碩士 === 國立中正大學 === 機械工程系研究所 === 106 === The aim of this thesis attempts to explore the mathematical model of hypoid gear, which reference to the cutter design parameters of face milling system of Gleason. The blade type is mainly divided into Stick blade and Profile blade. This research involved the grinding method, comprised of analysis and improvement. In this thesis, we use Mathematica to derive the mathematical model of the hypoid gear cutter. Taking the fixed position of the cutting edge line on the sharpener coordinate system as the reference point. The pressure angle is defined by the angle between the tangent to the cutting edge line and the vertical axis. Transfer to the cutting coordinate system through calculation and find the actual cutting edge line. To project the actual edge line onto the plane of the cutting direction. Calculate the angle between the tangent and the vertical axis at the reference point as the pressure angle on the cutting coordinate system. Due to the pressure angle of the cutting coordinate system and the sharpening coordinate system will be different after calculation. The research centers on an empirical study deriving the relationship from the pressure angles on the different coordinate system, that in order to define the pressure angle parameter on the cutting coordinate system when designing the blade in the future. The differentiation of grinding method of stick blade into two-face and three-face grinding. Since the methods need to remove the blade from the cutter before grinding, and install it on the machine for sharpening. The research centers on an empirical study involving single-face grinding from grinding method of blades that it can be applied on the resharpening action of the gear cutting machine to save processing time. The analysis of mechanical process is conducted through shape of the resharpening edge and hook angle of the blade. Finally, we apply on the software program of simulating machining in order to indicate feasibility of the grinding method. To conclude, this thesis builds a three-dimensional model and machining coordinate system for grinding and cutting machines, and uses VERICUT for machining simulation, which plans the machining path and imports it into the software program of simulating machining to observe whether the interference occurs during the machining process and verify the feasibility of the grinding method.
