Abstract:

An extensive investigation is made on the influence of flank rubbing on tool-work and toolchip interface temperatures for the machining of a quenched and tempered alloy steel. Local flank temperatures are measured by a photoconductive, infra-red radiation detector. Temperature distribution and rate of energy dissipation at both interfaces are computed therefrom using a geometric electric analog. The foregoing results, together with tool force dynamometer data, makes it possible to examine changes in frictional behavior at both interfaces as wear develops. It is concluded that the wide difference in the rigidity of the toolwork and tool-chip pair plays an important role in the wear mechanism. Author
