The present invention relates to a conversational automatic programming device or the like capable of generating an NC program in a simpler manner and in a shorter period of time. The automatic programming device is provided with, a machining-profile setting processor in which based on data for specifying a geometric entity selected as a contour shape of a machined portion, out of geometric entities of a geometry defined by two-dimensional CAD data, the geometric entity corresponding to the data is recognized, and based on the recognized geometric entity, a machining profile which is the contour shape of the machined portion is set; a CL-data generating processor for generating tool path data based on the set machining profile; and an NC-program generating processor for generating an NC program based on the generated tool path data. The machining-profile setting processor corrects the recognized geometric entity and/or adds a new geometric entity such that a continuous line without bifurcation all the way from a starting point to an ending point is formable, and thereafter, sets the machining profile.

Automatic programming method and automatic programming device

A programming apparatus has a machining area recognizing section for recognizing a plurality of machining areas based on three-dimensional model data, a workpiece dividing section for setting a plurality of structures obtained by dividing a workpiece, a connection relationship recognizing section for recognizing a connection relationship between the machining areas, a machining area list generating section for recognizing, for each of the machining areas, either a machining type related to turning or a machining type related to milling corresponding thereto, and generating a machining area list in which the structures, machining areas, machining types and connection relationship are correlated with one another, a machining process setting section for setting, for each of the machining areas, a machining process corresponding to the machining type related to turning or milling thereof, and an NC program generating section for generating an NC program.
