Since it is impossible to avoid the production of defects in many manufacturing film coating applications, there is significant value in cutting the film in a manner that reduces both trim waste as well as final defective product that is produced. This paper describes a software application that seeks to reduce the amount of defect waste produced, and minimize inspection of final product, through making use of: (1) information about the quality of a master roll; (2) a set of constraints and rules describing how best to achieve minimum waste and minimum need for additional inspection; and (3) a set of cut widths for production based on customer orders. As a result of using the application, henceforth called the Converting Optimizer, a cutting strategy is identified that can reduce final product waste and minimize the need for final product manual inspection.
