The tools of statistical process control (SPC) are critical in understanding process capabilities, identifying unwanted variations, and refining manufacturing processes. Overall, it enables us to efficiently and consistently meet our customer’s sophisticated needs for quality, lead time, tolerances, delivery, and cost. . Robust Sheet Metal . Sheet metal stamping is also a process that can be controlled as dimensional changes could be predicted based on die life time studies. The short term capability is very good but the long term looks horible because of die wear. The process variation is fairly small and one of the biggest factors is variation in sheet metal thickness. The question is, how do production managers and process engineers help to avoid these problems and help reduce waste on the shop floor or assembly line? Perhaps the best approach is to minimize process variability—and that is accomplished by studying and isolating problem areas and gathering data. Enter statistical process control, or “SPC.”(b) Produce the X ˉ control chart.

Statistical process control (SPC) charts are one of several tools used in quality control. The SPC quality control tool has . Introduction. Statistical Process Control (SPC) is a method designed to monitor and control product or process variability using statistical tools. The main idea is that it is less expensive to check the quality of products or processes by periodically examining a small sample rather than inspecting every single product. Additionally, in situations where the testing method . A framework for monitoring and control within automotive sheet metal forming is proposed that addresses the current limitations through the use of real-time production data and reduced process models and reflects the significance of the presented framework in transitioning to the digital manufacturing paradigm.
