Validation of Fe Modeling of Orthogonal Turning Process Using Cowper–Symonds Material Behavior Law

Gyliene V., Ostasevicius V.

Engineering Transactions

2013

Vol. 61, iss. 4

249–-263

The article contains a literature review, experimental results, and a Finite Element Model (FEM) composition. Orthogonal turning tests were executed in the range of cutting speeds and feed rate, after every test chip was collected. Further investigation was done using FE model validation and experimentation, which uses results of the experimental zone in which the built-up edge did not form and the cutting itself is of even plastic deformation. The essence of this research is that the adequacy of the composed FE model to the real physical process should conform not only to the evaluation of cutting forces, but also to the evaluation of chip form, that is, segmentation frequency.
