How does defect location work in MES software?
Therefore, we should first introduce the notion of ‘defect location’ for attribute data collection. (Think about a ‘measles chart’ where the position of each defect is marked on a drawing of the part) So, instead of recording only the presence of the defect, we will also document where it is located on the part.
When is the location of a defect important?
The examples given above show cases where the location of a defect plays a determining role in the decision to scrap or not a part. One can also imagine cases where additional information for the defect (defect length, defect area) is important for the decision.
Which is an example of a defect map?
For a glass manufacturer, an iridescence can be considered as not disturbing, if its surface does not exceed 5mm². All these examples illustrate the possibility of using a Defect Map to make the right decisions when it comes to deciding whether or not to scrap a part.
Can a defect be categorised into defect types?
Although we can monitor the defect quantities and trend, we know little else about the defect to help us understand the root cause and rectify it. The first step forward is to categorise the failures into ‘defect types’ e.g. scratches, pits, dents etc.
