Description

Promovidoporum consórciocompostopelaPALBIT,S.A.(promotorlíder),pelasUniversidadesde Aveiro e de Coimbra, o projeto 3D_CompCer visa o desenvolvimento de ferramentas de maquinação complexasatravésdetécnicasinovadorasdemanufaturaaditiva,nomeadamentefresas,com sistemasderefrigeraçãointerna,alargando ocampo deaplicaçãodestasfresas emcondiçõesmais agressivas, com tempos de vida útil superior.Odesenvolvimentodenovasferramentasdiferenciadasdasexistentesapresentacomoinovaçãoa possibilidade de alargar o campo de aplicação das ferramentas de maquinagem de base cerâmica em condiçõesmaisexigentesdemaquinaçãoecomtemposdevidaútilsuperiores.Paralelamente,a otimização da geometria das ferramentas, através da introdução de canais internos de refrigeração, permitirá reduzir significativamente o peso das ferramentas e simultaneamente diminuir o consumo de matérias-primas de custoelevado, nomeadamente ocobalto, carboneto de tungsténioe carbonitreto de titânio. Finalmente, o processamento por FA é o mais adequado para protótipos, uma vez que não requer o investimento em ferramentas de prensagem, normalmente necessárias para o processamento pulverometalúrgico convencional, i.e. prensagem uniaxial e sinterização.Em suma, a otimização do processamento por FA em materiais de base cerâmica para aplicação em ferramentasdemaquinaçãotrazbenefíciosaoníveldodesempenhodasferramentas,reduçãode material e celeridade no processamento.O projeto 3D_CompCer, com duração de 33 meses, tem previsto o desenvolvimento de 6 atividades principais que contemplam tarefas associadas ao processamento aditivo de compósitos de metal duro e cermetos; ao processamento 3D cerâmicos nitreto de silício; à produção de protótipos; à realização de ensaios de desempenho; divulgação de resultados e gestão do projeto.
