Quality assurance/ control Flashcards
What is quality assurance?
Quality assurance are planned activities that ensure and monitor quality from development, manufacture, use and customer satisfaction
What are they key steps for example to do with assuring quality?
Product is fit for purpose when being developed and tested
Raw materials and components that we buy is up to the correct standards
All components and placed together correctly and are of correct quality through certain tests and inspections
Customers and stake holders receive a high quality working product that is fit for purpose and meets all expectations and requirements
What is quality control?
What are the two aspects to quality control?
Quality control is the actual activities used to ensure high quality of the product.
Inspection and testing
What does inspection mean within quality control?
An example? any one will do
Sampling and examining products to check that they are fit for purpose.
Such as a glass bottle as the correct measurement such as thickness of glass and diameter of the neck.
What are the three types of inspection?
100% inspection - all products checked
Normal inspection - used when there is no reason why the quality wont differ from the accepted level
Reduced inspection - used when quality needs to be at a sufficiently good such as on a continuous production line and when the client is confident that the quality is an accepted level
What type of inspection uses a Co-ordinate Measuring Machine (CMM)?
How does it work? What does it use to measure?
Computer Aided Inspection
It uses lasers to measure the sizes and position of components on a product with a very small tolerance.
It compares these to the design brief and if it is incorrect, the product will either be fixed or recycled.
It can even create a 3D model in CAD
What does testing mean within quality control?
What kind of condition are they carried out in?
An example? any one will do
This focuses on the materials, components and the overall products performance
Carried out in laboratory conditions to gain a fair test.
Whether the glass bottle will smash easily under a certain compression.
What are the two types of testing?
Destructive: The product is purposefully destroyed to see how it reacts.
NCAP for destructive car testing (New car assessment programme)
Non destructive: The product is tested until it starts to break to determine how much force can be applied
