Summary

In this diploma thesis we study the process of constructing a complex geometry product using programmable machines (CNC) with milling process in five axes. Emphasis is placed on products such as radial impellers compressor which require a considerable time for machine tool programming and final product processing. Initially, specialized 3D modeling software (CAD) is used to design the product and then process software (CAM) to create / customize the different machining required. Simulation of the different processing conditions (propulsion, turns and cutting depth) is performed on each surface, with the aim of improving the final processing time. At the same time, the processing programs (CNC code) are extracted so that the simulation values are compared with real processing conditions in a 5-axis CNC milling machine of the Inter-Machine Workshop Laboratory, for the presentation and comparison of the simulation results and experimental data. Finally, roughness measurements are performed on different cutting treatments, aiming at studying the effect of the cutting conditions used to treat the impeller.
