Abstract

The inspection and monitoring of the wear of grinding tools is essential in order to ensure the quality of the grinding tool and the finished product. Present methods rely on dismounting the grinding tool for examination of the grinding tool surface. Often, the state of the grinding tool surface is checked indirectly by evaluating the quality of the workpiece. The application of image processing which offers an effective means for in situ inspection and monitoring is described in the paper. By using multi-directional illumination and image fusion, an image with a high degree of relevant information is generated that is then segmented using the wavelet transform (MSA) and classified to distinguish grains and cavities. Results of the application of the algorithms for a high performance grinding wheel with CBN grains embedded in a resin base are presented.
