To improve design methodology of abrasive tool manufacturers, the CAD/CAM integrated system of the resin-bonded abrasive tool was designed and developed for small and medium-sized enterprises. The manufacturing process of the resin-bonded abrasive tool was described. Then overall architecture and specific function modules of the CAD/CAM integrated system were designed. The CAD/CAM integrated system of resin-bonded abrasive tool was developed based on C#.NET platform. The design efficiency and level of resin-bonded abrasive tool in small and medium-sized enterprises can be enhanced based on the proposed integrated system.
