Imitating modeling according to the method of Monte Carlo is offered. In lines of a spreadsheet process of manufacturing and the control of a metric thread of a bolt is modeled. In columns are modeled: the serial number of a product, the true amount of the average diameter of a thread, the estimation of the conformance of a product on a two-point scale, the various valid error of measurement at use of the chosen gauge, the total result of manufacturing and measurement, i.e. the valid amount of the average diameter of a thread, the percent of conformance details. By the concrete example dependence of the risk of the manufacturer on size of the extended indefinite form of type B measuring instrument is shown. The technique is intended for training of masters (technologists and metrologists), and also for researches.
Keywords: the average diameter of a thread, an indefinite form, an error, a deviation, the percent of incorrectly discarded goods
