Application 09/927,281
a steady blade;
a clamping pad securing the blank to said steady blade;
a moving blade movable past said steady blade for trimming the
blank, said moving blade moving substantially perpendicular to an upper
surface of said blank;
a radius formed on the leading edge of said moving blade adapted to
reduce defects in the blank associated with the trimming process; and
a support element in communication with the scrap and adapted to
reduce defects in the blank associated with the trimming process, said
support element moving substantially perpendicular to said upper surface.
12. A method of reducing the production of defects during trimming
operations comprising:
holding a blank between a steady blade and a clamping pad;
moving a moving blade past said steady blade to trim scrap off of said
blank, said moving blade moving perpendicular to an upper surface of said
blank;
supporting said scrap to reduce defects in said blank associated with
the trimming process;
keeping said scrap substantially parallel to said scrap’s original
orientation during the trimming process; and
reducing the strain concentration caused by said moving blade on said
blank through the use of a radius formed on the leading edge of said moving
blade.
