ABSTRACT:
A method and apparatus are provided for reducing or eliminating sliver formation during aluminum sheet trimming operations. A resilient support pad is used in the trimming apparatus to substantially eliminate the formation of slivers which damage the surface finish of the part. Use of the resilient support pad also significantly reduces burr heights and improves trimmed edge quality. The method and apparatus are particularly useful for trimming aluminum autobody sheet.
