Machinability has been studied by engineers for over 75 years, beginning with the significant contributions of F. W. Taylor between 1881 and 1906. 1 Since then, the mechanics of metal cutting has been extensively studied, and considerable progress has been made in developing theories of machinability based on a knowledge of mechanical ... garland 4th of julyFree machining steels are carbon steels that have sulfur, lead, bismuth, selenium, tellurium, or phosphorus added. Sulfur forms the compound manganese sulfide, which is soft and acts as a chip-breaking discontinuity. It also acts as a dry lubricant to prevent a built up edge on the cutting tool. Lead works in a similar way to sulfur. Bismuth achieves a free machining steel by melting into a thin film of liquid for a fraction of a microsecond to lubricate the cut.
