Aim To research the method of dynamic simulation about the process of NC milling machining. Methods Based on the theory of ray casting and adopting the dispersion of tools and works
a method is developed which realizes the NC milling dynamic simulation. Results It can detect the interference and collision and also can testify the deviation of the approximated tool path from the ideal surface. Conclusion The NC milling dynamic simulation in geometry has been realized. The simulation on processing still need to be researched further.
