This dataset focuses on analyzing the correlation between backlash and repeatability of optical dial couplings, and reveals the quantitative relationship between transmission system backlash and measurement repeatability. It provides critical decision-making support for the company (as a manufacturer) and external stakeholders, and holds substantial application value. The specific manifestations are as follows:
1. Optimize product development and production processes: The company can leverage the correlation analysis data between backlash and repeatability of optical dial couplings to provide a basis for optimizing coupling selection and assembly processes, thereby effectively improving the measurement stability of the dial and reducing the risk of measurement errors caused by transmission backlash.
2. Promote scientific and technological progress in the industry: This dataset can serve as a reference for relevant researchers, technical R&D personnel, quality management staff, product inspectors and other practitioners in the fields of precision transmission and optical measuring equipment, and support their work such as transmission system optimization, repeatability prediction analysis, trend analysis, causal relationship exploration, quality control, scientific research and technical optimization, so as to facilitate industrial technological development and product quality improvement.
1. Data Collection: Real-time recording of the repeatability test data of optical dial couplings under various backlash conditions, including fields such as test sample number, test time, coupling backlash / μm, repeatability / arcsec, etc.
2. Data Preprocessing:
(1) Perform denoising processing on the collected data to ensure data accuracy.
(2) Aggregate the historically collected data (including this batch of collected data) to form dataset X, and calculate the average value of the repeatability field in dataset X.
3. Correlation Coefficient Calculation:
(1) Based on dataset X, use the CORREL function to calculate the Pearson correlation coefficient r between coupling backlash and repeatability.
(2) The value range of the correlation coefficient r is [-1, 1]. The closer its absolute value is to 1, the stronger the linear correlation between the two variables; the closer its absolute value is to 0, the weaker the linear correlation between the two variables.
4. Result Application: If |r| ≥ 0.8, it is judged as "strong correlation"; if 0.5 ≤ |r| < 0.8, it is judged as "moderate correlation"; if |r| < 0.5, it is judged as "weak correlation".
