It provides important decision-making basis for the company (as a manufacturer) and external stakeholders, and has significant application value, which is specifically reflected in the following aspects: 1. Optimize product development and production processes: By analyzing the impact of CTE uniformity on line uniformity, the company can precisely control material preparation processes, optimize heat treatment schemes, scientifically formulate thermal stability control standards and quality parameters, and improve the stability of scale line quality of products under different temperature environments. 2. Promote scientific and technological progress in the industry: This dataset can be used by relevant researchers, technical R&D personnel, quality managers, product inspectors and other personnel in the field of precision instrument manufacturing, providing support for their work such as material thermal stability research, scale line process optimization, quality control and scientific research. 1. Data Collection: Real-time recording of test data on the line uniformity of optical dial scales under different CTE uniformity conditions, including fields such as test sample number, test time, coefficient of thermal expansion uniformity (%), and line uniformity (%). 2. Data Preprocessing: (1) Denoise the collected data to ensure data accuracy. (2) Aggregate the historically collected data (including this collection) to form dataset X, and calculate the average value of the line uniformity field in dataset X. 3. Calculation of Linear Regression Slope a and Intercept b: (1) Based on dataset X (with CTE uniformity as the independent variable and line uniformity as the dependent variable), use the SLOPE function to determine the slope a based on the principle of least squares, and use the INTERCEPT function to determine the intercept b. (2) The slope a represents the degree of influence of unit CTE uniformity change on line uniformity, and the intercept b represents the line uniformity value of the optical dial scale under the reference CTE uniformity. 4. Result Application: (1) Calculate the proportional coefficient k: k = |a / average line uniformity| × 100%. (2) If k ≥ 10%, it is judged as "high impact"; if 5% ≤ k < 10%, it is judged as "medium impact"; if k < 5%, it is judged as "low impact".
