摘要:Nowadays, there are urgent demands of micro structure/parts which have high strength in high temperature environment in the fields such as aerospace, energy, power, bio-medical, etc. Nickel-based superalloy Inconel 718 is the suitable material for manufacturing the kind of micro parts. Micro-milling can be applied to manufacture Inconel 718 micro components. Different processing conditions lead to different residual stress on workpiece surface, which has a significant effect on reliability and working life of product. To study the residual stress problem in micro-milling of Inconel 718, the investigation of micro-milling Inconel 718 process was implemented based on ABAQUS simulation. The model based on the input of cutting parameters and the output of surface residual stress was developed. At last, the experiments of micro-milling Inconel 718 were conducted to verify the validity of model. The work offers reference for selecting cutting parameters in micro-milling of Inconel 718.
