Use of statistical tolerances

Statistical tolerances are gaining an increasing application in industrial manufacturing. In certain branches of industry, such as automotive industry, the use of statistical tolerances is required. The use of statistical tolerance reduces production costs. This paper will comment the assumptions that are made regarding the values of process capability index upon which the calculation of statistical tolerances is based. Certain clarifications are demonstrated on an example of calculation of statistical tolerances. The example contains both arithmetic and statistical analysis of tolerances and analyses of worst case scenario cases which can appear during manufacturing of assembly parts.
