NC Machining Simulation of Spiral Bevel Gear Based on VERICUT

Based on the traditional cradle-type spiral bevel gear machining theory, the mathematical model of tilt machining method for the pinion member of spiral bevel gear pair is created. Then, by applying coordinate transformation method from crade-type machine to CNC one, a five-axis virtual CNC machine model is established by VERICUT software. at the same time, the pinion cutting simulation is carried out under VERICUT according the properties of the general five-axis CNC system and the relevant configuration parameters. By using this method, the accuracy of the bevel gear cutting system based on a general five-axis CNC can be well verified.

Spiral bevel gear milling machine is one typical representative of complex manufacturing equipments. In order to simulate spiral bevel gear cutting, a five-axis virtual CNC gear cutting machine under VERICUT software is established in this paper. Based on a spiral bevel gear generating theory, the surface forming of the spiral bevel gear is studied by using coordinate transformation method in spatial kinematics, and the G-code required by actual gear cutting is generated. Then, according to the properties of the general five-axis CNC system, the machine model and the relevant configuration parameters under VERICUT is created, so the spiral bevel gear virtual NC machining system is set up. Finally, the cutting simulation and crash examination are accomplished under VERICUT. By using this method, the accuracy of the bevel gear cutting system based on a general five-axis CNC can be well verified.

Based on the traditional cradle-type epicycloids bevel gear machining theory, the mathematical model of the epicycloids spiral bevel gear machining is created. Then, by applying coordinate transformation from the cradle-type machine to a CNC one, a six-axis virtual CNC machine model is established. At the same time, the gear cutting simulation is carried out under VERICUT according the properties of the general six-axis CNC and the relevant configuration parameters. By means of this method, the accuracy of the epicycloids bevel gear cutting system based on a general six-axis CNC can be well verified. Finally, a cutting experiment is conducted.
