Calibration elements and accuracy diagnostics at the assembly of the 5axis CNC machine An article proposes a technique for diagnosing the accuracy of 5axis CNC machine based on the designation of a "norm" of positioning accuracy to assess the possibility of correcting without additional measures. It considers the algorithm of actions when the accuracy of the established correction rates is exceeded by the measured parameters.

Metrological Supply Of Tool Manufacture The article shows that in tool manufacture it may not be enough to introduce only the GOST R 51672 requirements to metrological assurance of tool tests. On the example of the production of PJSC "MIZ", it demonstrates the expediency of applying the GOST R 8.563 requirements in addition to the implemented ones.
