Research on the Measurement Method of Protrusion of Impregnated Diamond Bit Crown
An improved method based on the technology of laser scanning is introduced in this paper for protrusion value measurement of working element of impregnated diamond bit. The morphology of impregnated diamond bit crown with the size of 40/65 mesh is scanned and measured by the Coordinate Measuring Machine (CMM) which is built based on the principle of triangle measurement. Due to the automatic image mosaicing function of CMM, high horizontal and vertical resolution can be obtained and larger sampling area as well. The software of reverse engineering is employed to collect and analyze the data, which could be fit the protrusion track, and then the height of the protrusion could be measured in three-dimensional space. With the above method, the diamond protrusion value measured with this measurement method is consistent with the actual value.
