The paper conducted a research on key position speed sensor of automobile engine size measuring tool as an example, for studying the optimization of measuring tools by using the powerful Minitab software statistics, analysis and calculation functions. It randomly selected 10 parts as a measurement sample and obtained the measurement data by experiment. It then analyzed the measured data with Minitab and calculated the repeatability and reproducibility of the device. It also worked out the causes of failure in measuring and explored how to optimize the measuring method. It finally improved measuring clamp structure, and verified its feasibility through experiments. The results show that the problem of measuring failure was solved and the measurement accuracy of the product was improved.
