A novel sound-based grinding belt condition monitoring method using OP-ELM model has been developed and validated with experimental data. The following conclusions can be made. (1) There are three kinds of belt wear styles in superalloy grinding: abrasive fracture, rubbing wear and debris adhesion.
Grinding burn causes an irreversible change in the microstructure of a surface layer . Therefore, controlling and monitoring grinding burn is of great interest to all industries that depend on this process, because it reduces scrap workpieces and production costs. Another very important aspect of the grinding process is workpiece surface quality.
where b and r are the disk width and radius, respectively, F N is the normal force applied at the end opposite the disk, and a is the gradient of the regression line obtained from the characteristic displacement curve versus (t) 2/3, or the characteristic curve of sharpness of the grinding wheel, where t is the experiment time or contact time.. Works involving monitoring …

The grinding operation gives workpieces their final finish, minimizing surface roughness through the interaction between the abrasive grains of a tool (grinding wheel) and the workpiece. However, excessive grinding wheel wear due to friction renders the tool unsuitable for further use, thus requiring the dressing operation to remove and/or sharpen the cutting edges …
A virtual verification system for grinding wheel condition monitoring by use of a neural network and fuzzy logic was developed by blending vibration, AE and grinding forces sensor outputs . AE and force signals have been used for classifying the tool conditions into four distinct classes namely sharp tool, used tool, chip noise, and tool ...

The vibration signal is a useful new tool for monitoring the advanced ceramics grinding process. 2 Literature review 2.1 Monitoring advanced ceramics in grinding process. Indirect monitoring by sensors is highlighted among the tools used for empirical modelling.
Wear is an inevitable problem in abrasive belt grinding, and the material removal rate decreases with continuous wear of the abrasive belt. This indicates that the grinding control force is affected by two dynamic factors, namely the actual material removal and abrasive belt wear state. To obtain an accurate force-control model to achieve uniform material removal, a …
