Dynamic effects on cutting forces with highly positive versus highly negative cutting edge geometries

Investigation of Cutting Forces Superalloy Inconel 718

Since the cutting tools used in machining process of super alloys are subjected to high cutting forces, accordingly tools life is reduced, therefore improvement in alloys machining and reducing cutting forces to achieve longer tools life is an essential necessity. In this research, the effect of changes in feed rate on cutting forces in machining process of nickel based super alloys is investig...

Experimental Study of the Effect of Laser-Cutting Process Parameters on Heat Distribution and Cutting Edge Quality of Steel Sheets

This study aimed to evaluate Laser-cutting process of Mild Steel St37 sheets with two different thicknesses. In order to evaluate the quality of cutting edge and the depth of the area affected by the heat, several tests were conducted to determine the effect of parameters such as Laser power, Laser beam movement speed and pressure of axillary gas on the quality of cutting edge and the depth of ...

Graft-versus-Host Disease T Cells Play a Dominant Role in Cutting Edge: Highly Alloreactive Dual TCR

The Cutting Edge

“The bigger they are, the harder they fall” is a bit of wisdom that’s been around for a long time. But when it comes to pesticide application, the line should read, “The bigger they are, the closer they fall.” Large droplets are not as likely to drift off-target as smaller droplets. This basic principle lies behind many innovations to reduce drift when spraying herbicides. Nozzle manufacturers ...

Cutting-edge terahertz technology

Terahertz (THz) radiation, which lies in the frequency gap between the infrared and microwaves, typically referred to as the frequencies from 100 GHz to 30 THz, has long been studied in fields such as astronomy and analytical science. However, recent technological innovation in photonics and nanotechnology is now enabling THz research to be applied in many more sectors. Today, THz technology is...
