Experiment is conducted to verify the validation of the model. Simulated chip morphology in different cutting parameters agrees to the experimental results very well. Based on the FE model  cutting stresses  equivalent plastic strains  temperatures distribution and cutting forces are obtained and analyzed. This provides a good method to investigate the micro milling principles.

The rare earth compounds were dispersed in the SiO2 colloids and the monodisperse nano-scale composite materials were prepared. The reactant mass fraction and heat treatment temperatures could affect the structures and emission spectrum properties of as-synthesized samples. The samples emit the strong red light upon excitation under the ultraviolet. The main peaks originate from 5D0-7F2 electric dipole transition of Eu3+. With regard to the samples treated at different temperatures  the emission spectra obtained under 266 nm excitation show different shapes of spectra lines and relative intensities  indicating that the Eu3+ ions have been located in different local environments. 2011 Published by Elsevier B.V.
