To improve the machining efficiency and reduce the overall manufacturing cost, a new model of machining hypoid gears by tilt cutting method is setup. Unlike the traditional cradle-style mechanical machines, the new model has no cradle and eccentric drum, the tool swivel drum is controlled by NC system. Firstly, according to its special structure, the mathematical model of the machine tool is built, an algorithm is developed to calculate the motional parameters. After building the machine tool

... del by the software Vericut, cutting simulation is performed. Based on the comparison of gouge and excess amount between simulated model and theoretical model, the tooth cutting experiment is conducted. Then, measurement and rolling detection for the hypoid gears is performed. The results indicate the rationality, reliability and accuracy of newly designed model of the milling machine. Moreover, the proposed method of calculating the motional parameters is feasible, which would be meaningful for future industrial application.
