【Abstract】 This paper is about tool path in torus tool CNC machining. The mathematical model of torus tool is established. The tool path planning algorithm is determined through calculation of the cutter location,boundary discretization,calculation of adjacent tool path and so on,according to the conversion formula,the cutter contact point will be converted to the cutter location point and then these points fit a toolpath. Lastly,the path planning algorithm is implemented by using Matlab programming. The cutter location points for torus tool are calculated by Matlab,and then fit these points to a toolpath. While using UG software,another tool path of free surface is simulated of the same data. It is drew compared the two tool paths that using torus tool is more efficient.更多还原
