Cutting performance of grooved rake face cut-off tool.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1990 The applications of a new cut off tool equipped with a grooved rake face are discussed in relation to the cutting performance compared with that of the conventional (flat-rake-face) cut off tool. The experimental results indicate the followings :1) cutting surface roughness and chip disposal are improved and cutting forces are decreased ;2) cutting ...

Nano-Cutting Fluid for Enhancement of Metal Cutting Performance [PDF]
Materials and Manufacturing Processes, 2012 Nano-cutting fluids are the mixtures of conventional cutting fluid and nanoparticles. Addition of the nanoparticles can alter wettability, lubricating properties, and convective heat transfer coefficient (cooling properties) of nano-cutting fluids. In the present work, nano-cutting fluid is made by adding 1% Al2O3 nanoparticles to conventional cutting ...

Cutting performance of a cemented carbide drill with three cutting edges.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1991 In this paper, an investigation of the cutting performance of a cemented carbide drill with three cutting edges is reported. Drilling tests were performed in which the eccentricity, straightness, cylindricity, and roundness of machined holes were measured using the least squares technique. Surface roughness was also measured.
