Temperature Measurement in the Metal-Cutting Zone of a Lathe

Abstract

A method is proposed for industrial measurement of the temperature in the metal-cutting zone. The method employs the thermal-equilibrium equation to determine the amount by which the local temperature exceeds the ambient value. The concept of a heated body is introduced: the part of the workpiece that is converted to chip and is deformable in the course of cutting. A method of determining the mass of the heated body is formulated and experimentally verified.
