Gauge repeatability and reproducibility study is still relevant today in many industries and the manufacturing sector. It is becoming most important as the requirements of manufacturing tolerances are becoming more stringent. Variability in measurement systems has come under heavy scrutiny as requirement for tolerances becomes tighter. This paper focuses on the variability of a manual measurement system in determining the gauge capability. The paper is also a further study of a previous paper titled: “Design of Experiment for Gauge Capability and Comparison of Variability for Discrete and Scanning Methods of Obtaining Data”. Venier caliper is the manual measurement system used in this paper for the capability study. The experiment designed in the previous paper mentioned above was adapted to the manual system and put to use here. Results were obtained, analyzed, discussed and conclusions were deduced thus: though automatic measurement systems might be more expensive and very in outputs, they have smaller variability.
