Abstract
A method for selectively relieving sharp edges in tools used in die cutting web or sheet-type work material which includes providing a machining apparatus for supporting the tool thereon, where the machining apparatus includes a rotary cutter mounted thereon and moveable relative to the tool. The method also includes providing a controller having machine readable shape data corresponding to at least one of the tools stored therein, and operating the controller to determine, responsive to the stored shape data, locations of edge segments defined by the tool against which the work material will impinge as the work material is advanced onto the tool in a first direction. In addition, the method includes causing the controller to generate a machining path, which when followed by the cutter will relieve the edge segments, and operating the machining apparatus to cause the cutter to follow the machining path in response to command signals generated by the controller, thereby relieving the edge segments and preventing the work material from catching on the tool as it is advanced thereon.
