| Abstract: | A comprehensive investigation is made on the dynamic aad static machinability of metal. The influence of heat-treatment on the machinability of the commonly-used steel, the No. 45 steel, is studied both theoretically and experimentally. A microanalysis is made of chips to find out the mechanism of how a metal is cut. It is shown that the dynamic and static machinability of metal is essentially different qualitatively and quantitatively. The conclusion arrived at is that proper heat-treatment can improve the machinability of a material. |
