On some fundamental problems in grinding L.C. Zhang,«i ? g^6 H. Noguchi^ T. Waida^ *Dept. of Mechanical Engineering, Sydney University, NSW 2006, Australia *> Machining Tech. Div., MEL, 1-2 Namiki, Tsukuba, Ibaraki 305, Japan ABSTRACT This paper studies some fundamental problems in grinding towards high surface integrity. Discussions are addressed on the modelling of wheel modulus, interface forces, contact length and the surface heat source simulation.
