Statistical Process Control for Press Control 3000

The software package SCHMIDT® SPC is used for determining the process capability. The program calculates the statistical parameters from the process and tolerance data. The characteristics of all quality criteria are calculated online after each assembly process, and the calculation is available for documentation. Contrary to conventional systems, the user is constantly informed about the trend of the assembly and the process quality. User-defined upper and lower warning and intervention limits inform the process control when exceeding or falling below these limits about which application-specific measures can be taken.

In the overview display, you see all necessary information from the process, such as characteristics (monitors), information pass/fail, current measuring value, SPC status, average value, Cp and Cpk value, at a glance..
 
Each single process can be reconstructed using the production history.

 
Considering the individual characteristics, additional important values are displayed graphically and numerically.

Apart from the system-related monitors, other process-relevant information can be extracted statistically, such as the work integral (area under the F/s curve) or external measuring data (e.g. temperature).
