In the field of machining industry, the precision size control of the drawing plays an important role, which directly affects the assembly performance and quality of mechanical equipment. And precision machining of the main factors influencing size is error, due to the error problem is influenced by many factors, the machine precision machinery processing error will inevitably appear all sorts of problems, so only used in a variety of technical measures, the accuracy control in the range of a science. This requires technicians to strictly follow the production drawing process and strictly require the mechanical process flow, so as to ensure the precision of the precision machined production drawing.

　 在社会经济以及工业改革飞速发展的今天，精密机械加工所扮演的角色已经越来越重要了，而我国机械加工行业也取得了很大的进步，不仅质量得到了极大的提升，在生产规模上也大大的扩展了。而随着工业化进程的发展，对于精密机械加工的精度问题也越来越重视，因此，一定要加强机械加工过程中对精度的控制（精密机械加工的过程中，对于精度的控制问题必须十分重视，并且针对出现的问题采取合理的技术措施解决。

In the rapid development of social economy and industrial reform today, the role of the precision machining has been more and more important, and the machining industry in our country has made great progress, not only greatly improve the quality, on the scale of production is also greatly expanded. But with the development of the industrialization process, for precision machining accuracy problem is becoming more and more attention, therefore, must strengthen in the process of machining of precision control (precision machining process, the precision of the control problem must attach great importance to, and to take reasonable technical measures to solve the problems of.

　　国内的机械加工领域，对于机械加工的精度有着明确的定义，它指的是专业的技术人员在机械零件加工完成以后，利用仪器对零件的位置$形状、尺寸以及相关的数据进行检测，从而确定零件的符合程度。一般来说，对机械加工精度造成影响的主要因素是机械加工中产生的各种误差，技术加工的操作人员以及技术单位必须对此问题十分重视。在机械加工中对于精度的控制以及把握与机械加工的误差问题相比，有着十分明显的联系。机械加工的误差主要是通过形状、尺寸以及位置来体现的，它是通过利用对机械尺寸的控制来达到控制机械加工精度的目的，在保证机械加工的表层质量的时候，将机械加工的尺寸误差控制在一个合理的范围之内。在机械加工的过程中，由于受到基准以及加工表层的影响，会造成精密零件位置的偏差，因此，对于精密机械加工的垂直度$同轴度、位置度以及平行度，一定要严格的进行控制。

Domestic mechanical processing field, the machining accuracy has a clear definition, it refers to the professional and technical personnel in mechanical parts processing is complete, using the instrument for the location of the parts $shape, size and related data for testing, to determine the parts conform to the degree. In general, the main factors that affect machining accuracy is produced by various error in mechanical processing, technical processing of operating personnel and technology unit must attach great importance to this problem. The control of precision and the error of machining are very obvious in machining. Machining error is mainly through the shape, size and position to reflect, it is through the use of mechanical size control to achieve the purpose of control machining precision, at the time of guarantee the quality of machined surface, the size of the machining error control in a reasonable range. In the process of mechanical processing, due to the benchmark and the influence of the processing surface, can cause precision parts position deviation, therefore, the precision machining of verticality $coaxial degree, location, degree and parallel degree, must be strictly controlled.
