1. A numerical control (NC) hole-machining programming device which generates a NC program for hole machining based on CAD data, the device comprising:

  • 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 extracted 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.
