This paper discusses machining characteristics in the milling processes of glass with the feed direction. The machined surfaces are observed to determine the maximum feed rate where brittle fracture does not occur. It is shown that the feed direction has a large influence on the machined surface. Milling in a down-cut manner leaves brittle cracks on the machined surface. When the milling tool is fed against the inclination of the milling tool, the effect of contact area on the flank face of the edge with workpiece increases to leave brittle cracks. The critical feed rates are determined in the cutting tests with changing the feed direction. Crack free surfaces are made at a high feed rate in an up-cut manner.
