During sheet metal processing, interpreting and handling measurement values is a crucial step. Comparison of these values necessitates corresponding optimizations and corrections to ensure dimensions meet requirements and adhere to design standards.

When necessary, sample testing can be employed for the statistical measurement of values. By inspecting a large number of samples, we ensure the qualified rate of dimensions.

(2) For products with abnormal measurement values, they must be re-measured and then undergo quality feedback and improvement. Additionally, timely data records and reports must be made.

During the analysis of measurement values, it's crucial to delve into the primary reasons for dimensional changes, including the manufacturing processes and transformations of raw materials, etc.
