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: Functionally graded Ceramic tool Thermal stresses
