Abstract

A NOVEL SOLID MODELING METHOD WILL BE APPLIED TO THE PROBLEMOF THE VALIDATION OF THE INPUT PROGRAM FOR NUMERICAL CONTROLLED (NC) MACHINES. THE PROJECT WILL PROVIDE AN EFFICIENT AND ECONOMICAL MECHANISM TO GENERATE A 3D GRAPHICAL EMULATION OF NC MACHINING, PROVIDING DIMENSIONAL INFORMATION AND CHECKS FOR UNDESIRED TOOL/SPINDLE/FIXTURE/WORKPIECE COLLISIONS. MULTI-AXIS TOOL MOTIONS AND A SPECTRUM OF MILLING TOOL GEOMETRICS WILL BE ACCOMMODATED. IN ADDITION, AN AUTOMATED VERIFICATION CAPABILITY WILL BE CREATED. THESE PROGRAMS ARE FEASIBLE DUETO CERTAIN SPECIAL FEATURES OF THE PROPOSED SOLID MODEL SYSTEM, PARTICULARLY A CAPABILITY FOR VERY FAST BOOLEAN OPERATIONS.
