Application of Finite Deformation Theory to the Development of an Orthogonal Cutting Model—Part II: Experimental Investigation and Model Validation

Abstract

In Part 1 of this paper, a continuum mechanics model of the orthogonal cutting process was developed based on finite deformation theory. In this part of the paper, constitutive equations for O1 and L6 tool steels are developed using the results from split Hopkinson pressure bar tests. Statistically designed orthogonal cutting experiments are conducted to secure process results across a range of cutting conditions. The continuum mechanics model established in Part 1 of this paper is used to simulate all the cutting tests. All the model outputs are calculated and compared with the corresponding cutting experiment results. Good agreement is observed between the model predictions and the experimental results. The continuum mechanics model is successfully used to predict the cutting force, shear angle, and temperature.
