Machining

INTRODUCTION 1.1 ELECTRICAL DISCHARGE MACHINING (EDM) The phenomenon of erosion of metals by electric spark was first noticed by Joseph Priestily in 1878 but this was not used for machining of metals until 1930s. Controlled machining of metals by electric sparks was first done by Lazarenko in Russia in 1944 [2]. One of the most widely used Non-Conventional Machining process in industry is Electrical Discharge Machining (EDM). Electric Discharge Machining is a non- traditional concept which is

Abstract Milling is a vital process used in the industry to make and assembling the components. The extensive and expensive experimental work is necessary to determine the optimal of machining process parameters for obtaining the desired machined quality. In this regard, the present work is focused on the relationship between the input process parameters and machined surface integrity for minimizing the machined damage. Moreover, the paper presents the comparative analysis and performance of two

unstable self-excited vibrations known as regenerative chatter can occur, causing excessive tool wear or failure and a poor surface finish on the machined work piece. There are several analyzing techniques that are used to increase the stability of the machining process such as, fuzzy arithmetic techniques, stability lobe diagram(SLD),Structural dynamic modification. Based on these analyzing techniques how the operating variables are changed to obtain the different predicted results is studied. Keywords:

Zeal for technical advancement in the field of science and technology always fascinated and motivated me to opt for engineering. To meet the best possible grades in my career, I expect to continue my knowledge hunt in an esteemed university which enhances the growth of my interest. The challenges of developing new and better materials to meet demanding needs, keeps a material science engineer at the cutting edge of technology. Mechanical engineering by itself has many subjects in the course module

CHAPTER 1 INTRODUCTION 1.1 PROJECT BACKGROUNG Technologies involved in machining operations have advanced greatly in the recent decades and machines have experienced significant changes such as the incorporation of numerical control. Every year it is possible to observe in fairs, conferences and of course in the market economy, how production capabilities have increased thanks to the development of new concepts, devices, materials, tools, coatings, structures, etc. Accuracy, flexibility and

surface roughness, surface damage and machining forces all varies severely with fiber orientation. Introduction: Glass fiber reinforced plastics (GFRP) have been widely used in aircraft, automobile and structural applications. The components need high quality machined surface, better dimensional accuracy and surface consistency. But machining mechanism of composite materials is not easy to understand, because of its inhomogeneous and anisotropic behavior. The machining leads to several damages such as

Introduction CNC Vertical End Milling Machining is a widely accepted material removal process used to manufacture components with complicated shapes and profiles. During the End milling process, the material is removed by the end mill cutter. The quality of the surface plays a very important role in the performance of milling as a good-quality

importance to derive many advantages such as manufacturing process flexibility, high strength to weight ratio. The machining of composites is always not preferred because of the structural disturbances generally occur due to damages caused by machining forces to the fiber matrix interfaces, which in turn leads to the reduction in the mechanical properties of composite as a whole. However machining is necessary in special situations where the dimensional tolerances are to be maintained very close in the

composites on machined surface quality used by diamond abrasive cutters. Here the cutting forces, surface roughness, specific cutting energy and work specimen temperature were evaluated and analyzed. Lastly, all of these factors are also influenced on machining responses [22]. Qin et al. focused on full factorial experimental design for milling of CFRP composites and all helical milling experiments were carried out with a customized cutter.
