随着国民经济实力和科学技术水平的提高,社会日益强调提高产品的质量。在机械加工过程中,往往存在很多因素影响着工件的最终加工质量,而加工精度正是衡量零件加工质量的重要指标。因此,如何使工件加工达到质量要求、减少各种因素对加工精度的影响,就成为加工前必须考虑的事情;也就意味着,需要对影响机械加工精度的因素进行分析。 With the improvement of the national economic strength and the level of science and technology, the society has placed increasing emphasis on improving the quality of products. In the machining process, there are often many factors that affect the final processing of the workpiece quality, and processing accuracy is an important indicator of the quality of parts processing. Therefore, how to make the workpiece meet the quality requirements to reduce the impact of various factors on the machining accuracy, it has to be considered before processing things; also means that the need to analyze the factors that affect the machining accuracy.
