Full textO jato d\'água abrasivo (AWJ) é uma técnica versátil que tem sido efetivamente aplicada ao corte de rochas desde o fim da década de 1980. A complexidade da interação entre o jato e as rochas dificulta a compreensão detalhada dos fenômenos envolvidos no corte de rochas com AWJ. Por um lado, rochas são materiais complexos gerados em ambientes sem interferência humana. Por outro lado, o AWJ age com alta velocidade e turbulência, dificultando a observação direta do procedimento. Assim, a presente tese de doutorado visa a contribuir com o estudo do corte de rochas com AWJ, incluindo análises de dados qualitativos e quantitativos, ambos de grande importância em estudos de materiais complexos. A análise quantitativa possui foco na investigação da eficiência de corte, a qual pode ser analisada por meio da observação das condições em que há a maior taxa de corte associada à mínima energia fornecida pelo AWJ por volume de rocha removido. Além disso, a eficiência real do corte pode ser analisada a partir da investigação das condições em que a maior parte da energia fornecida pelo AWJ é usada para efetivamente cortar a rocha, descontando perdas por dissipação. Os efeitos da variação da velocidade transversal de corte e da pressão da bomba nos parâmetros de corte também foram investigados, além da influência das propriedades das rochas na energia efetiva de corte. A energia efetiva de corte, denominada energia relativa de formação da ranhura (EKR), foi calculada com base na energia específica e no trabalho de destruição específico dos materiais. Análises de microscopia eletrônica de varredura (SEM) e petrografia foram conduzidas para visualizar e compreender melhor os diferentes efeitos do corte nas rochas estudadas. Os testes de corte realizados com velocidade transversal do bocal de 200 mm/min e pressão da bomba de 400 MPa apresentaram as melhores eficiências de corte considerando-se ambos os métodos de análise de eficiência. Dentre as propriedades das rochas investigadas, a massa específica e a resistência à tração por compressão diametral apresentaram correlações razoáveis com EKR, enquanto que o modulus ratio apresentou as melhores correlações. Observou-se que a ruptibilidade possui papel fundamental na compreensão dos fenômenos envolvidos no corte de rochas com AWJ.

This thesis guides the reader through the design of an inexpensive XY stage for abrasive water jet cutting machine starting with a set of functional requirements and ending with a product. Abrasive water jet cutting allows for mass customization of 2D parts, such as inlaid tiles. Most water jet cutters are based on a prismatic-prismatic design (gantry type). In an effort to reduce the number of precision parts in the machine, a rotary-rotary parallel drive design is proposed. The proposed mechanism will be actuated by electric DC windshield wiper motors directly coupled to the links, this eliminates the need for gearing mechanisms that add up to the total cost and complexity of the design. Kinematics of the design is simulated for a working area of 310mm x 310mm. Dynamic analysis is performed and the concepts of decoupled and configuration invariant inertia are derived, simplified to a set of conditions on the kinematic structure/mass properties of the arm linkages and applied to significantly simplify the mechanism's control system. The XY stage was designed to be inexpensive and small enough to be placed in hardware stores, garages and small machine shops. A vision of water jet cutters sold in boxes stacked on shelves in Wal-Mart, available for all machinists, artists, schools, and industries might one day thus become a reality if the pumps could also be made cheaply.

Full textDesign as an activity for developing material goods, has been adding cultural characteristics and local knowledge in the development of products. The interest in cultural products brings progress for the producing regions, reflecting in different areas of social life, promoting and increasing the competitiveness of the local market. For this reason technologies are very important, to promote innovations in products, to enable the production process and new applications. So, the union of these two factors, technologies and valorization of cultural products, providing products with a bigger added value, may result in improvement for the producing region and also for its Country. Serpentinite, a rock used as a rare ornamental gemstone occurs in Rio Grande do Sul State (Brazil) and currently does not have commercial use. The main mineral of this rocks are of serpentine group, that may occur as massive and lamelar aggregates (antigorite and lizardite) and as fibrous crystals (chrysotile). This research aims to study processing techniques to apply in this serpentinite, in order to increase its use as gemological material for use in jewelry. The mineralogical characterization of serpentinite were done with a stereoscopic loupe, X-ray diffraction and with petrographic microscopy. The processing techniques tested were cut by water jet, laser engraving, polishing and resin coating. To analyze the interactions of this techniques with the serpentinite, it was used a stereoscopic loupe, a Scanning Electron Microscope (SEM) and a gloss meter. The results obtained with the application of the processing techniques in serpentinite are good, but vary according to the texture of the rock. In rocks with predominance of antigorite and lizardite, is recommend the use of cutting by water jet and the use of filled shapes laser engraving to obtain surface textures. In rocks with chrysotile, it is recommended to use precision cut diamond saw and the use of laser engraving lines and fill shapes to create graphics of medium complexity. To obtain a good polishment, the use of silicon carbide (carborundum) sandpaper is recommended, with the grit of 180 until 2000, for rocks with predominance of antigorite, and the grit of 320 until 2000, for rocks with predominance of chrysotile. The sanding time for each step is 2 minutes with a speed around 300 rpm. To protect the material and to obtain a better luster, is recommend the application of an acrylic resin as a final step of the improvemente process.
