The present paper deals with the contact mechanism between the coated abrasive belt and the workpiece. The contract length, the pressure distribution on the contact zone and the normel force applied to a cutting edge are analyzed experimentally. The contact stress distribution on the broad interface between an elastic cylinder and a rigid plane is analyzed by the conventional photoelastic stress technique under combinations of normal-and tangential-loads at the interface. The pressure distribution on the interface agrees with that on the contact zone between the belt and the workpiece obtained by the force measurement in simulated process by a single grain. The pressure distribution along the contact length is in parabolic and is caused by the elastic deformation of the contact wheel. The normal force applied to the individual cutting edge and the locus of th, abrasive grain penetrating into the workpiece during grinding are also discussed.
