Quality Control and Reporting

What is 3D Quality Control and Reporting?

3D Quality Control and -Reporting is the evaluation of produced parts by using 3D measurement systems such as optical scanning systems, laser scanning systems, probed arms, coordinate measuring systems (CMM) and many more.

3 Boyutlu Kalite Kontrol Nasıl Yapılır?

Boyutsal kalite kontrol günümüzde birçok ölçü aleti ile yapılmaktadır. Genellikle her imalat atölyesinde bulunan konvansiyonel ölçü aletlerinin (kumpas, mikrometre, mihengir vs.) dışında 3 boyutlu koordinat ölçüm sistemleri (CMM – Coordinate Measuring Machine) ve 3 boyutlu tarayıcılar ile de yapılmaktadır. Tarama sistemleri ile parça taranarak nokta bulutu datası elde edilir. Elde edilen nokta bulutu data çeşitli yöntemlerle ( Best-fit, RPS, 3-2-1 vb.) çakıştırıldıktan sonra nominal data ile arasındaki farklar incelenir. Burada kullanılan belli başlı yöntemler aşağıdaki gibidir. 3 boyutlu tarama sistemleri ile elde edilen poligon data ile kontrol uygulaması klasik kalite kontrol uygulamalarından çok daha faydalı sonuçlar verebilmektedir.

Advantages

Advantages of Quality Control and – Reporting

  1. 3D scanning systems are able to perform 100% control as they obtain complete data of an object
  2. The whole piece is controlled by overlapping the part with original CAD data or polygon mesh data of the original part
  3. 2D GD&T or 3D GD&T applications can be used to measure all dimensions
  4. Deflections on the surface of the part can be observed quickly by analyzing point deviations
  5. The deviations of the part can be observed and interpreted in reporting
  6. All measurements can be automatically repeated for the next series of parts in much shorter time
  7. SPC (Statistical process control) can be performed between measurements
  8. Measurement report is easier to understand because it represents the object’s visual shape

Important Factors to Consider

Critical Factors of Quality Control and – Reporting

  1. The accuracy of the measuring device has to be more accurate than the part’s tolerance
  2. The measurement equipment must be certified
  3. The measurement should be made with the appropriate technology for the part
  4. The received report should not be at the user’s discretion
  5. For pre-series measurement, more than one part needs to be measured (depends on the number of parts produced)
  6. Flexible or moving parts must be measured on a fixture
  7. It is very unlikely to process oil/ liquid substances with 3D scanning systems
