Ecodesign of the Aluminum Bronze Cutting Process

Abstract

The realization of products from materials with high properties generally involves very high energy consumption. Thus, in the research, it was considered to optimize the machining process by cutting of an aluminum bronze alloy, so as to obtain a reduction in energy consumption in correlation with the roughness of the machined surfaces. The research focused on the processing of a semi-finished product with a diameter of Ø = 20 mm made of aluminum bronze (C62300). In addition, in the research, the aim was to establish some correlations between the amount of power consumed and the quality of the surfaces processed by cutting. In this sense, the forces were measured in the 3 directions specific to the cutting process (Fc; Ff; Fp) for 3 tools construction variants and power consumed. The results showed that, if a certain constructive variant of the cutting tool is used in the processing, a reduction of the power consumed to cutting can be obtained by approximately 30% and a reduction of the roughness of the processed surface by approximately 90–100%. Furthermore, following the statistical processing of the results, it was shown that it would be advisable to use, especially in roughing processes, the cutting tool variant that offers the greatest reduction in roughness and cutting power.

Eco-Design of Polymer Matrix Composite Parts: A Review

“…Such an approach is not considered incorrect, but based on the industry's understanding of eco-design, we can demonstrate that this definition is incomplete. A significant argument arises from analyzing the multiple definitions of eco-design under its various names and concepts, observing that numerous recurring terms are encompassed within this field in various scientific works, such as [5,12,17,18,21,24]. These recurring terms can be classified into four main categories: This classification allows for a deeper understanding of the relevant domains and priorities within the eco-design of composite materials with a polymer matrix.…”

“…Considering this imbalance caused by the depletion of certain raw material sources and the growth of industrial activities in polluting countries, as well as the challenges in recycling large quantities of composite materials with a polymer matrix, sustainable alternatives must be urgently found. These alternatives should address ecological, economic, and social aspects [17]. In this regard, it is imperative to conduct an analysis to identify the most important factors that contribute to greenhouse gas emissions or pollutants, factors that increase energy consumption, factors that affect the health and safety of operators or the areas they live in, and economic factors that increase production costs.…”
