A Study of Cryogenic Cooling Effects on Grinding Titanium Alloy

In this paper try with use of cryogenic cooling by liquid nitrogen damage such as surface roughness¡ micro cracks¡ surface oxidation and burns¡ as well as control the grinding force in grinding titanium alloy to get their minimum. In addition to the latest statistical techniques appropriate to the nature and effect of each of the grinding parameters (cutting speed¡ work speed and depth of cut) and the interaction effect of surface roughness on the output power of vertical and tangential force put to their optimal levels has identified. This paper demonstrates the use of liquid nitrogen as a coolant has a positive effect on reducing surface roughness and grinding forces¡ the surface also reduces the damages of the work piece and the titanium alloy surface oxidation during grinding to prevent. In addition¡ each of the parameters including¡ cutting speed¡ work speed and depth of the outputs of the paper¡ to be effective¡ for example by increasing shear rate increases the surface roughness and grinding forces are reduced¡ as well as increased depth of cut increases the surface roughness and forces.
