The Effect of Grinding Force on the Surface Topography with the Structured Grinding Wheel
In order to improve the processing quality of the drag reducing riblet surface,the influence rule of grinding force of the grinding wheel with ordered abrasive pattern on workpiece surface geometry was studied.Firstly,according to the parameters of the drag reducing surface of the riblet surface,the staggered grinding wheel which can realize the surface machining of the riblet surface was designed.Secondly,a sim-plified model of the grinding process of the riblet surface is established,and the mechanical simulation of the workpiece surface topography was carried out based on the finite element method.Finally,the influences of grinding speed,grinding depth,abrasive angle and arrangement parameters on the surface geometry of the riblet surface was studied,and the relationship between grinding force and surface topography was com-prehensively discussed.The results showed that when the grinding speed increased,the material upheaval deformation height of the riblet surface increased with the decrease of the grinding force.When the grinding depth increased,the upheaval deformation height of the material increased with the increase of the grinding force.When the abrasive angle increased,the material upheaval deformation height increased first and then decreased with the increase of grinding force.When the configuration parameters increased,the material up-lift deformation height increased with the increase of the grinding force.
