  • Method and apparatus for preparing data on tool moving path, and machining method and system
    Patent number: 6311098
    Abstract: Method of generating tool movement path data 9 includes determining a tool constraining surface (12) which is offset from a three-dimensional surface (22) to be generated, by a distance equal to a radial dimension of rotary machining tool (20), in a direction normal to the three-dimensional surface, determining tool path constraining surfaces (32) for constraining the tool according to the geometry of the three-dimensional surface, and obtaining three-dimensional curved line equations representing intersection lines (34) between the constraining surfaces (12, 32). Since desired curved surfaces may be used as the tool path constraining surfaces (32), the tool movement path can be suitably determined with high freedom depending upon the geometry of the three-dimensional surface (22) to be generated.
