Abstract: One precise method used in the industry for several years to think about measurement instrument repeatability and reliability across quite a lot of inspection agents is the Gauge Reproducibility & Repeatability (GR&R) tool. GRR Studies have become critical in process improvement projects in the manufacturing sectors. There are various methods to conduct GRR study. However, the most widely used is the Automotive Industry Action Group (AIAG) method, which was standardized after the recognition of the importance of measurement systems. In this study, AIAG method, variance component method, ANOVA method and Control chart method are compared for Twist per Inch (TPI), a quality characteristic of the yarn processes. Usually, the GR&R study wants to be conducted earlier to the process capability analysis for verifying the exactness of measuring equipments and helping organizations develop their product and service quality. Therefore, how to make sure the quality of measurement becomes a vital task for quality practitioners. In textile spinning industry, the quality measurement includes usually, Neps, Strength, Elongation, Evenness, Twist variation, Hairiness etc. Whereas the present study deals with the evaluation of accuracy of the yarn strength for the TPI data that leads to reliable decision concerning yarn quality. The measurement system analysis (MSA) is then used to observe the reliability of the data due to operators. Due to this, the yarn strength measurement system is inappropriate and need improvement regarding operators. Hopefully, the results of this study can supply a useful reference for quality practitioners in various industries.

Key words: ANOVA; Gauge R& R; Measurement system analysis; Spinning industry; Yarn strength.
