Abstract
This research aims to carry out an elaborate experiment by witch resulting in relevant conclusions that have practical applicability in the aeronautical industry. The surface roughness measured transversely and longitudinally on the feed motion direction of the cutting tool constitutes the dedicated objective function on which the study was conducted in this case. The end milling was chosen of an aluminum alloy used explicitly in the aeronautical industry. The actual experiments were carried out in the only aeronautical industry in Romania carrying out these types of machining and were made according to the methodology with rigorous experimental planning of the research. The experimental plan conceived after which the practical experiments were conducted led to applied research already put into practice within the above-mentioned industrial organization.
Highlights
A important aspect of the cutting operations is the workpiece that has to be accurate, both in terms of surface quality and dimensional precision
Among the representative studies carried out in this direction are the research carried out by Warhade, which analysed the optimal combination of feed rate, cutting speed and cutting depth, of aluminium machining in order to obtain the shortest processing time, with the lower CNC power consumed and the rate of removal of the material as high as possible [1]
After the carried out experiments according to the established experimental plan, the surface roughness measurements were obtained and based on these, a series of graphs were made https://doi.org/10.10 51/matecconf /201929 0 02010 which centralizes these values and in which it can be followed the influence of each set cutting parameter exerted on the surface quality
Summary
A important aspect of the cutting operations is the workpiece that has to be accurate, both in terms of surface quality and dimensional precision. These conditions must be achieved as soon as possible and at the lowest possible energy consumption. The quality study of the machined surface, depending on the process parameters of the aluminium alloys, is subject to a significant number of scientific papers, among which are mentioned: Gökkaya [3], Kuttolamadom [4], Doddapattar & Lakshmana [5], Köklü [6], Patel [7], Singh [8], Vakondios [9], Durakbaşa [10], Gulhane [11], Kannan [12], Patel [13], Tammineni & Yedula [14]
