Abstract:
A method of generating tool movement path data for moving a machining tool and a workpiece relative to each other for machining a desired three-dimensional surface, characterized by comprising:a first constraining surface determining step of determining a first constraining surface for constraining said machining tool to machine said three-dimensional surface, said first constraining surface corresponding to said three-dimensional surface;a second constraining surface determining step of determining a second constraining surface for constraining a movement path of said machining tool, said second constraining surface consisting of a surface other than a straight surface and other than said three-dimensional surface, and intersecting said first constraining surface;an intersection line calculating step of obtaining a three-dimensional curved line equation representing a line of intersection between said first and second constraining surfaces; anda movement path data obtaining step of obtaining said movement path data including said three-dimensional curved line equation obtained in said intersection line calculating step.
