Abstract:
A method for evaluating sheet-type work material carried on a cutting table support surface to minimize waste, said method comprising the steps of:providing a cutting apparatus having a movable support surface adapted to carry at least one layer of sheet-type work material, a camera and cutter head amounted to said cutting apparatus, said camera and said cutter head being movable over said movable support surface and defining an offset distance between a tip of said cutter head and a focal point defined by said camera, said camera movement defining a scanable area and said tip movement defining a cuttable area within the scanable area, the offset distance creating an ancillary area; presenting said work material to said support surface, a portion of said work material within said scanable area; selecting an origin point on said portion; positioning said focal point of said camera over said origin point; causing said camera to scan at least part of said portion of said work material within said scanable area thereby generating a first set of data; relocating said moveable support surface and thereby said work material such that at least some of said at least part corresponding with said first set of data is positioned within said ancillary area and additional work material is within said cuttable area; scanning at least part of the said additional work material within said cuttable area to generate a second data set; and performing a cutting operating in said ancillary area and said cuttable area in accordance with said first and second sets of data.
