The system 10 includes a conveyor 12 for carrying the workpieces (WP) to be trimmed prior to subsequent slicing of the workpiece past a scanning system 14 for scanning the workpiece WP to ascertain the physical characteristics of the workpiece, including, for example, its three-dimensional shape as well as its position on the conveyor. A cutting station 16 trims the workpiece WP into a desired two-dimensional shape which represents an optimum shape for the workpiece that seeks to maximize the harvest of slices from the workpiece while maintaining a desired quality level for the slices. A slicing station uses high speed cutters or slicers for portioning/slicing the workpiece into portions/slices which have been simulated by a processing system 18 employing a processor or computer 20. ## Claims ### Claim 1 A control system for controlling a system for trimming a stream of three-dimensional workpieces while being conveyed on a conveyor system for dividing the trimmed workpieces into multiple final pieces based on designated physical characteristics of the final pieces, the conveyor system transporting the workpieces past a scanner apparatus for scanning the workpiece to obtain electronic data regarding the physical characteristics of the workpiece and past a cutter for trimming the workpieces, the control system comprising: generating a three-dimensional model of the scanned workpiece from the electronic scanner data;
