I have recently been tasked with scrap reduction in my manufacturing cell. The reason for most our scrap is through vendors, and we are currently working with them to reduce the levels. In any event, one main scrap contributer in our plastics division is inclusions/subsurface defects (voids, burnt resin ,etc...). Any visual defect is immediately scrapped if on a bearing surface. The problem is, a lot of these defects are not visually noticeable until the device is milled. Does anyone know of any processes that could identify the location of these defects? I would like to be able to scrap these components prior to accumulating the value associated with machining.
Thanks
