Item Analysis of the Effects of Tool Wear on Dry Helical Milling of Ti6Al4V Alloy(2015) Fernández-Vidal, S. R.; Mayuet, P.; Rivero, A.; Salguero, J.; Del Sola, I.; Marcos, M.; SGIt is not easy to find papers that contain studies about the holes development in Ti alloys by alternative machining processes such as helical milling. The increased competitiveness and legislative requirements in the aeronautical sector has caused the necessity to develop products and processes seeking the greatest profitability and sustainability, taking as reference the so-called four axes for manufacturing performance: economy, energy, environment and functionality. This work reports on the first results of a study about the influence of cutting speed and feedrate on the hole finishing in the oriented helical dry milling process of alloy Ti-6Al-4 V.Item Tool-path effect on the geometric deviations in the machining of UNS A92024 aeronautic skins(2017) Del Sol, I.; Rivero, A.; Salguero, J.; Fernández-Vidal, S.R.; Marcos, M.; SGTraditionally, aeronautics skins are being machined by chemical milling, a high-pollutant process. An efficient alternative to this technology is conventional machining. However, to ensure the parts machined with this process keeps the industrial quality controls, the effect of tool-path might be characterized, specially analyzing final thickness and roughness. In this paper, five different tool-paths have been applied under the same machining parameters in the dry milling of Al-Cu UNS A92024 thin plates. Machining time, final thickness and roughness have been evaluated. Most roughness and thickness results are under the industrial quality limits stablished for this type of parts.
