Notes:
This paper proposes a sub-aperture grinding tool for loose abrasive computer controlledsurfacing, which is designed to perform epicyclic motion and rotate around its centre at a rapid rate,whilst the entire mechanism revolves around a secondary centre at a slower rate. In actual process,the wear of the tool could affect the material removal function, and make the process unstable, thusin fact, it is difficult to make a deterministic manufacturing. The focus of the present paper is onwearing characteristics of sub-aperture tools and the wear evenness as the main objectives. To makea further study, material removal function of the tool is firstly established through theoreticallymodelling, next, a correlative function with weighted factors is built, which is suitable forspecifying the wearing degree of the tool. Finally, to discover the relationship between the materialremoval rate and the tool wearing characteristics, and to optimize the grinding process, analysis andexperiments are then carried out on a K9 glass specimen by means of three kinds of tool materials,i.e., polyurethane pad, aluminum plate and pitch based on the proposed technique and model. Theresults indicated that the required high efficiency and precision could be achieved by choosingproper processes
