Abstract

RUBIO, Juan C. Campos et al. Furação com alta velocidade de corte em compósitos poliméricos reforçados com fibras de vidro. C.Tecn. Mat. [online]. 2007, vol.19, n.3-4, pp.83-87. ISSN 0870-8312.

High speed machining is an outstanding technology which allows increasing competitiveness with regard to both the quality of the machined component and machining costs. This work is concerned with high speed drilling of fiber reinforced polymeric composites. In spite of the advantages offered by this category of materials generally associated to their specific strength, fiber reinforced composites are considered difficult to machine materials owing to the accelerated tool wear rates  resulting from abrasion, in addition to the fact that the fibers anisotropy affects chip formation. Therefore, the knowledge related to the machinability of metallic alloys cannot be directly applied to polymeric composite.
