How to detect the surface quality of metal sheet after processing?

Firstly, high-precision processing equipment should be selected and calibrated and maintained regularly. Before processing, the raw materials should be strictly inspected to ensure that their dimensions and performance meet the requirements. Reasonable processing techniques should be formulated, and the optimal processing parameters should be determined through process tests. During the processing, the operation should be strictly carried out in accordance with the process regulations. After processing, precise measuring tools and detection equipment, such as three-coordinate measuring instruments, should be used to inspect the parts. If the parts exceed the tolerance range, they should be adjusted or reworked in time.(sheet metal fabrication)
