NEW TEST METHOD FOR DETECTION AND ANALYSIS OF BURRS AND SLIVERS IN TRIMMING AND PUNCHING ALUMINIUM SHEET METAL
Last modified: 2014-11-24
Abstract
A large problem when trimming or punching aluminium sheet is the creation of burrs and slivers which degrade the quality of the produced parts. A semi- industrial test for evaluating trimming of aluminium has been further developed to include pre-stressing and pre-straining of the sheet material before trimming. The semi-industrial test results now show good correlation to industrial production outcomes.
