the machining error. Mechanical components machining accuracy and surface quality of machining quality. Is the basis for mechanical product assembly quality, processing errors reflect the size of the processing precision.
