A method for creating an optimal cutting plan for a strip-like material

A method for creating a revised cutting plan for a strip-like material for maximizing a quality yield of the process is invented. A cutting plan for a strip-like material is made based on end-product data. The strip-like material is driven at a production speed in a manufacturing machine or in a finishing machine, and strip length data is recorded. A chart of the strip-like material characteristics is generated and stored in a memory. The strip length data is re-measured in a winding process. The recorded strip length data and the chart of the strip-like material characteristics are fixed with a position difference, where the position difference is the difference between the re-measured strip length and the recorded strip length. During a set change between cutting patterns in the winding process the cutting plan for the strip-like material is optimized for maximizing a quality yield of the process based on the end-product data and the fixed chart of the strip-like material characteristics. The revised cutting plan is created from the optimization result.
