A PHENOMENON LEADING TO AN ERROR IN MEASURING THE CUTTING TEMPERATURE BY TOOL WORK THERMOCOUPLE METHOD*

Abstract

The paper deals with an error experienced in measuring the cutting temperature by the tool work thermocouple method. The problems when using a high speed steel tool and carbon steel for metal cutting are described. The experimental results suggest that when using high speed steel as part of the thermocouple, error appears in the temperature range when carbide dislocation occurs.
