Abstract
According to the model of the freeform surface, which is represented by the Double Cubic B-Spline Surface, the method of changing parameters is used to calculate the NC machining tool path. The formula of calculating cutter location data which consider of the compensation of both tool nose radius and tool swing radius of the flying cutter is deduced. The cutting experiment of machining a freeform progressive optics lens in a multi-axis ultra-precision machine tool shows that the collision free tool path can be produced by the developed tool path generator.
