국방 분야 자동시험장비의 Gage R&R 분석을 통한 신뢰성 확보 방안 연구

Abstract

The utilization of unverified automatic test equipment (ATE) in production results in the absence of reliability assurance, which makes it impossible to guarantee product quality. Therefore, ATE validation is imperative. With the growing importance of ATE validation in the defense sector, various validation approaches have been researched and implemented, including initial production suitability validation and equipment effectiveness validation during first mass production. For the validated ATE, periodic checks, such as calibration history and software management status, are conducted. Current validation activities primarily focus on accuracy verification and neglect precision verification, which can lead to various issues. Inconsistencies in pass or fail determination can occur because of measurement differences between ATE units or measurements. Because ATE is primarily used for mass production, even minor errors in the process can have significant ripple effects. To address these challenges, this study establishes an approach for the precision verification of ATE and applies it to the Milsatcom-II ATE as a pilot study to confirm its effectiveness. The outcomes of this research are expected to contribute to enhancing the reliability of quality data, not only in the defense sector, but also in other industries.
