A NEW METHOD FOR CUTTING TOOL TEMPERATURE MEASUREMENT USING CCD INFRARED TECHNIQUE: INFLUENCE OF TOOL AND COATING

Abstract

ABSTRACT Machining presents strongly-coupled thermal, mechanical, and metallurgical phenomena, such as friction, plasticity, and wear. A knowledge of the temperature at any point in the cutting zone is consequently essential to understanding the cutting process. A method using infrared analysis with CCD (silicon) sensors, which can directly provide the entire thermal map of the surfaces in the cutting zone is presented. This method can validate numerical models and can provide information on the influence of different cutting parameters and conditions. The influence of the tool and the coating on the temperature distribution is also discussed.
