Edge grinding by helical scan grinding method

Abstract

The helical scan grinding method in which a wheel or a workpiece is fed at an angle with the direction of wheel rotation can greatly improve the surface roughness on the workpiece without decreasing the processing efficiency compared with the case of a plunge surface grinding. In this research work, the helical scan grinding was carried out on the edge of the carbon steel workpiece by feeding table with an inclination for investigating dressing lead. The result showed that the surface roughness kept constant in the range though it became worse in the case of normal grinding when the dressing lead was varied between 126 and 500 mm/min.
