Description: The dependence of the risk of manufacturer is certain on the extended uncertainty of measuring mean. An imitation statistical design is used. In lines of a spreadsheet process of manufacturing and the control of a gear wheel is modeled. In columns are modeled: the serial number, the true amount, the estimation of the conformance on a two-point scale, the varies valid error of measurements at use of the chosen gauge, the total result of manufacturing and measurement, the percent of conformance details. Methods are intended for teaching of master’s degrees (technologists and metrologists), and also for researches.
Keywords: gear wheel, the thickness of a tooth, uncertainty, an error, a deviation, the percent of incorrectly discarded teeths
