Checklist: quality assurance of series
How to ensure that many identical items are actually identical and correct
Quality assurance in a series is about catching deviations early and watching along the way. An error found on the first item costs one item; one found at the end can cost them all.
§At series start
- 01Measure the first part thoroughly according to the drawing
- 02Confirm that setup and programming give the correct result
- 03Correct the setup before you continue if something is different
§Along the way.
- 01Measure a part at regular intervals
- 02Keep an eye on signs of worn tools that change the result
- 03Stop and examine if the items begin to deviate
§At the end
- 01Check a sample of finished items
- 02Sort any defective items out
- 03Note what was inspected and any deviations
