Abstract
Traditionally, the development and optimization of the machining process with regards to the sub-surface deformation is done through experimental method which is often expensive and time consuming. This paper presents the development of a finite element model based on an updated Lagrangian formulation. The numerical model is able to predict the depth of sub-surface deformation induced in the high speed machining of Inconel 718 by use of a whisker-reinforced ceramic tool. The effect that the different cutting parameters and tool micro-geometries have on sub-surface deformation, will be investigated both numerically and experimentally. This research paper also address the temperature distribution in the workpiece and the connection it could... (More)
Traditionally, the development and optimization of the machining process with regards to the sub-surface deformation is done through experimental method which is often expensive and time consuming. This paper presents the development of a finite element model based on an updated Lagrangian formulation. The numerical model is able to predict the depth of sub-surface deformation induced in the high speed machining of Inconel 718 by use of a whisker-reinforced ceramic tool. The effect that the different cutting parameters and tool micro-geometries have on sub-surface deformation, will be investigated both numerically and experimentally. This research paper also address the temperature distribution in the workpiece and the connection it could have on the wear of the cutting tool. The correlation of the numerical and experimental investigation for the sub-surface deformation has been measured by the use of the coefficient of determination, R2. This confirms that the finite element model developed here is able to simulate this type of machining process with sufficient accuracy. (Less)
