Numerical Investigation of Dual Heating in Laser Micro-Adjustment of Actuators

Abstract:

Laser micro-adjustment as application of laser forming is a contact less and easily automated technology able to cause very small changes in shape to achieve high accuracies. In this study, a method using dual heating is introduced to reduce the temperature gradient across the thickness during laser micro-adjustment of actuators. The temperature field and deformation behavior using dual heating method are analyzed using a 3D finite element model. The in-plane angles are compared between using single heating and dual heating and the numerical results show that the in-plane angle using dual heating method can be predicted by the results by single heating.
