Abstract： A potential, rapid and accurate technique to determine r value of deep drawing steel sheet was investigated. The pole figure data which should be measured are reduced drastically because of the pole figure symmetry and collected holistically by the X ray area detectors, then the volume fraction of texture components in Gaussian form is obtained. According to such volume fraction, the r value of steel sheets can be calculated rapidly and accurately by the plastic deformation model, meanwhile some other effecting factors beside texture are also included. The rapid and accurate determination technique could be applied to the online r value determination of deep drawing steel sheet.
