摘要：

The ultra-precision flycutting machining is usually used to machine large-size planer optical elements used in laser systems. Due to the comprehensive influence of different factors, the ripples on the optical surface will reduce the laser damage threshold, thus affecting the application of the laser system. A simulation model of the surface stripes in ultra-precision flycutting machining is built in this paper, which utilizes the advantages of simplicity and accuracy. The influences of cutting parameters, cutting interference phenomenon, relative vibration between the tool tip and the workpiece, workpiece shape, rotation speed fluctuation, and workpiece offset are analyzed. The formation mechanism of the ripples along the cutting direction and the feed direction is thoroughly explained. The ultra-precision flycutting machining test verified that the simulated and the experimental surface ripples agree well, which verifies the accuracy of the simulation model. The simulation model can be used to optimize the cutting process of the ultra-precision flycutting machining, which avoids the time and money consuming in cutting experiments and can also provide new ideas for tracing the source of the waviness on the surface topography.
