Derivation of Equations and the Heat Distribution Graphs in Vibration Assisted Machining and Comparison with the Conventional Machining

Article Preview

Abstract:

The numerical analysis of the cutting zone average temperature and the temperature distribution of the chip and cutting tool are performed in this paper. To derivate the equations, the conditions of both conventional and horizontal vibration assisted machining are analyzed and the results are compared. The previous finite element results along with the experimental results show good agreement with the numerical results achieved from this research and explain the temperature reduction in the cutting zone. The results clearly show that horizontal vibration assisted machining excels the heat distribution in the tool and chip, which justifies the tool wear reduction in this process.
