MEASURING QUALIFICATION OF THE PROGRAMMABLE POWER DEVICE BY GAGE R&R ANALYSIS

Summary/Abstract: Aim: Today, the main purpose of quality improvement studies is to reduce the variability and realize the production of faulty products at the lowest level. Sufficiency of the measurement system should be examined before the studies to increase the quality are conducted. Because when an inappropriate product is produced in the production process, although there is no problem with the adequacy of the process, if the measurement system is not capable of measuring it or there are variations due to measurement errors, the quality improvement studies to be performed may be inconclusive. In order not to waste the efforts made to increase the quality, it is necessary to analyze the adequacy of the measurement system first. This study aims to analyze the measurement capability of the programmable power supply device.Method: The variability in the measuring system has two components: repeatability and reproducibility. Repeatability refers to variability arising from the measuring instrument, while reproducibility refers to variability arising from operator and operator-part interaction. The analysis of these variations is expressed as Gage R&R analysis. Analysis of variance (ANOVA) method is generally used for this analysis. In this study, ANOVA method was used for Gage R&R analysis of the measurement capability of the power supply device.Findings: In this study, the adequacy of the programmable power supply device in the security laboratory of a company operating in the white goods sector for tea machine power measurement according to EN 60335-1 standard was analyzed by Gage R&R method. In the study, 3 operators measured the power of 10 tea machines 2 times at different times.Result: The results obtained from the analysis show that 1.34% of the total variability is caused by the variability of the measurement system and 98.66% is due to the part variability. 1.24% of the variability of the measurement system is caused by the operator and 0.10% is due to the measuring device. To evaluate the acceptability of the measurement system, %R&R, which is one of the indicators commonly used, %P/T, which expresses the ratio of the sensitivity of the measurement system to the total tolerance as a percentage, and the Signal-to-noise ratio (SNR, which can also be expressed as the number of different categories) values, which is one of the indicators of the quality of the measurement system, were discussed. According to the results obtained from the analysis, the %R&R value is 11.56; %P/T value 9.87; SNR value was obtained as 12. Since these values have the desired values stated in the literature, it is possible to say that the measuring system is sufficient to measure the power of the tea machine
