The force acting on workpiece surface generated by magnetic particle brush is important factor which affects micro cutting behavior of abrasives as machining characteristics in magnetic abrasive finishing. In this report, the normal force is measured during finishing, and intensity change of the force is found when magnetic particle is used in adsorption at the end of magnetic pole. Measured normal force indicates a little decrease continuously after the drastic increase at the start of finishing motion, although the intensity of magnetic field is constant. The mechanism of normal force intensity change is described as the transmission of compressive force caused by cutting force in the center area of magnetic particle brush. The theory can explain why friction coefficient influences the force intensity change. The intensity increase suggests active cutting of abrasives supported by magnetic particles, and is regarded to make effective results in rough surface finishing.
