Abstract

Highlights: Experimental set-up to measure rake face temperature during dry orthogonal cutting is described. A new technique to calibrate infrared camera to be used with gray bodies is proposed. This technique allows obtaining temperature values without the need of emissivity correction. New temperatures achieved in the rake face when machining AISI 4140 are given. The effect that oxidation and depositions have in IR rake face images is discussed. Abstract: A new method for measuring temperature in the rake face of a tool during dry orthogonal cutting using thermography is presented. In addition, a new technique is also used to calibrate the infrared camera. Using this technique, real temperature values from camera response are directly obtained without the need for emissivity correction. Emissivity is thus not an uncertainty source. These techniques were applied to machining AISI 4140. Rake face temperatures are reported and correlation with cutting forces outlined. The set-up effectively showed temperature distribution on the rake face.
