Research on surface integrity in milling Inconel718 superalloy

Research on surface integrity in milling Inconel718 superalloy Inconel718 has a wide application in aviation and space industry due to its superb comprehensive performance, and surface integrity is directly responsible for evaluating the quality of the components. In this paper, a series of experiments in milling Inconel718 superalloy with small diameter tools were conducted under the sustainable minimum quality lubricant (MQL) condition and the effects of milling parameters, tool installation, and cooling condition on the surface quality, work hardening degree, and microstructure alternation, respectively, were investigated in deep. Then, the variation trend of surface roughness, cutting force, and vibration based on the Fast Fourier Transform (FFT) and tool wear volume with the increased milling length was researched, which showed three different stages during the tool wear process clearly. Experiments results showed that thermal-mechanical interaction, vibration, tool stiffness, and residual area are the main reasons for the surface integrity. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png The International Journal of Advanced Manufacturing Technology Springer Journals

Abstract

Inconel718 has a wide application in aviation and space industry due to its superb comprehensive performance, and surface integrity is directly responsible for evaluating the quality of the components. In this paper, a series of experiments in milling Inconel718 superalloy with small diameter tools were conducted under the sustainable minimum quality lubricant (MQL) condition and the effects of milling parameters, tool installation, and cooling condition on the surface quality, work hardening degree, and microstructure alternation, respectively, were investigated in deep. Then, the variation trend of surface roughness, cutting force, and vibration based on the Fast Fourier Transform (FFT) and tool wear volume with the increased milling length was researched, which showed three different stages during the tool wear process clearly. Experiments results showed that thermal-mechanical interaction, vibration, tool stiffness, and residual area are the main reasons for the surface integrity.
