1. An Investigation on Surface Roughness and Tool Wear in Turning Operation of Inconel 718
ABSTRACT: This paper investigates the influences of three different input parameters, such as feed rate, insert nose radius, and insert coating methods, in the turning operation of Inconel 718. The coating methods were selected as medium temperature chemical vapor deposition (MT-CVD) and physical vapor deposition (PVD) and in addition to coating methods, the

2. 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.

3. Estudos de processos térmicos decorrentes da usinagem: aplicação de problemas inversos em furação / Thermal studies of cutting process. Inverse problem application in drilling
Heat generation is a common problem during any type of cutting, but particularly during a drilling due to the difficulty of conducting heat away from the cutting edge and the fact that the chips remain in contact with the tool for a relatively long time in a hole. Cutting temperatures have strongly influenced both the tool life and the metallurgical state of

7. 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

8. Resistencia mecanica e microestrutura de duas ligas odontologicas fundidas a base de cobalto
Cobalt alloys are utilizcd in various applications, includingaeroplane turbines, cutting tools, cardiac valvcs and prosthesis. These alloys have been used in dentistry for more than half a century in prosthesis, because of their excellent charactheristics in terms of biocompatibility, strength, oxidation resistance, dcnsity, and castability. But, the fail in
