Based on the research on the new three-axis linkage milling method of spiral bevel gear, the cutting motion is further simplified, and a new two-axis linkage cutting method with simpler motion control and machine tool structure is proposed. This chapter calculates and analyzes the motion relations required for two-axis linkage gear cutting. Based on the analysis of the cutting motion, the key structure of the machine tool is designed and its three-dimensional model is established. The research content of this chapter will provide a theoretical basis for the subsequent two-axis linkage gear cutting machining simulation and gear cutting experiment.
The simplified model of two axis linkage gear cutting machine tool is established by using VERICUT software. According to a specific example, the tooth blank and cutter are designed and the model is established. Based on the two-axis linkage motion analysis, the corresponding NC program for spiral bevel gear machining is compiled by using MATLAB and Excel software. Finally, the right spiral bevel gear model with 15 teeth and 9 modulus is simulated. The results further verify the feasibility of the new method of two-axis linkage gear cutting of spiral bevel gear and the designed gear cutting machine tool.
