定位误差分析计算是机床央具设计与制造过程中的难点之一，而定位基准的正确选择及合理应用是提高加工工件制造精度的重要途径。在夹具设计中，V型块是常用的定位元件．根据所加工零件的具体要求．采用不同定位方式会产生不同的定位误差，从而直接影响到加工精度。现就本公司生
Positioning error analysis and calculation is one of the difficulties in the design and manufacture of the machine tool center. The correct choice and reasonable application of the positioning datum is an important way to improve the manufacturing accuracy of the workpiece. In fixture design, V-blocks are commonly used positioning elements. According to the specific requirements of the processed parts. Using different positioning methods will produce different positioning errors, which will directly affect the machining accuracy. Now on the company students
