PCBN Tool Wear for Hard Materials Based on Thermodynamics Principals [PDF]
The Open Mechanical Engineering Journal, 2015 The temperature rise exceeds over 1000°C in cutting process while working with PCBN tools high speed machining. This intense temperature results in wearing of tools and thus diffusion and oxidation are mainly responsible for wearing. This paper proposes the oxidation and diffusion wearing for PCBN cutting tools and analysis has been carried out ...

Effect of welding speed on friction stir welds of GL E36 shipbuilding steel
Journal of Materials Research and Technology, 2019 The aim of this study was to characterize mechanical and microstructural characteristics of friction-stir-welded GL E36 shipbuilding steel. The tool rotational speed was kept constant at 500 rpm and different welding speeds were used (1, 2 and 3 mm/s) to
