... in statistical process control
SPC (statistical process control) controls processes to detect deviations from specifications and significant changes on the operator level. Suitable measurement processes measure specified characteristics. Individual value charts, parts protocols or quality control charts show the results. The specifications depend on the respective task, e.g. the process does not exceed specified control limits or it does not exceed x% of the tolerance. In case of deviations, the operator is informed and can take corrective action.
For an easy recording of measurement results and additional data, the operator needs an input mask focusing on the current task. It thus includes all required data fields that the software completes automatically (e.g. by using barcodes or a transfer of measurement process values in real time). Catalogues provide operators with specified contents for these data fields.
