“…As operações de corte de metal são generalizadas na indústria de transformação e a previsão e / ou o controle de parâmetros de usinabilidade sempre atraem interesse. Um parâmetro básico de usinabilidade é a textura da superfície, pois está intimamente associada à qualidade, confiabilidade e desempenho funcional dos componentes [12].…”

Através de ensaios preliminares a este estudo, um inserto de corte de modelo DNMG 150604 RK4315 foi definido para realização dos ensaios. As variáveis de entrada determinadas foram a velocidade de corte (V c ) e o avanço de corte (f n ), sendo fixado o valor da profundidade de corte (a p ), para todos os ensaios. Com o objetivo de determinar a vida útil do inserto nas 6 configurações de corte aplicadas, foi definido como desgaste de flanco máximo do inserto o valor de 0,3 mm conforme norma ISO 3685. Assim, pode-se comparar não somente os resultados de tempo de usinagem, mas também valores como taxa de remoção de material (Q) e rugosidade média (R a ) encontradas para cada configuração dos parâmetros de corte. Com os resultados encontrados pode-se então analisar a melhor condição de corte no torneamento externo para o material ASTM A518 GR.3 com a utilização do inserto DNMG 150604 RK4315, realizando a comparação dos melhores resultados obtidos quanto a vida útil da ferramenta, bem como rugosidade média (R a ) resultante e volume de material removido (cm 3 ). A configuração dos parâmetros de corte definida como a mais adequada neste estudo apresentou a maior vida útil, o maior volume de material removido (cm 3 ) e a terceira menor rugosidade média (R a ) perante as 6 configurações testadas. Palavras-chave: Usinagem; Torneamento; Parâmetros de corte; ASTM A518 GR.3.

“…The primary microstructural features of conventional and modern brass rods have been extensively highlighted and discussed in relation to behaviour during machining [27]. Factors such as the chip size, cutting tool type and wear, cutting force, surface roughness and testing methodology play an important role in the optimisation of cutting processes in terms of time and cost [28][29][30]. In this direction, optimisation algorithms have been applied to investigate the optimal number of passes and the corresponding parameters such as speed, feed rate and depth of cut in each pass for multi-pass and multi-criterion plain turning problems [31].…”

The recent environmental/health and safety regulations placed restrictions of use of hazardous substances on critical manufacturing sectors and consumers’ products. Brass alloys specifically face a challenging issue concerning the elimination of lead (Pb) which has been a critical element affecting both the machinability and overall quality and efficiency of their manufacturing process. The adaptation of novel materials and processing routes in the green economy constitutes a crucial decision for competitive business and industry growth as a worldwide perspective with substantial industrial and social impact. This paper aims to review the emergent innovative and sustainable material solutions in the manufacturing industry, in line with environmental regulations, by highlighting smart alloy design practices and promoting new and innovative approaches for material selection and manufacturing process optimisation. In this review we analyse the processing, structure and machinability aspects of leaded brasses and underline the major guidelines and research methodologies required to overcome this technical challenge and further improve the mechanical properties and machinability of lead-free brass alloys. Various alloying and processing strategies were reviewed together with the most important failure types, as they were extracted from the existing industrial and technological experience, covering more than 20 years of research in this field.

“…Tool life characteristics of brazed carbide cutting tool machined against mild steel and optimization of machining parameters based on Taguchi design of experiments upon three factors including spindle speed, feed rate and depth of cut were examined by Dasgupta et al [9]. Vaxevanidis et al [10] investigated the machinability characteristics of a CuZn39Pb3 Brass alloy by evaluation of the cutting force, arithmetic surface roughness Ra and maximum height of profile Rt during longitudinally turning process considering the effects of rotational speed; feed rate and depth of cut. Klocke et al [11] investigated the influence of tool coating and material on the machinability of low-leaded brass alloys (Pb<0.2%) to solve tool wear during external turning of CuZn21Si3P due to the hard silicon-rich κ-phase.…”

In order to be competitive in manufacturing industries, it is essential to create high performance machining processes in manufacturing plant. One of the effective ways to improve the performance of machining processes is cutting tools. Although there are various standard cutting tools, it is also possible to design a special tool to have high performance cutting by eliminating the number of steps. This study focuses on designing a new cutting tools to have high performance machining process of one of the commonly known brass alloys, CuZN40Pb2 in mass production. In this study, two teeth form brazed carbide boring tools with different geometries in terms of radial rake angle and cutting-edge radius have been utilized in order to evaluate the machining performance during boring operation of CuZn40Pb2. Edge radius of brazed carbide cutting tools varied to enhance performance of cutting tool and resulting cutting forces and surface quality of machined parts are examined carefully. It illustrated that this designed tool provides high performance cutting by controlling some design parameters including edge radius and rake angle.
