Abstract

The Measurement System Analysis (MSA) is a significant method which is used to analyze the measurement capability of a measurement system. It’s considered the early steps in production control and one of the quality enhancement techniques. Gage Repeatability and Reproducibility (GR&R) is a process to examine the non-conforming of tools, equipment, and operators. The Gage study tell the operators if the measurement system is acceptable for its purposed use, also shows which part of the system is contributing the most variation of the measurements, so this will help the operator to improve the measurement system. The aim of the MSA is to qualify a measurement system for use by quantifying its precision, accuracy, stability and minimizing their contribution in process variation through including method such as ANOVA. This paper study ANOVA method, using MINITAB (16) to calculate Gage R&R through taken ten samples of Aluminum shafts , and three operators to measure the outer diameter of samples by using micrometer outer diameter device. The measurement results show the variance component for gage repeatability and reproducibility is acceptable, and the excessive variance was in the Part-To- part variations.
