THE BURN INTENSITY OF THE GROUND SURFACE EXPRESSED BY SURFACE LIGHTNESS INTERVAL

The burn or surface oxidation of ground surface is one of the first indicators of incorrect grinding process. Burning can be smaller or greater, so it is possible to talk about the burn intensity of the ground surface. In this paper the burn intensity has been determined and presented by means of the surface lightness interval, which has lower and upper value, and measurements were carried out on the Image Analysis System LECO2001. The lower value of the surface lightness interval describes the darker colour of ground workpiece or analysed image, and the upper value is the lighter colour. The lower value of the surface lightness interval SVd , is more relevant for determination of the burn intensity, since it describes greater burned ground surface of the workpiece. The paper represents some results of investigation of dependence of lower value of the surface lightness interval on dressing and grinding conditions.
