• Research on Development of On-Machine 3D Measuring System of Grinding Wheel Surface Topography by Stereo Images

抄録

The shape and distribution of abrasive grains in the grinding wheel have a significant influence on the grinding performance. Therefore in order to realize the high-precision grinding process, it is essential to measure the shape and distribution of abrasives on wheel working surface. We have developed an on-machine 3D measurement system to study the surface topography of grinding wheel by binocular stereopsis without demounting the wheel from the grinding machine. In comparison to the results measured by the laser microscope, the developed system has been confirmed to have the accuracy of -5.6% in the horizontal direction and -3.4% in the vertical direction. Also, we analyzed the behavior and variation of individual grains by tracking observation of 3D topography of the grinding wheel working surface in the grinding process by using this system. As the result, the distribution and variation of abrasive grains including protrusion height, flat part length, half-tip angle, grain density and effective cutting edge density are able to be quantitatively evaluated.
