Method of generating cutting passes of complex curved surface

摘要

A complex curved surface (SS) is divided into a plurality of areas (ARj), a vertical relationship regarding a plurality of curved surfaces (SSi) present only in each of the areas is specified for every area, the vertical relationship conforming to an area (ARj) in which there exists a line of intersection (CLk) that is a projection of a cutting pass on an X- Y plane is used to obtain cutting passes (Pak) of the complex curved surface in this area (ARj), and the cutting passes of the complex curved surface are generated by combining the cutting passes of all areas (ARj).
