A Comparative Analysis of the Machined Surfaces Quality of an Aluminum Alloy According to the Cutting Speed and Cutting Depth Variations
2019
The milling operations are a topical and especially future-oriented methods. The purpose of this scientific paper is to carry out an experimental research referring to the end-milling process of the 7136 aluminum alloy. This paper is a continuation of the own research activity carried out so far, within a company with the field of activity in the aerospace industry. The main objective is a comparative analysis which was carried out on the surface quality - machined on various cutting regimes. The cutting process parameters used in the end-milling process are: the cutting speed, the feed per tooth and the cutting depth. The obtained results of the surface roughness’s were measured longitudin…
Influence of the feed per tooth variation on the surface roughness at end milling of an aluminum alloy
2019
Abstract As a part of the cutting process, a researched aspect continuously is surface quality. Based on and using the results of previous research, the present scientific paper addresses the problem of the machined surfaces roughness. The cutting process approached in this study is the end-milling one, and the workpiece material used to carry out the study is the aluminum alloy used in the aerospace industry. The adopted cutting regime imply to keep the cutting speed at a constant value while the cutting parameters: cutting depth and feed per tooth vary with different values. The experimental research carried out by the authors in a prestigious industrial company is complicated and complie…
Optimization of the Surface Roughness Equation obtained by Al7136 End-Milling
2017
The aim of this paper is to optimize the regression equation of the surface roughness obtained by 7136 aluminium alloy machined by end-milling process. The surface roughness is dependent on certain process parameters, which can vary, causing in this way variations of the surface quality. The research method used in this paper is the experiment and the Taguchi design of experiment. The experiment was performed using an experimental stand, in which every step to get the purpose, is presented. The measurements were made using a portable surface roughness tester. In the first part of the paper the influence percentage of the involved parameters in the machining process, was determined. Then, a …
Study of the cutting process parameters that influence the surface quality machined by end milling of the aluminum alloy
2019
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 pl…
