Abstract: A planet diamond abrasivetool can achieve the purpose of widening grinding area, improving the use efficiency of abrasives and reducing the cost, which doesn’t need any dressing techniques and tools. It could solve some problems of diamond abrasivetool, such as inefficiency of abrasive use, deficiency of cooling, repetitiousness of dressing and so on. This paper describes the characteristics of the planet-abrasivetool and presents an equation for grinding a curving face by the new tool on five-axis grinding machine. At last, the developmental potential of the planet-abrasivetool is predicted.

Abstract: A novel precision grinding technique optimum is proposed for grinding workpiece’s convex surface. The grinding point moves in radial direction on wheel’s planar face, while the grinding wheel feed in forward and backward direction. The calculation model of cutting location is established, experiments and data are shown. The advantages are illustrated by achieved higher precision grinding, extended life span of wheel, reduced deformation of machining system, and easier dressed following dullness. Via comparing the machining error to conventional methods, it is suggested that technique is an optimum option, in particular, for grinding convex surface of workpiece made of brittle and hard materials.
