1. Moldagem por injeção de microcomponentes ópticos poliméricos gerados em insertos usinados por torneamento de ultraprecisão / Injection molding of polymer micro-optical components generated in inserts by ultra-precision turning
Este trabalho analisou o processo de moldagem por injeção de micro elementos ópticos difrativos usinados em insertos de cobre eletrolítico com ferramenta de diamante com ponta única. Quatro tipos de microestruturas características foram selecionados neste estudo, a saber: lente anesférica, lente de Fresnel, grade de difração (blaze grating) e sensor

2. Single point diamond turning of the tungsten carbide / Usinabilidade do carbeto de tungstênio no torneamento com ferramenta de diamante
The single point diamond turning of the Tungsten Carbide is presented. The motivation for this study is the material´s high hardness and potential application for micromolds. A Tungsten Carbide sample was subjected to tests for determination of cutting parameters to achieve the ductile regime of material removal. Based on experimental results it was conclud

3. Avaliação da replicagem de moldes torneados com ferramenta de diamante usando prensagem a quente em polimetilmetacrilato (PMMA) / Evaluation of the replication of molds generated from single point diamond turning using hot embossing in polymethylmethacrylate (PMMA)
In this work, different types of microstructures were generated by single point diamond turning and microindentation for will replicated through the hot embossing. Tests were carried to evaluate the generation these microstructures by two distinct methods: micro-deformation and micro-machining, planned to observe the replication of the mark generated by the

4. Micromachinability study of Ti (CP) and Ti-6Al-4V alloy by means of single point diamond turning / Estudo da microusinabilidade do Ti (CP) e da liga Ti-6Al-4V no torneamento com ferramenta de diamante
Among the various applications where titanium and its alloys are employed, the aeronautic industry is one of the most important, because of their excellent properties such as fracture strength, corrosion resistance and high strength to weight ratio, which is maintained at high temperatures. However, the machinability of titanium and its alloys is generally c
