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. The motion relations required for two-axis linkage gear cutting are calculated and analyzed. 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 rationale for the subsequent two-axis linkage gear cutting machining simulation and gear cutting experiment.
Based on the research on the new method of three-axis linkage milling of spiral bevel gear, a new method of two-axis linkage point milling with simpler cutting motion is proposed, the motion of two-axis linkage cutting is analyzed, and a two-axis linkage cutting scheme is designed. Finally, the simplified three-dimensional model of the key mechanism of the spiral bevel gear two-axis linkage cutting machine tool is established by using CATIA software, and the movements required in the process of cutting the tooth surface of the spiral bevel gear are analyzed, which preliminarily verifies the feasibility of the key mechanism of the designed cutting machine tool.
