Abstract
The main objective of this work is to present a numerical and experimental procedure to estimate the parameters for the orthogonal cutting process. The mathematical model of the problem is based on the concepts of limit analysis, frictional unilateral contact, Finite Elements Method and techniques of mathematical programming. From the other hand, experimental procedures are carried out by considering different cutting parameters. The calibration of the model is assessing by comparing the numerical and experimental results. The proposed strategy is effective in the estimation of flow configuration, cutting forces and friction stress in the interface between the tool and the chip.Additionally, it would be possible to study the sensitivity of the process with respect to cutting parameters and the wear in tools. In order to reduce the wear in tools and improve the quality of the final product, the target is to propose a methodology able to control the machining process just in time and adjust the work conditions on time.
