Grinding – An abrasive machining process that uses a grinding wheel as the cutting tool, is capable of making cuts and producing very fine finishes. The process may produce sparks, or particles of hot metal that may ignite combustible materials. Hot Work - any open flame, spark or heat producing activity and is typically associated TYPES OF GRINDING WHEELS Indian Standard Coding system of grinding wheel is IS : 551-1954. It provides uniform system of coding of grinding wheels to designate their various characteristics. It gives a general indication of the hardness and grit size of any wheel as compared with another. Coding of a grinding wheel consists of six symbols as described below Grinding Operation - an overview | ScienceDirect Topics The direction of cutting (linear preferal velocity of the grinding wheel) is always normal to the tool path, as can be seen in Fig. 3.2. It should also be normal to the direction of the fibers in the outer layer, in order to minimize the amount of energy generated due to grinding, and accordingly produce a ground surface with low surface roughness.

Metal is removed from the workpiece by the mechanical action of irregularly shaped abrasive grains in all grinding operations. This article discusses three primary components of grinding wheels, namely, abrasive (the cutting tool), bond (the tool holder), and porosity or air for chip clearance and/or the introduction of coolant. CHAPTER 1- INTRODUCTION TO GRINDING CUTTING ACTION IN GRINDING WHEEL. Since the last two decades, there has been an increased interest in the investigation of grinding processes. Grinding is the most common form of abrasive machining. It is a material cutting process which engages an abrasive tool whose cutting elements are grains of abrasive material known as grit.

During cutting, as the tip of the cutting tool strikes the workpiece, the edges of the cut become deformed due to the compressive and shearing forces. These deformations are seen as entrance burrs which are formed at the entry point of the cutting tool. Roll-over Burr: These are chips that are bent rather than sheared from the cutter‘s path.
