The experimental research strategy of the end- milled aluminum alloys Alina Bianca Pop 1 , and Mihail Aurel Țîțu 2,* 1 SC TechnoCAD SA, Vasile Alecsandri no. 72, code 430351, Baia Mare, România 2 Lucian Blaga University of Sibiu, Victoriei Street no. 10, code 550024, Sibiu, România Abstract. In this paper, the most important aspects of the research methodology of the resulted surface quality by aluminum alloys end- milling, are presented. The first part of the paper includes a short presentation of the cutting processes aluminum alloys evolution. In the second part, the research problem was defined by setting a fundamental objective and identifying the specific objectives which contribute to achieve the fundamental objective. In this context an experimental study, was performed, starting with the organization and conducting the end- milling process, in which the cutting regime were established, then the characteristic measured parameters were determined, so that the research factors and parameters will result. 1 Introduction Each science has its own history that marks its development stages. Paul H. Black’s book "Theory of Metal Cutting" has a starting point the paragraph "Metal Cutting - Art to Science" in which assumes that cutting history began with 600000-1000000 years ago, somewhere in Tanganyika, Africa. The cutting processes development started since the 19 th century [1], when the first experimental tests were conducted aimed to explain the chip formation [2]. Later, in the 1930s, the sintered metal or mineral-ceramic materials were discovered, than in 1950 the indexable cutting inserts were carried which were widespread in the production, leading to the new tools types development. The machining process has a considerable age with a continuous evolution derived by the progresses occurred in the new materials developing, also by the cutting tools and machine tools improvement. The machining process is closely related to the costs, it is desired to raise the machine tools and machining centers performance, and also the new products continuous development, which also contributes to increase the machined parts precision. Choi [3] presents a fairly detailed theory accompanied by a number of applications related to surface modeling techniques used by different software for computer aided design/computer-aided machining. Following a literature review, conducted on the materials used in the cutting processes [4], it was found that over the last decade, the researches have focused particularly on steels. This statement is supported by the Table 1 [5], in which the percentage comparison of the workpiece materials use frequency is presents. * Corresponding author: mihail.titu@ulbsibiu.ro DOI: 10.1051/ , 01010 (2017) 71120101 112 MATEC Web of Conferences matecconf/201 IManE&E 2017 0 © The Authors, published by EDP Sciences.
