Optimization of Grinding Wheel for Improving Productivity and Life

The life of a grinding wheel is a critical factor influencing the efficiency and cost-effectiveness of grinding operations. Premature wheel wear leads to increased downtime for wheel replacement and dressing, reduced machining accuracy, and higher production costs. The key aspects of optimizing grinding wheel life through a comprehensive approach that considers various process parameters, wheel characteristics, and advanced optimization techniques. The optimization process involves a detailed analysis of the grinding process, identifying the dominant factors that contribute to wheel wear. These factors include, but are not limited to, the grinding parameters (e.g., depth of cut, feed rate, wheel speed), the workpiece material properties (e.g., hardness, toughness). The grinding wheels are mostly used in fabrication industries as well as in metal foundry industries and in construction sides also. The life of grinding wheel is depending on the RPM of grinder and the material where the grinding wheels use to perform the grinding function and raw material used to manufacture a grinding wheel. From last few months out customer facing breaking issue specially in 9” DCD (Depressed Center Disc) wheels. To resolve this issue and improve the life of 9” DCD wheel a case study is conducted to find out the possible causes of wheel braking by using a Fish Bone Diagram and 5Why and 1H methodology. The outcomes of this optimization study are expected to provide practical guidelines and parameter recommendations for industrial grinding operations to significantly enhance grinding wheel life, reduce operational costs, improve machining quality, and contribute to more sustainable manufacturing practices. The findings will offer valuable insights into the complex interplay of factors affecting grinding wheel wear and pave the way for more efficient and predictable grinding processes.
