Based on the actual motion data of spiral bevel gear NC machining machine tool, the spiral bevel gear machining process and machining environment are simulated, so as to establish the three-dimensional motion model of spiral bevel gear NC machining machine tool, and show its machining forming process in a three-dimensional dynamic graphical way, which can not only help gear designers and manufacturers check the possible problems in design and machining in the laboratory, At the same time, it can also effectively verify the correctness of spiral bevel gear NC machining code, and greatly reduce the working time of expensive NC gear machining equipment occupied by trial cutting. In addition, by using the simulation and Simulation of the spiral bevel gear machining process, we can also discover in advance various dangers that may occur in the spiral bevel gear NC machining process, such as the collision and interference between the cutter head and the gear blank, the cutter head and the fixture, and the cutter head and the workbench, Before the actual processing, the possibility of damage to the NC processing equipment and system caused by human factors in the actual gear processing process will be minimized.
Therefore, using the spiral bevel gear tooth surface forming motion simulation function technology, using the computer to simulate the real spiral bevel gear tooth surface forming motion process, to verify the reliability of the spiral bevel gear tooth surface forming motion NC program, and to predict the spiral bevel gear tooth surface forming motion process, is one of the more effective methods to improve the spiral bevel gear tooth surface NC machining efficiency.
