The research content provides a reference for improving the cutting efficiency of spiral bevel gear milling machine, reasonably selecting the main motor power, optimizing the cutting processing parameters and reducing the residual height of spiral bevel gear tooth surface. However, due to the complexity of spiral bevel gear tooth surface geometry, meshing process, design and processing process and the limitation of experimental conditions, there are still some problems to be further studied and improved.
(1) The research on the cutting force of spiral bevel gear small wheel has not yet gone deep into the hypoid gear small wheel (tool inclination method or denaturation method), and this research will continue to be carried out in the future. For the hobbing method, the variable feed rate control method under the constraint of basically constant cutting force should also continue to be studied.
(2) Based on the milling force monitoring of spiral bevel gear NC milling machine, an intelligent monitoring system for the milling process can be established to monitor tool wear and cutting vibration, which is of great significance to improve the intelligent production of spiral bevel gear milling machine. At the same time, it also provides a more accurate dynamic external load for the fatigue life design of key parts such as main shaft bearing and transmission shaft bearing.
(3) The optimization of cutting parameters of NC gear milling machine and the residual height control algorithm of spiral bevel gear surface are integrated with the closed-loop manufacturing system of spiral bevel gear. Using visual programming, an intelligent cutting parameter optimization module of NC gear milling machine is established, which can improve the function of the closed-loop manufacturing system.
