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.
A method for creating a revised cutting plan for a strip-like material for maximizing a quality yield of the process, wherein a first 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, and a chart of the strip-like material characteristics is generated and stored in a memory, wherein 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 calibrated with calibration data in the winding process, where the calibration data is the difference between the re-measured strip length data and the recorded strip length data, and during a set change in the winding process the first 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 the revised cutting plan is created from the optimization result.
A method according to 10, wherein the strip-like material to be optimized comprises at least one of the following:
A non-transitory software product data recording medium in which program code is stored, which program code will cause a computer to perform a method for creating a revised cutting plan for a strip-like material for maximizing a quality yield of the process, wherein a first 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, and a chart of the strip-like material characteristics is generated and stored in a memory, wherein 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 calibrated with calibration data in the winding process, where the calibration data is the difference between the re-measured strip length and the recorded strip length, and during a set change in the winding process the first 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 the revised cutting plan is created from the optimization result.
