OPTYLD - A Multiple Rip-First Computer Program to Maximize Cutting Yields.

Abstract : This paper describes the computer program OPTYLD that is designed to simulate multiple rip-first, then crosscut, then rerip operations-operations as practiced by softwood moulding and millwork industries. This program can be useful in studying yield of individual boards, yield of board grades and grade mixes, effects of alternatives rip widths on yield, effects of defect scanning equipment, and effects of alternative cutting bills. The program has been written in FORTRAN V and processes on the University of Wisconsin's UNIVAC 1110 computer. The complete program listing is included as an appendix. (Author)
