A Topological Mapping Grinding Strategy for Structured Groove Surface with the Wire-Wound Grinding Wheel

The structured groove surface is one of the important surfaces in the field of reducing fluid drag or contact friction. The research on the manufacturing technology of the structured groove drag or friction reduction surface has important theoretical significance and practical value for the engineering application of the theoretical research results of the drag or friction reduction of the surface. In order to grind structured groove surface, a new topological mapping grinding strategy for structured groove surfaces is innovated based on topology. In order to verify the feasibility of this strategy, the topological features of the structured groove surface were firstly analyzed and modeled, and the topological feature parameters were extracted. Based on the feature parameters, the homeomorphic mapping equation of the grinding process is established, and according to the established equation, a circular arc-shaped helical structure grinding wheel with convex properties is designed, and the effect of grinding parameters on the structured groove surface is simulated and analyzed. Finally, a wire-wound structured grinding wheel with a diamond wire saw as the abrasive carrier was manufactured, and the experimental investigation of grinding structured groove surface was carried out. The results show that the innovative topology grinding strategy is feasible; the grinding wheel designed based on the topological features of the structured groove surface can realize the topological mapping grinding of the structured groove surface; the change of grinding parameters can lead to the change of the geometric size of the groove, but the topological properties remain unchanged.
