摘要

本研究主要在探討規矩塊比測儀之量測系統的能力分析，其目的在提升校正儀器設備的品質的要求，以確保在進行校正時的品質系統穩固。儀器設備在量測時所產生的總變異量涵蓋：量測環境的變化、量測設備的精度、量測人員的訓練、經驗與受測工件的規格，這些變異來源所產生的變異量需加以數據化及圖表化，才能明顯表示量測系統的量測能力。
量測系統分析主要分析的項目為：穩定性、偏倚、線性、重複性與再現性5種品質特性。依照不同的品質特性設計出不同實驗模式，在實驗數據完成後應用統計手法：假設檢定、單一樣本t檢定、兩組樣本t檢定以及線性迴歸分析、變異數分析法（F檢定）做評估；再使用MINITAB統計軟體執行各項性度分析，並列出分析圖表。

最後判定儀器的量測能力表現是否合格，可提供儀器校正人員及品保工作者做參考，此分析法有助於查核儀器在品質系統內的異常與否，應用此分析法判定量測系統，也更能明確地表示對品質系統的保證。

The study is to discuss the measurement system capacity analysis of Gauge Block Comparator. The purpose is improving the quality requirement of calibration instruments to ensure the stability of quality system while calibrating. The total variance arisen from measuring instruments includes: the variety of measuring environment, the precision of measuring equipment, the experience of measuring staff and the specifications of the workpiece under test. The variance arisen from these sources of variation must be made into data and chart to show the measuring capability of measurement system.

The main items in measurement system analysis are: stability, bias, linearity, repeatability and reproducibility. Different experimental models are designed according to different characteristics. After running the data, we can estimate these data with some statistical methods which include: hypothesis test, one-sample t test, two-sample t-test, linear regression analysis, analysis of variance (F test). Then we use statistical software (MINITAB) to do the reliability analysis and to list the analysis charts.

Finally, we determine if the measuring capability of instrument is qualified to provide a reference for instrument calibration personnel and quality assurance workers. This analysis method helps us check if instruments are abnormal in quality system. Using the analysis method to determine the measurement system can more clearly show the assurance in quality system.
