Resumen
THE USE OF MACHINING SYSTEMS BY COMPUTER NUMERICAL CONTROL (CNC) HAS NOTABLE ADVANTAGES IN THE AREA OF INDUSTRIAL PRODUCTION COMPARED WITH TRADITIONAL TECHNIQUES. THIS FACILITATES A SIGNIFICANT DECREASE OF TIME, HIGHER PRECISION AND OPTIMIZATION OF OPERATION PARAMETERS. THE CONTROL OF SEQUENCES IN THESE SYSTEMS IS BASED ON CODES THAT DEFINE THE PARAMETERS TO PRODUCE THE MACHINING OF A DETERMINED PIECE. HOWEVER, THE GENERATION OF THESE CODES PRESENTS TWO MAJOR CHALLENGES, FIRST, KNOW THE TRIDIMENSIONAL INFORMATION OF THE PIECE TO PRODUCE, AND SECOND, DEFINE THE SEQUENCE BY CNC MACHINING. IN THIS WORK, THE FRINGE PROJECTION TECHNIQUE IS USED TO OBTAIN THREE-DIMENSIONAL INFORMATION FROM AN OBJECT AND BASED ON THIS INFORMATION, AUTOMATICALLY GENERATE PROGRAMMING CODES FOR THE MACHINING ROUTINE OF A THREE-AXIAL CNC MILLING MACHINE. THE RESULTS ARE COMPARED TO APPLY THE FRINGE PROJECTION TECHNIC TO RECOVER THREE-DIMENSIONAL SHAPE OF AN OBJECT BASED ON LEAST SQUARES ALGORITHM, USING INFORMATION FROM THREE TO EIGHT IMAGES.
