Laser beam machining (LBM) process deals with material removal with high precision using localized heating characteristics of lasers. Polymers used in different electrical, electronic and Micro-electromechanical systems need to be machined to get desired shape. Machining of these polymers is difficult using conventional machining process. With its large range of process parameters and precise localized heating, LBM provides solution to machining problems of polymers. In the present research, CAD is used to design gear profiles which can be used in electronic systems. These gears are cut from Acrylic film using LBM. The influence of different input parameters namely laser Power, weld Speed and Frequency of laser on profile geometry are studied. Response Surface Methodology (RSM) is used, with the responses chosen as Addendum Diameter (ADD) and Dedendum Diameter (DD). Results are further analyzed and correlations are made using ANOVA approach.

Abstract


Laser beam machining (LBM) process deals with material removal with high precision using localized heating characteristics of lasers. Polymers used in different electrical, electronic and Micro-electromechanical systems need to be machined to get desired shape. Machining of these polymers is difficult using conventional machining process. With its large range of process parameters and precise localized heating, LBM provides solution to machining problems of polymers. In the present research, CAD is used to design gear profiles which can be used in electronic systems. These gears are cut from Acrylic film using LBM. The influence of different input parameters namely laser Power, weld Speed and Frequency of laser on profile geometry are studied. Response Surface Methodology (RSM) is used, with the responses chosen as Addendum Diameter (ADD) and Dedendum Diameter (DD). Results are further analyzed and correlations are made using ANOVA approach.
