tungsten carbide -cobalt WC-Co is a composite material which is very hard and difficult to machine among the conventional machining methods pendulum surface grinding has successfully been used for removing thin layers of this material this paper deals with sheel wear and workpiece surface roughness in creep-feed grinding of tungsten carbide with20% cobalt binder using a resin-bond diamond whieel experiments show that the wheel wear radial & side corner increase and surface roughness decrease with increase of feed rate on the other hand wheel wear and surface roughness decrease with increase of wheel speed.
