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.
