Abstract Free-form milling is a flexible gear machining method that allows using general disc cutters to machine various gear types on a 5-axis machine tool. This paper proposes a two-dimensional simulation method for free-form milling of cylindrical gears with disc cutters. A mathematical model for free-form milling of cylindrical gears with disc cutters is constructed. By analyzing the spatial positional relationships between the cutter and the workpiece, the instantaneous contact line is derived and projected onto the gear end face, and then the projected curves are intersected to obtain the final profile. This calculation method realizes the rapid simulation of the actual cutting condition on the gear end face, which is beneficial to the judgment of machining interference and the analysis of the tooth profile accuracy during the gear machining process.

Engineering designs often come upon with steady mooring problems in a wide range of port with submerged breakwater. Plane physical model is difficult to implement due to spatial limitation and, so far, there is no effective numerical method to solve practical engineering problems by two-dimensional simulation. This paper first verifies the empirical formulas for transmission coefficient of submerged breakwaters in domestic and international researches against the results of sectional physical model. The verification shows that the calculated results with the empirical formula of Yang (1981) are the most consistent with the measured data and a bit conservative. Based on Yang’s formula, porosity coefficient is used to simulate the integrated effect resulted from the physical features of overtopping, wave transmission and reflection on a prototype submerged breakwater. Then a plane physical model test is carried out to verify the simulation and the results are in good agreement. This paper provides an effective numerical simulation method for wave protection of ports with submerged breakwater.
