CONTROL OF VARIABILITY FOR MAN MEASUREMENT

Anne-Sophie Guerra, Maurice Pillet, Jean-Luc Maire

Abstract

In a visual control, the measurement system is human. Each appraiser must control the part and judge the conformity. Consequently, the subjectivity of measure is very present and the variability therefore high.
The subjectivity of this inspection is generated by two aspects: the exploration i.e. the capacity to perceive the defect by the appraiser and the evaluation i.e. the capacity to evaluate correctly the defect. So, after to realize the exploration and after to have made the evaluation, the appraiser could with more of facilities to give a reponse and so a judgement on the acceptability of the defect. The inspection must be separated into two operations: the exploration and the evaluation.
