  • Patent number: 9411331
    Abstract: An automatic programming device includes: a machining-area-shape generation unit that generates machining-area shape data that is a machining area shape machined on the basis of machining-area data; and a chamfering tool-path generation unit that, when the machining area shape is a chamfering target part, generates chamfering tool-path data for chamfering according to chamfering data including the machining-area shape data, data on tool-to-be-used, and data on machining condition. When performing chamfering on a boundary of the shaped raw material and the machining area shape defined on a curved surface that is a shaped raw material, the chamfering tool-path generation unit generates a machining path, as the chamfering tool-path data, for realizing chamfering by using 2-axis machining of a rotating axis parallel to a central axis of the shaped raw material and with a linear axis parallel to a bottom surface of the machining area shape.

  • Patent number: 7805215
    Abstract: A programming device programs a machining control program to be used on a numerical control device for machining an object. A setting unit sets an axial direction of the tool with respect to the data on the machining-target area and sets a deepest position of a tip of the tool with respect to the data on the machining-target area. An extracting unit extracts a surface-machining-target area of the object from the data on the machining-target area based on the set axial direction of the tool, the set deepest position of the tip, and the data on the machining-target area.
