“…They also described and discussed aspects of the ISO standard (ISO 1997) and stressed the specificity of including a sensitive analysis for this latter. Young et al (1997) proposed a chronological study of the industrial response to environmental preoccupations, and more recently, Guinée et al (2011) provided an article dealing with a detailed history of LCA methodology and its probable evolution in the years to come, totally in line with the previous work. This article describes how LCA, which was basically a tool for evaluating environmental impact, was integrated and promoted by governments all around the world as the core element of their environmental policy.…”

“…This can be explained by a clear lack of international communication concerning the methodology employed. The evolution between 1970 and 1990 as a reactive period moving to a compliant period explains the discrepancy in methodology by the fact that it takes time to become aware of environmental aspects (Young et al 1997). …”

“…The first industries to come under scrutiny were the chemical processes and heavy industry sector, however this has tended to evolve to cover other sectors and different sizes of industry. The response of industry to mounting environmental pressure was progressive (Figure 1): it began with a "reactive period" (1970s) and crossed a "compliant period" (1970s-80s) before reaching a "proactive period" (1990s) with a real industrial response to environmental issues (Young et al 1997). The most recent period is an "integrated and progressive period".…”

“…A detailed treatment of the application of LCA to process selection, design and optimization was published (Azapagic 1999), and since this early review, methodological aspects of LCA have been improved and the methodology is more and more accepted within the scientific community. The starting point for the use of LCA for sustainable development has been the design of "environmentally friendly" products, and this approach was progressively extended to the process industry (Young et al 1997). Basically, the methodology was mainly applied to products, by developing the "from cradle-to-grave" approach to the life cycle (as described in the previous section), targeting just the product because the process, from this point of view, is considered as a part of the product life cycle (manufacturing the product).…”

Cerâmicas avançadas no processo de retificação cilíndrica externa de mergulho utilizando a técnica da mínima quantidade de lubrificação (MQL) com rebolos diamantados

RESUMONas últimas duas décadas, as cerâmicas avançadas têm sido exaustivamente utilizadas em aplicações na indústria devido às suas propriedades de elevada resistência ao desgaste e dureza. Entretanto, ainda se tem um alto custo agregado ao acabamento da peça. Esse acabamento geralmente é feito pelo processo de retificação, único processo economicamente viável que produz superfícies de elevada qualidade e precisão geométrica. Nesse contexto, as empresas vêm buscando a otimização no processo de retificação como, por exemplo, a redução do fluxo de fluido de corte utilizado, o que também visa atender exigências mundiais de preservação ambiental. Desta forma, este projeto pretendeu explorar a técnica da Mínima Quantidade de Lubrificação (MQL) na retificação cilíndrica externa de mergulho em cerâmicas com rebolos diamantados. Foram utilizados dois métodos de refrigeração: o convencional e o MQL, com três avanços de corte para cada caso. Foram usados um bocal convencional e um bocal para o MQL, tendo este um uniformizador de saída do jato. Foram analisadas como variáveis de saída: a emissão acústica, relação G, aspecto da superfície via microscopia eletrônica de varredura (MEV), rugosidade e circularidade.Assim, embora a refrigeração convencional ainda apresente os melhores resultados em comparação com a refrigeração com MQL, esta última pode atender os requisitos necessários para diversas aplicações, em especial quando utilizadas baixas espessuras equivalentes de corte (h eq ). Além disso, a técnica de MQL possui a vantagem de gerar um menor impacto ambiental em comparação com a lubrificação convencional, devido ao uso mínimo de fluido de corte cujo descarte é cada vez mais regulamentado e custoso. Palavras -chaves: Cerâmicas avançadas, rebolos diamantados, retificação cilíndrica externa, MQL.Advanced ceramics in the external cylindrical plunge grinding using the technique of minimum quantity of lubrication (MQL) with diamond wheels. ABSTRACTAdvanced ceramics have been extensively used in applications in industry in the last two decades because of their properties of high resistance to wear and hardness. Nevertheless, the finishing process highly increases the cost of pieces and components. The finishing process is, in most cases, grinding, the only viable process that produces high quality surfaces and guarantees geometric precision. In this context, companies are seeking to optimize the grinding process by, for example, reducing the usage and flow of cutting fluid, which also helps to achieve global environmental preservation requirements. Thus this project sought to exploit the technique of Minimum Quantity of Lubrication of the external cylindrical grinding in ceramics with diamond wheels. The project used two methods of cooling, the conventional and MQL, with three feed velocity in each case. We used a conventional nozzle, a mouthpiece for the MQL the latter having a uniform output of the jet. Variables were analyzed as the output acoustic emission, G relationship, surface condition by scanning electron microsco...
