Numerical-control-program editing apparatus, numerical-control-program editing method, and program

A numerical-control-program editing apparatus comprising:

• a machining-shape generating unit that generates, for each unit of machining, a three-dimensional machining shape including position information in a three-dimensional virtual space based on attribute information, which is dimension information or position information described for each unit of machining configuring a numerical control (NC) program;
• an attribute processing unit that extracts the attribute information from the NC program and associates three-dimensional position information corresponding to a machining shape corresponding to the extracted attribute information with the extracted attribute information;
• and
• a display-screen control unit that displays the NC program on a program display screen and displays, on a shape display screen, a projection drawing in which the machining shape arranged in the virtual space is obliquely projected according to the position information contained in the machining shape, and when receiving an input for editing the NC program via the program display screen, reflects content of the input on the NC program, wherein
• the display-screen control unit displays the extracted attribute information in a position indicated by position information associated with the attribute information on the shape display screen, the position being on the projection drawing and adjacent to a portion of the machining shape corresponding to the extracted attribute information,
• the machining unit configuring the NC program includes a unit of machining in which position information of a start point and an end point of a track of a tool is described as attribute information, and
• the display-screen control unit displays, on the shape display screen, a shape of the track of the tool using an arrow directed from the start point to the end point.
