Cutting wheels are subjected to certain impact tests, bending tests and so on. The manufacturer is also obliged to ensure that the grinding wheel is well balanced prior to delivery. The bursting of a grinding wheel may cause fatal or very serious injuries to anyone in the vicinity and heavy damage to plant or premises. Identification of grinding wheel wear signature by a wavelet Grinding is known as the most complicated material removal process and the method for monitoring the grinding wheel wear has its own characteristics comparing with the approaches for detecting the wear on regular cutting tools. Research efforts were made to develop the wheel wear monitoring system due to its significance in grinding process. This paper presents a novel method for The ABCs of CBN Grinding | Gear Solutions Magazine Your Successful sharpening of cutting tools depends upon the use of the correct grinding wheel, tool set-up, and method of grinding for each type of tool.
