How to correlate the surface quality inspection results of high-speed press stampings with the stamping process parameters?

   To correlate the surface quality inspection results of high-speed press stampings with the stamping process parameters, the following steps can be taken:
   First, during the stamping process, record in detail the stamping process parameters, such as punching pressure, stamping speed, die clearance, lubrication conditions and so on.
    When surface quality inspection results are obtained, for example, problems such as scratches and unsatisfactory roughness are found on the surface.

    Then, analyze which process parameters these problems may be related to. For example, if the surface scratches are severe, they may be related to too small a die clearance, too much punching pressure, or insufficient lubrication; if the roughness is high, it may be related to too fast a punching speed or poor die surface roughness.

Next, look for patterns and trends by comparing the surface quality of stamped parts from different batches or under different conditions and the corresponding process parameter records.
Tests and adjustments can be made to change a process parameter individually and observe its effect on surface quality to determine specific correlations.
   For example, gradually reduce the stamping pressure and observe whether the surface scratches improve to determine the specific correlation between the stamping pressure and the surface quality; or change the stamping speed to see whether the roughness changes to clarify the correspondence between the stamping speed and the surface quality.
     Through such repeated analysis, testing and adjustment, a clear correlation between the surface quality inspection results and the stamping process parameters can be gradually established, so as to better optimize the stamping process and improve the surface quality of the stamped parts.
