Computer-aided quality
CAQ (of English. Computer-aided quality assurance to German computer-aided quality assurance ) is the computer-assisted determination of a quality policy and its objectives in the company and is an element of quality management . It accompanies the entire production process, with all operational and service areas. CAQ systems analyze ( process data analysis , PDA), document and archive quality-relevant data on manufacturing processes . CAQ comprises computer-aided measures for planning and implementing quality assurance .
Examples are the examination of the wheel tires of an ICE for hairline cracks or the automatic testing of integrated circuits and printed circuit boards (see also rigid needle adapter ). In addition to recording measured values, CAQ usually also includes digitization, transmission and long-term storage of the data.
The analysis, documentation and archiving of quality-relevant data is very important for companies in order to minimize the risks according to the product liability law . For this purpose, data from measuring, attributive and visual tests are evaluated by the CAQ system using statistical methods. The CAQ systems also show the process capability of production processes (see also statistical process control , SPC for short), i. H. how stable and how easily reproducible production processes are. Linking such quality-relevant data with the processing of complaints can lead to a significant reduction in costs.
CAQ is part of computer-integrated production ( CIM ) and can be exchanged between companies via QDX .
CAQ disciplines include:
- Incoming goods inspection and supplier evaluation (regulated in IATF 16949, among others ) (WE regarding English IGI)
- Pre-production test ( machine capability test ( MFU), measuring system analysis (MSA))
- Inspection during production (often in the form of statistical process control )
- Outgoing goods inspection (WAP, English OGI)
- Auditing (planning and performing audits as well as tracking the defects found)
- Impact Analysis (FMEA)
- Document management (traceability of document changes) (DMS)
- Measure management (traceability of measure implementation)
- Complaint management (traceable processing of complaints using the so-called 8D procedure; see 8D report )
- Test equipment management (proof of test equipment capability, calibration and usage history)
- Initial sample inspection (proof of the potential ability to produce the required quality)
- Quality planning (APQP)
