SC.8 Quality Control & Tolerance Flashcards
(6 cards)
Quality control (QC)
checking product against the manufacturing specifications
Quality assurance
procedures to manage all functions that affect quality (manufacturing)
Tolerance
The amount of erorr allowed for a given task. Applied to measurements, there will be specified range which is an acceptable difference between upper and lower limit.
Go/no-go
A go/no-go gauge is used to check dimensions are within specified tolerances.
Eg. When checking drill hole, if the go gauge fits but no-go gauge doesnt, the hole is within tolerance
Laser settings
Accurate process as the laser beam does not blunt or wear out. The speed, power & dimension settings must be set according to material
Seam allowance
The area between the line of stitching & edge of the fabric. Tolerance is very small so accurate stitching is needed otherwise pieces will not fit as intended
