Comparison and Research of Thermocouple Measuring Temperature Curve and Theoretical Temperature Curve in Grinding

Abstract:

A Thermocoupletemperature measurement test of grinding for steel 45 was done to analyse thereason of errors between experimental temperature curve and theoreticaltemperature curve derived by triangular distribution heat source model.It wasshown that,errors of influencing factors,such as grinding heat flow,thermalconductivity,density,specific heat capacity,limited grinding energy andeffective abrasive contact radius,have certain effect on temperature measuredby thermocouple.It was found that the influence of grinding heat flow into aworkpiece is the biggest and the effective radius of abrasive contact thesmallest.It is concluded that as long as the error of each influencing factoris controlled in a certain range,thermocouple measuring temperature curve willmatch with theoretical temperature curve closely.
