End Milling. End milling is probably the most common class of operations performed on milling machines. End mills are cylindrical cutters that normally have two or more cutting edges on both the periphery and end of the tool. End milling operations include side milling, slotting, facing, or partial facing, pocketing, profiling, and contouring.
1 The Grinding Wheel 1. Introduction The grinding wheel is a multi-tooth cutter made up of many hard particles known as ''abrasives'' which have been crushed to leave sharp edges which do the cutting. The abrasive grains are mixed with a suitable binding material called bond, which acts as a matrix or holder when the wheel is in use. Figure 1 shows an exaggerated image displaying …
