Manual Measurements Of Cutting Tools On A Coordinate Measuring Machine

Coordinate measuring machines make it possible to measure the geometric parameters of precision parts, the measuring of which is not feasible with a universal hand tool.The purpose of the study was to develop a methodology for measuring the design and geometric parameters of a straight bull-nose turning tool. To test the effectiveness of the developed methodology for measuring the design and geometric parameters of the cutting tool, a full-scale experiment was conducted. During the experiment, the measurement of all the structural and geometric parameters of the cutting was carried out using hand-held measuring tools and the Wenzel XOrbit 55 coordinate measuring machine. A comparative analysis of the results of the measurements showed the folowing: all the geometric parameters of the cutting can only be measured using a coordinate measuring machine; geometric parameters measurements using a universal hand tool do not allow you to make unambiguous organizational decisions on the further operation of the cutting tool, since the measurement error is comparable to the current size tolerances, however, for such design parameters as length, height, and width of the cutting, due to the large tolerances, it is sufficient to use a universal hand measuring tool. The measurement practice using a coordinate measuring machine has shown that when performing critical measurements, the use of coordinate measuring machines, in manual mode, is not only accurate, but also more productive in comparison with a universal hand measuring tools.
