The cutting edge of the chisel should be sharpened to an acute angle so as to provide for the best cutting ability, depending on the stock to be chipped. The work of the wedge depends mainly on its cutting angle.
Under the effect of an external force applied to the wedge it cuts into the metal. A chisel is a tool made of very hard steel, having a cutting edge at one end of the blade. There are different tools used in metal-working shops for chipping stocks such as chisels. The workpiece to be tooled is fixed during the cutting process in the bench vice. Chipping of large parts is always done on an anvil but very often it is done in a bench vice. Chipping is used in cases when it is necessary to cut off a piece of metal from sheet metal. This process is used when a large piece of metal has to be removed from a workpiece this process is very labour-consuming 1 and is applied only in cases when the workpiece cannot be machined. Chipping is a process of removing metal from a workpiece by means of a cutting instrument such as a chisel and a hammer.
