Abstract
As for making formed sheet materials with relatively high out-of-plane bending stiffness, Nagasawa et al.(2009, 2011) investigated the stability properties of the cut profile of stacked resin and paperboard sheets. It was discussed that regardless the cutting process, the cut profile properties were influenced by the shape of the cutting edge and the tool clearance. However, the collision and friction response of the contacting surface of a sheet being fed has not been discussed regarding its profile shape. Knowing the different profile shapes (wear-burr) obtained by several cutting parameters, as well as being able to specify the dynamic sliding motion for the sheet's wear-burr profile, is necessary when determining and stabilizing failures at the time of feeding. Therefore, the objective of this work is to find a simple measurement method to specify the dynamic behavior of the profile of a PET sheet when it collides after sliding over an inclined surface. The 0.5mm thickness PET sheets that have been processed leaving a sheared profile are thrown gently to slide over a guided 45 degree slope that is set to collide against an ABS counter plate. This counter plate resisters the collision using an AE sensor that attempts to measure the impact and the sliding motion of either the wear side or the burr side of the sheet profile.
