Jan 01, 2014 Grinding temperature prediction The thermal effects due to the grinding process have a significant effect on the produced residual stress. Previous work by [3, 4] have shown that elevated temperature result in tensile stress on the workpiece surface. Jaeger [7] proposed a method of determining the temperature rise based on moving heat source.

There is yet another way of expressing the second law of thermodynamics. This version relates to a concept called entropy.By examining it, we shall see that the directions associated with the second law—heat transfer from hot to cold, for example—are related to the tendency in nature for systems to become disordered and for less energy to be available for use as work.

Thermodynamics in physics is a branch that deals with heat, work and temperature, and their relation to energy, radiation and physical properties of matter. To be specific, it explains how thermal energy is converted to or from other forms of energy and how matter is affected by this process. Thermal energy is the energy that comes from heat.

Interaction of process and machine in grinding of hard and brittle materials such as cemented carbide may cause dynamic instability of the machining process resulting in machining errors and a decrease in productivity. Commonly, the process and machine tools were dealt with separately, which does not take into consideration the mutual interaction between the two subsystems and thus cannot ...

May 17, 2010 In the dissertation, the grinding process is regarded as an integration of all microscopic interactions, and a methodology is established for the physics based modeling. To determine the engagement condition for all micro-modes quantitatively, a virtual grinding wheel model is developed based on wheel fabrication procedure analysis and a ...

Feb 01, 2006 “Finish with peel grinding is in the 0.24-0.4 R a range, and because of the cutting speed this process can be quite a bit faster than conventional grinding,” says Hitchiner. The physics of peel grinding also brings advantages. “You concentrate all the grinding force in one small area with peel grinding,” says Hitchiner.

Jun 04, 1998 A new mechanical grinding (MG) process in NH3 and subsequent nitriding in N2 without a crystallization treatment was developed for synthesizing Sm2Fe17Nx powders. This process features a shorter MG time compared to conventional MG to prevent amorpharization of the alloy structure and to avoid hydrogen in the ground powders which promotes a diffusion of nitrogen atoms into their particles.
