METHOD TO DETERMINE A QUALITY ACCEPTANCE CRITERION USING FORCE SIGNATURES

摘要

The use of force signature measured at the first and second sets of elements is provided a method for determining the quality Mechanism for reference. The first set does not have any quality defects, the second set has a deliberately quality defects. Initial selection of a subset of the time points is based on a statistical analysis of the power data of the power in the two sets of signatures. Receiving quality criterion comprises a quality threshold Mahal la formed using nobiseu distance (MD) values, the MD value is generated from the power data in the selected subset of the initial time point for each of the elements in the two sets. The output of the receiving quality is determined based on the separation of a group of elements having a quality defect such as a group of elements that quality defects and deliberately have any quality defects of the elements having a power signature. ;
