A brief review of numerical simulation in process machining

Machining is a technological process that involves removing the material by generating chips, aiming to obtain flat, cylindrical, helical surfaces etc. This processing method is widespread in the industry and it is, therefore, necessary to define appropriate technical and economic solutions concerning the materials and geometry of the tools, the orientation and fixture of the devices, and the machine-tool used. It is also particularly important to use the most appropriate cutting parameters for modern industrial applications. Scientific research addresses these issues through analytical, semi-empirical, or numerical modeling. Numerical modeling and simulations can satisfy with very good precision the solutions of these aspects, with diverse methods and techniques used in the study of the cutting simulation. This paper presents an analysis of recent studies, briefly presenting the main approaches and techniques used in numerical modeling and simulation of machining. The input parameters, components, and output parameters of these numerical models are identified as well. Finally, the advantages and disadvantages of using these methods and techniques are summarized, as well as the problems to be developed in the area of numerical modeling and simulation of cutting processes.
