  • Metal cutting puts extreme demands on the tool and tool material through conditions of high forces, high contact pressures, high temperatures, and intense chemical attack by difficult to cut work materials. In addition, the tool geometry and cutting conditions in terms of sharp edges, cyclic engagement and presence of cutting fluid will add to the severity. Most often cutting tools are used close to their ultimate resistance against these loads, especially to the limiting thermal and mechanical stresses. ...

  • Today, greater emphasis is being placed on a component’s ‘machinability’ , but this term is an ambiguous one, having a variety of different meanings, depending upon the production engineer’s requirements. In fact, the machinability expression does not have an authoritative definition, despite the fact that it has been used for decades. In 1938, Ernst in his book on the ‘Physics of Metal Cutting’ , defined machinability in the following manner: ‘As a complex physical property of a metal...

  • The two basic cutting tool types used in the metal working industry are of the single point and multi-point design, although they may differ in appearance and in their methods of application. Fundamentally, they are similar in that the action of metal cutting is the same regardless of the type of operation. By grouping a number of single point tools in a circular holder, the
