不同的定位方式对工艺质量有相当重要的影响,而基准位移和基准不重合作为产生定位误差的重要因素,在定位方式选择上应优先考虑;以阶梯孔零件加工为载体,建立对比数学模型,采用定位理论分析、实践数据分析、误差改进设计等方法,从误差的来源、影响程度、定位方式选择、误差计算到定位改进对此问题进行探讨,达到降低误差影响,提高工艺质量的目的。
Different positioning methods have a significant impact on the quality of the process, and the benchmark displacement and the benchmark do not coincide as an important factor in positioning error, positioning method should be given priority to; ladder hole parts processing as a carrier, the establishment of mathematical models, Positioning theory analysis, practice data analysis, error improvement design and other methods, from the source of the error, the impact of degree, the choice of positioning methods, error calculation to improve the positioning of this issue to achieve the purpose of reducing the impact of errors and improve the quality of the process.
