測量系統分析(msa)公開課

 

課程背景

幫助理解測量系統的統計特性，認識測量系統對過程控制中數據收集的影響。采用在教員引導下的練習，使學員學會偏倚、穩定性、線性、重復性、再現性分析的實踐經驗，具備開展測量系統分析和改進的能力。

Help to understand the statistical characteristics of measurement systems, and to understand the impact of measurement systems on data collection in process control. The practice of teaching under the guidance of trainer enables trainee to learn the practical experience of bias, stability, linearity, repeatability, reproducibility analysis, and the ability to carry out measurement system analysis and improvement.

學員帶著零件和量具參加培訓；主要講解MSA過程中的難點，包括如何做測量系統的分析計劃、如何選擇零件、如何做到一次盲測、如何判定、如何改進；介紹MSA第三版與第二版中判定準則的差異（采用統計假設測驗）；提供了對計數類量具的測量評價方法；對于性能測試、破壞性試驗等如何研究他們的穩定性。

Trainee with parts and measuring in training; to explain the main difficulties in the process of MSA, including how to do how to plan, how to choose the parts, so that a blind test, how to judge, how to improve the measurement system analysis; the difference of criterion for MSA third edition and second edition (using statistical hypothesis test); provide evaluation of measurement of the count measuring method; for the destruction of how to study their stability test, performance test.
