金属薄板的r,n值及其测定

The r,n Value of Sheet Metal and Their Measurement

本文阐述了测定 r、 n 值在研究金属薄板冲压性能和冲压生产中的意义;分析了影响 r、n 值测定精度的因素,并从试样加工、试验方法、数据采集和数据处理等方面提出了提高测定精度的途径.

States the siginificance of the measurement of r,n value in stiadying the properties and production of stamping,analyzes the factors related to the precision of r,n value.Gives the approach to go up the measuring precision on the aspects of sample-preparing,experimental methods,data-collecting and processing.
