Grinding is one of the most important finishing operations and useful too. The loss of abrasives from the grinding wheel is undesired but unavoidable. Selection of the optimum parameters for grinding must incorporate effective utilization of i) the available energy ii) the strength and hardenss of the abrasive grits. To meet this end, an investigation has been initated in the present work to develop a model and formulate a mathematical expression involving the depth of cut, cutting speed, feed rate and strength of the material of the grit. Assuming the shape and dustribution of the abrasive grits from rational intuition along with some simplicity, a force and stress analysis of the grits has been made to derive an equation involving the three grinding parameters. For a given wheel specification, an optimum value of one cutting parameter can be determined from this equation, by fixing the other two parameters each at a given value.Keywords

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.Keywords
