In order to grind the riblet surface for drag reduction with the grinding wheel with ordered abra-sive pattern,firstly,the relationship between the abrasive ordered grinding wheel parameters and the depth-width ratio of the ground riblet surface for the drag reduction is analyzed,The geometry model and mathe-matical model of the grinding wheel with ordered abrasive pattern are designed,The motion path equation of abrasive is established;Then,the mathematical equations between the depth-width ratio of the riblet sur-face for the drag reduction and the arrangement parameters of the ordered grinding wheel are established;Finally,the influence of arrangement parameters of grinding wheel on the surface morphology and depth-width ratio of the riblet surface for drag reduction.The results show that the change of inclination angle,distance between abrasive and grinding depth has a direct influence on the size of the riblet surface for drag reduction and plays a decisive role in the depth-width ratio of the riblet surface for drag reduction.
