工件组合定位和定位误差的研究

Research on the Combined Positioning and Positioning Error of Workpiece

工件定位的意义在于其相对于机床、刀具占有正确的位置,为机械加工做好准备。工件在定位中产生的误差,是零件加工误差的根源。因此,深层次地了解定位误差的分析方法,掌握工件各种加工方案中定位误差的计算方法,是加工合格零件的途径之一。

The significance of workpiece positioning is that it has the correct position relative to the machine and the cutting tool. The error caused by the positioning of the workpiece is one of the major sources of machining error, Therefore, one of the ways to process the qualified part is to understand the analysis method of the positioning error and to master the calculation method of the positioning error.
