Analysis of the impact of milling strategies on the surface roughness of 6060 aluminum alloy

Over the past few decades, important progress has been made in the field of machining, which was a result of the development of CNC machine tools, cutting tools (including tool materials and coatings), control systems and information systems. IT systems for supporting work of engineers are more frequently used. They facilitate works related to structure design, developing manufacturing technologies or organisation of the production process. In the case of machining CAM programs permit the easy generation of complex tool path. Such programs support e.g. milling of complex components with one fastening – using more than three controlled axes. In connections with a many possibilities to create tool paths in CAM software, the question arises, how to choose the most favourable path due to technological effects (such as surface roughness) and tool durability [1–5].
