Multi-objective genetic optimization on matrix structure of ultra-high speed grinding wheel

In order to control expanding deformation in ultra-high speed grinding and reduce the rotation stress,the matrix of grinding wheel is optimized.Based on the analysis of cross section of the matrix,the parameterized model of grinding wheel matrix is established by straight line and spline curve and thus the multi-objective genetic optimization of grinding wheel matrix is realized.The results show that under grinding speed of 250 m/s,expansion deformation and equivalent stress of the optimized grinding wheel matrix respectively decrease to 30.827 μm and 94.97 MPa.Comparing with the original grinding wheel they are respectively reduced by 25.67% and 6.44%.
