The present invention relates to a system and method therefor of sorting and unloading various pieces cut from sheet blanks which have different dimensions in a sheet metal fabricating environment. To achieve this end, prior to the production run, the various program routines whose operations for effecting the cutting of the sheet blanks are retrieved and the data relevant to the to be cut pieces are grouped and analyzed so that pieces of different dimensions cut in accordance with the different program routines are respectively allocated to the corresponding sorting addresses for unloading. Accordingly, different pieces with the same dimension cut from different program routines during the same production run are unloaded to the same location of the unloader area. Optimization of the unloading process and optimal utilization of the available loading space are thereby achieved.

1. In a production process involving a plurality of nested programs, each of said nested programs cutting pieces from at least one particular worksheet having a given dimension, the layout of the pieces to be cut from said particular worksheet by said each nested program being different from the respective layouts of pieces to be cut from other particular worksheets by the other nested programs, a method of denesting said plurality of programs, comprising the steps of:reviewing all of said plurality of nested programs;retrieving data relating to each of the to be cut pieces from each of said nested programs;evaluating each of the to be cut pieces to determine a sorting address for said each to be cut piece;reorganizing the data relating to each of the to be cut pieces into a single file in accordance with the respective sorting addresses for the to be cut pieces. 2. In combination,a storage system for storing a plurality of worksheets of various dimensions;at least one sheet fabrication system for cutting pieces from any one of said worksheets;an unloading system for moving cut pieces away from said sheet fabrication machine onto an unloading area; andprocessor means for controlling the respective operations of the systems to run a production process involving a plurality of programs each to run independent of the others each of said programs controlling said sheet fabrication system to cut pieces from at least one particular worksheet having a given dimension, the layout of the pieces to be cut from said particular worksheet by said sheet fabrication system operating under said each program being different from the respective layouts of pieces from other particular worksheets to be cut by said sheet fabrication system operating under the other programs;wherein preparation of said production process, said processor means furtherreviews all of said plurality of programs;retrieves data relating to each of the to be cut pieces from each of said programs;evaluates each of the to be cut pieces to determine a sorting address for said each to be cut piece;reorganizes the data relating to each of the to be cut pieces into a single file in accordance with the respective sorting addresses for the to be cut pieces.
