Skruvar standard Enligt ritning. A good set of engineering tolerances in a specification , by itself, does not imply that compliance with those tolerances will be achieved. Actual production of any product or operation of any system involves some inherent variation of input and output. Measurement error and statistical uncertainty are also present in all measurements.

With a normal distribution , the tails of measured values may extend well beyond plus and minus three standard deviations from the process average. Appreciable portions of one or both tails might extend beyond the specified tolerance. The process capability of systems, materials, and products needs to be compatible with the specified engineering tolerances.

Process controls must be in place and an effective Quality management system , such as Total Quality Management , needs to keep actual production within the desired tolerances. A process capability index is used to indicate the relationship between tolerances and actual measured production. The choice of tolerances is also affected by the intended statistical sampling plan and its characteristics such as the Acceptable Quality Level.

An alternative view of tolerances[ edit ] Genichi Taguchi and others have suggested that traditional two-sided tolerancing is analogous to "goal posts" in a football game : It implies that all data within those tolerances are equally acceptable.

The alternative is that the best product has a measurement which is precisely on target. The previous edition of ISO published in had the envelope criterion as the default association I am having trouble figuring out how to get the tolerance tables to work.
