The paper intends to implement the use of theoretical models and computer aided simulation based on FEM for improving the teaching of cutting metals theory for the students of Machine Manufacturing Technologies and Machine Tools. The advantage of simulation, especially animated is to transpose the normal classroom into a virtual model where the skills can be evaluated under similar realistic conditions. It helps the students to be able to face the complexity of the real complex processes inside the production environment. A review of the most important models in cutting processes shows that the majority of the researches in this field tend to replace the traditional methods of calculating the cutting data parameters based on mathematical models with new complex models. The paper tries to relieve the importance of using the FEM models and simulation software for a better understanding of the process and also for providing more accurate and more detailed information. In the case studied in this paper a series of experimental models were performed for a validation of the theoretical models created by comparing the results. The advantages of using 2D and 3D animated models in the teaching and training process are also mentioned in the paper.
