Control of the axisymmetric temperature distribution in a circular saw has been shown to be an effective means of reducing blade vibrations. Theoretical and supporting experimental analyses of a basic induction heating coil design are presented here. An IR thermometer was designed to measure the blade temperature. Transient heating, transient cooling and steady state temperature experiments on circular saws were conducted both in the laboratory and in production. The true set point temperature was maintained to within 2 C.
