Abstract
The objective of the present study was to analyze the shearing characteristics of a resin sheet by a straight punch and dies. In this paper, in order to reveal the die clearance effect and the feed velocity effect on the sheared end-profile of deflection resin sheet which was attached with protection films, a precision shear testing device was developed. Shearing of the deflection resin sheet was experimentally carried out by varying the die clearance and the feed velocity of punch. The surface layers of deflection resin sheet were observed with a de-laminated state of protection films. Furthermore, the shear strength was discussed with the properties of the resin sheet.
