Method and device for checking the compliance of a workpiece

A device for checking a compliance of a workpiece having at least one characteristic, comprising a measuring machine configured to measure a value of said at least one characteristic, a command module, transmission means configured to transmit measured values from the measuring machine to the command module, and to transmit instructions from the command module to the measuring machine, the command module being configured to estimate a risk of non-compliance of characteristic on a basis of a law of probability associated with characteristic, to verify whether the estimated risk of non-compliance satisfies a decision criterion, wherein the decision criterion comprise a first criterion whereby it is verified that the estimated risk of non-compliance is lower than a fixed threshold, and, if so, to declare that the workpiece is compliant for the characteristic;

• if not, the command module being configured to instruct the measuring machine to measure a value of the characteristic to determine whether or not the workpiece is compliant on the basis of the value thus measured, and to update the law of probability associated with characteristic on the basis of the value thus measured,
• wherein the decision criterion comprises a second criterion whereby it is verified that a value, that is a function of the estimated risk of non-compliance and of the estimated risks of non-compliance of workpieces for which the decision criterion has previously been applied, is lower than a threshold which is a function of a number of said workpieces.
