Four grinding state signals need to be removed to ensure complete contact between the diamond grinding wheel and the workpiece surface. The four grinding stage signals removed include the force signals of the first two grinding stages and the last two grinding stages, as shown in Fig. 3(c). Noise signals often appear in the grinding process.

Grinding removes material using fixed abrasive particles that produce chips of the specimen material (see below). The process of making chips with a sharp abrasive grain produces the lowest amount of deformation in the specimen, while providing the highest removal rate.

The success of the manufacturing process which involves grinding as one of the stages depends solely on the accuracy of the grinding process. Being the last stage of the manufacturing path, it is mostly done to provide the desired surface finish to the product. This makes the stage very crucial. To prevent the ruining of all the previous stages and efforts, the real-time monitoring of the ...

The topography of the grinding wheel is important in an analysis of the grinding process. By measuring the number and worn area of the active cutting edges, Suto and Sata [1] developed empirical models to simulate grinding behaviour. The results of the simulations showed good agree- ment with experimental results.
