| Summary: | 碩士 === 國立中正大學 === 機械工程學系暨研究所 === 99 === The objective of this study is to develop a hypoid gear cutting simulation methodology on a general-purpose five-axis CNC machine tools based on the SolidWorks API and the motion control computer program. The cutting motion setting conversion is transferred from the classical cradle hypoid generator coordinate to the modern CNC hypoid generator and general-purpose five-axis CNC machine tools. The mechanism of cradle-type, modern hypoid generator, and the general-purpose five-axis machine tools were modeled by SolidWorks API and the relative spatial movement between mechanisms is controlled by the G-code generated by the motion control computer program. The relative motion between the cutter and workpiece is defined by the G-Codes and the overlap part of the workpiece and head cutter will be removed from the workpiece by the SolidWorks API substrate Boolean function. Then the solid model of the generated hypoid gear can be created to verify the correctness of the cutting motion conversion. Several numerical results were presented to verify the correspondence among the classical cradle-type, modern CNC hypoid generator, and universal five-axis machine tools. The proposed methodology can be used to verify the cutting motion control G-code before real gear cutting and check the collision between cutter and workpiece. The material removal rate during the cutting process can be obtained by the SolidWorks API and the feed rate can be optimized to increase the cutting efficiency and the solid model of finished hypoid gear can be used in the further FEM analysis.
