Based on the establishment of the simplified model, gear blank model and tool model of the gear cutting machine tool, call the sin840d control system built in VERICUT, and add the prepared NC machining program to the NC program file of the simulation machining project tree. Finally, the milling simulation of spiral bevel gear can be realized by clicking the control simulation button. Finally, the number of teeth is 20 Right spiral bevel gear with module 8, as shown in the figure.
The VERICUT simulation results of spiral bevel gear milling show that the designed three-axis linkage cutting machine tool can realize the cutting motion of spiral bevel gear tooth surface required by the tooth surface generation line cutting method; In the whole process of cutting the tooth surface, there are no phenomena such as interference, collision, over cutting and under cutting of the tooth surface, which proves the correctness of the NC machining program; Finally, the spiral bevel gear model is cut, which proves the feasibility of the new method of spiral bevel gear three-axis linkage cutting proposed in this paper.
