Research on Positioning Accuracy Retentivity of Machining Center Based on Residual Stress

Ma Wenshuo;Mi Jie;Yang Qingdong;Beijing Information Science & Technology University;  
The relationship between residual stress and the positioning accuracy retentivity of machining center was conducted.Then a new method for quantitative analysis of positioning errors caused by residual stress was proposed.Following the analyses of the processes which produced residual stress,residual stress analyses were carried out on a domestic cartridge receiver machining center bed by using finite element method.Thus the distribution of the residual stress of the bed after casting process and machining process was obtained.Then the deformation of the joint surface between the bed and guide was predicted,which was verified by being compared with the actual measurement.Finally,positioning errors caused by residual stress were calculated.
