1. New concept of tunnel boring machine: high performance using water jet and diamond wire as rock cutting technology
Abstract Tunnel boring machines are important tools in underground infrastructure projects. Although being well established equipment, these machinesare based on designsof more than 60 years ago and are characterized by big dimensions, enormous weight and high power consumption. Commercial aspects should be noted too. The model adopted by the TBM industry re

5. Application of the Minimum Quantity Lubrication (MQL) technique in the plunge cylindrical grinding operation
Precision cylindrical grinding is used extensively in the manufacture of precision components in the metal-mechanical industry in general. Modern CNC grinding machines have improved this process with respect to the positioning and rigidity of the machine-workpiece-tool system, allowing the production of high precision parts with low dimensional tolerances. B

7. Study of Tapping Operation of Compacted Graphite Iron With Cemented Carbide Tool / Estudo do processo de rosqueamento com macho de corte de metal duro em ferro fundido vermicular
The use of compacted graphite iron - CGI is growing in the automobile industry, replacing several components that usually are manufactured in grey cast iron. However, due to its poor machinability when compared to grey cast iron, the production cost sometimes is not competitive. Several research about machinability of CGI has already been developed, mainly i

8. Influência do ângulo de posição sobre o fresamento frontal de níquel puro com insertos de metal duro
Nickel is considered as a dificult-to-cut material, due to rapidly work hardening when machined. Because it shows high strength at high temperatures it is widely used as high temperature alloys in aerospacial components and more specifically is applied in the continuous casting industry, in molds which consist of a copper sheet with pure nickel electroplated
