Optimization by Simulation of Surface Machining on Cnc Machine Tools Using Cad-cam Techniques

The paper is focused on the theoretical and practical application aspects concerning the approach methods to CNC simulation using the CATIA program, Machining module. The authors propose some variants of optimization, such as: the type of the cutting tool used, path and division pattern of the stock left for machining, parameters of cutting regimes, efficient use of machine-tools (rotative speed, feed and positioning speed) and tools (durability), reducing the processing time in order to obtain the imposed precision (roughness) etc. There are presented some images and numerical data obtained from simulations, which permit conclusions about the possibilities of optimizing the machining process.
