Comparison of Methods to Measure Grinding Temperatures

Abstract

Experimental measurements of grinding temperatures are used to estimate the energy partition to the workpiece. In the present investigation, three different temperature measuring techniques are compared for estimating the energy partition in grinding. Grinding temperatures were measured in the workpiece subsurface under identical surface grinding conditions using an embedded thermocouple and a two color infrared detector, and on the workpiece surface using a foil/workpiece thermocouple. All three methods gave comparable temperature responses which were consistent with analytical predictions for the same energy partition.
