ABSTRACT
The production of moulded surfaces in the engineering industry is progressing. One way to produce these surfaces is using CAM systems. As well as the use of a CAM system, the correct choice of milling strategy is also important. The aim of this paper was to increase the knowledge of the finishing milling strategies effect on surface quality in the production of shaped surfaces. For the experiment, a sample containing convex and concave curves produced on a 3-axis milling machine was designed. The material used for experiment was aluminum alloy and five different strategies were compared. The results of experiment included some methods for the comparison of machined surface quality. At the beginning visual comparison of the machined surface in CAM system with the real machined surface was evaluated. Other methods of the surface quality evaluation were roughness measurement and surface texture analysis. At the end the production time with respect to the selected strategies were evaluated and compared. The experiments showed that the best roughness values the strategy Constant Z was obtained and the shortest production time was achieved by the strategy linear and linear 90.
