Switching to the MasterCam CNC programming system has allowed FordMotor Company research staff to produce a wide variety of prototypeparts with complex contours on CNC machine tools rather than buildingpatterns by hand and casting the parts. The advantages have beenimpressive. 1 The need to build patterns by hand has been eliminated,thus reducing the cost of the average prototype part by 75 per cent. 2Lead time has been reduced from an average of three weeks for patternmaking, mould making and casting to a typical 48 hours for programmingand CNC machining and 3 prototype quality has been greatly improvedbecause the machined parts possess mathematically sound contours ratherthan hand filed approximations.
