ABSTRACT:
A numerical control (NC) hole-machining programming device includes: a tool information storing unit for storing tool information, including types and sizes of tools used for hole machining; a form recognizing unit for extracting a cylindrical surface and conical surface as a local geometry which constitutes a hole-machining form of target objects based on CAD data; a machining method determining unit which generates a hole-machining-form pattern based on the hole-machining form detected by the form recognizing unit and determines machining methods based on the hole-machining-form pattern; a tool determining unit for selecting a tool in accordance with the machining methods determined by the machining method determining unit with reference to the tool information; a tool path determining unit which determines a tool path for each tool selected by the tool determining unit; and an NC program generating unit which generates an NC program based on the tool paths determined by the tool path determining unit.
