3. QUALITY CONTROL Procedure or set of procedures to ensure that a manufactured product or performed service adhere to a defined set of quality criteria.

4. COMPUTER AIDED QUALITY CONTROL ( CAQC) Computer-aided quality control is when computers are used to inspect and test products that are being manufactured. It is an engineering application that can oversee the operations of machinery and ensure everything is being produced as per required standards.

5. Computer Aided Quality Control It allows for a digital inspection of the quality of the products being produced and putting in place statistical process control (SPC) and producing necessary documentation. CAQC can also ensure a failure mode and effects analysis, otherwise known as FMEA, is put into action. It can allow for advanced product quality planning and a dimensional tolerance stack-up analysis on computer-aided design models using the product and manufacturing information.

6. Objectives of CAQC Increase productivity in inspection process. Increase productivity. Reduce lead time Reduce wastage due to scrap or rework

7. Segments of CAQC Computer Aided Inspection (CAI) Computer Aided Testing (CAT)

8. Computer Aided Inspection

9. Computer Aided Inspection Computer Aided Inspection allows users to process 3D scan data and determine that all part specifications have been met. By providing graphical comparisons between CAD models and parts that can be used for first article inspection, alignment, analysis or wear, validating tooling, and both 2D & 3D geometric dimensioning and tolerance (GD&T).

10. Advantages of CAI

11. Advantages of CAI Part production is faster Products are much more accurate Comparison with the CAD Model Confirms the integrity and functionality of parts Allows to ensure the exact specification of parts No mechanical wear is encountered

12. Computer Aided Testing The application of computers to control either analog or digital test techniques in order to evaluate the quality of components and products . In this method simulations are applied to the manufactured part in which stressed, moments and other factors are applied to the part. By which strength, toughness, flexibility and endurance is checked.

13. Computer Aided Testing

14. Categories of Tests Performed in CAT Functional tests under normal and stimulated conditions Fatigue or wear tests to determine products life until failure Overload tests to determine the factor of safety built within the product Environment testing to determine how well the product will perform under different conditions

15. Advantages of CAQC Data harvesting 100% testing and inspection use of non contact sensors Computerized Feedback Control system
