THERMAL STRESSES ANALYSIS OF FUNCTIONALLY GRADED CERAMIC TOOL

Abstract

Abstract: The thermal stresses in functionally graded ceramic tool are calculated using finite element methods. Results show that there is little difference between the thermal stresses in the functionally graded ceramic tool and in the common ceramic tool in lower cutting speed. While the thermal stresses in the functionally graded ceramic tool are much smaller than in the common ceramic tool in high cutting speed conditions. This phenomenon show that functionally graded ceramic tool is more suitable for high-speed cutting.

Key words: Ceramic tool, Functionally graded, Thermal stresses, Force modeling, Machining mechanism, Micromilling
