At present,the processing method of engineering ceramic materials mainly depends on diamond grinding wheel.The hard brittleness of SiC ceramics in traditional grinding process leads to the easy introduction of surface/subsur-face damage in grinding process,and the cutting force is large,the grinding wheel is worn seriously,and the material remov-al rate is low,which seriously restricts its wider application in modern industry.In order to solve the above problems,surface texture technology is used to assist the grinding process of SiC ceramics.The surface texture of SiC ceramic surface is abla-ted by millisecond pulse laser.The influence of laser surface texture parameters on the grinding performance of silicon car-bide ceramics is deeply studied.The results show that when the geometric parameters of texture depth and width are fixed,the lateral spacing of the texture has the greatest influence on the grinding force,and the larger the transverse spacing is,the greater the roughness value is.Compared to conventional grinding processing,the performance of laser-assisted grinding is improved,and the grid texture performance is better.
