ResumoThe natural tool-chip contact length is affected by a large number of parameters in the cutting system, one of which is the tool material. Wide variation of the contact length is observed in machining of steel with tools of different grades, distributed over the whole range of sintered carbides, all other variables being kept constant. Experiments show that there is good correlation between contact length and the thermal conductivity of the tool material. Based on the results of the experiments, the conclusion is drawn that contact length and chip curl are predominantly governed by the variation of the temperature field in the tool-chip contact zone.
