中间公差加工法的工艺研究

Research on the Technique of Method of Middle Tolerance Machining

采用"中间公差加工法"在机加工生产中可以使工件的加工尺寸围绕公差的中心呈正态分布,显著地提高工程能力等级,从而保证产品的加工质量。

Using method of middle tolerance machining in mechanical production , we can make machining size of workpiece distribute normally around the centre of tolerance. The grade of engineering ability can be greatly increased. The machining quality of products will be improved.
