摘要
En 中文
Precision adjustment has many applications in various fields particularly in laser generation systems and precision engineering In this paper a laser forming method for the precise adjustment of a rod with a diameter of several millimeters is investigated Experiments on precision laser adjustment are carried out using a fiber-coupled passively cooled CW diode laser The effect of important parameters is investigated in detail Parametric studies are carried out to determine suitable processing windows at which a small and stable laser-adjusting angle is obtained A coupled thermomechanical model established using the finite element method is validated and applied to predict the deformation of the rod and better understand the mechanism of precision laser adjustment A simple closed-form expression for the precision laser-adjusting angle is proposed An application on precision laser adjustment is presented (C) 2010 Elsevier Inc All rights reserved
