Abstract:
1. A tool path forming method in a milling processing system, the method comprising: (A) a shape offset step of receiving an input of a shape from a user or recognizing a shape depicted in a drawing, dividing the shape into one or more shape elements, and offsetting the inputted shape; (B) shape revising steps of receiving tool information and forming an interference region formed by means of a tool angle of a tool, determining whether the interference region is formed for each of the shape elements on the basis of a shape working axis of the shape elements and the tool angle of the tool, and revising the shape elements for preventing the forming of the interference region, wherein step (B) further comprises, when the shape elements are in a straight line, and when an angle formed by the shape elements and the shape working axis is greater than an absolute value of the tool angle of the tool, including the shape elements in the interference region; (C) a closed shape forming step of making revised shapes into closed shapes; (D) a cutting surface forming step of forming a cutting surface in a processing depth direction; and (E) tool path forming steps of obtaining an intersecting point of the cutting surface and the shape elements, and forming a tool path from the intersecting point.
