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

摘要

A method for creating a cutting plan for a strip-like material for maximizing a quality yield of the process is invented. In the method a cutting plan for a strip-like material is made based on end-product data, and 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 recorded strip length data and the chart of the strip-like material characteristics is calibrated with calibration data in a winding process, and during a set change 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 calibrated chart of the strip-like material characteristics, and a revised cutting plan is created from the optimization result.
