Abstract - This paper presents a summary of numbers of
researches done by the different authors on the dressing and grinding operations. Dressing is a conditioning process of grinding wheel to increase its efficiency and to make it more productive. Grinding is an abrasive machining process used for almost every manufacturing process to improve the surface finish with the help of abrasive grits. This paper reviews the various process parameters like dressing orientation, feed rate, depth of cut and number of passes and their effect on the surface roughness, grinding wheel performance and wear. And the recent development and progress in the field of dressing and grinding is reviewed from the different perspective.
Dressing operation is performed to restore the shape of a grinding wheel. It is a finishing process of wheel to minimize the grinding forces and increase the grinding efficiency. Different types of electroplated, vitrified and metal bonded dressers are used for dressing operation. Also, optimization of some dressing parameters such as dressing orientation, depth of cut, number of passes and speed give the better results of grinding.
Key Words: Grinding, Dressing, process parameters, surface roughness
1. INTRODUCTION Nowadays a wide range of grinding and dressing techniques are used for machining the variety of engineering materials. These processes include internal, cylindrical, centerless and surface grinding. Also, single point dressing and internal arc dressing are the types of dressing process. These methods are widely used in order to increase productivity and quality with better surface finish. Grinding is an abrasive machining process of material removal used to shape and finish the different components made up of metals and non-metals. Since 2000 years, abrasives are used for shaping the material. In early times, resharpening of weapons, knives and tools were done by abrasive stones. Grinding as a manufacturing process was developed in 1959. Now, it is used for high technology applications such as aero engines and missile guidance system.
