Abstract

A variety of factors have been shown to influence each measurement process, including environmental elements, the characteristics of the measured object, and the capabilities of the measuring instrument. These factors can be categorised into several overarching groups: external factors, the measurement object, the measuring instrument, and the operator. The present paper sets out a methodology for the evaluation of part quality in the domain of optical manufacturing. The methodology under discussion employs a measurement system analysis (MSA) method. Typically, MSA is applied to two or three operators; however, in this study, it is performed for four operators. In the course of the experiments, ten optical workpieces, lenses, are measured, with each lens undergoing three measurements. Each of the four operators measured the same set of lenses, employing the same measuring instrument. The measurement of identical parts and apparatus serves to eliminate the influence of the measuring instrument on the measuring system and to evaluate the influence of the operator. The objective of this work is to demonstrate the feasibility of employing MSA as a method for assessing the quality of more than three operators. To this end, four distinct analyses are implemented to assess the influence of each operator in relation to the others.
