Description: In the article the analysis of accuracy of manufacturing of the main components of nozzles, jigs, fixtures and auxiliary equipment in production conditions. Deduced analytical dependences for calculation of error coordinated sizes taking into account the position deviation axis machined holes in parts. The main groups of factors and established their influence on the accuracy of processing coordinated sizes. The influence of error mutual orientation of elements of the equipment (spindles with tools and devices with the work piece) for precision machining coordinated holes.
Keywords: accuracy, deviations, coordinated hole, the size, the error the tool
