a control-command generating unit configured to generate, based on the third machining shape and the input execution order, a control command for causing a machine tool to operate.

2. The automatic programming apparatus according to claim 1 , wherein the second machining shapes for each of the machining processes generated by the machining-shape generating unit include a machining shape machined by rough machining, a machining shape machined by wall finish machining, and a machining shape machined by bottom finish machining.

3. An automatic programming apparatus comprising:
a machining-process-data generating unit configured to generate second machining shapes for each of machining processes from each of an externally-input plurality of first machining shapes;
a machining-shape adjusting unit configured to extend, among two of the second machining shapes having tool directions different from each other, the tool directions being directions that a tool is fed during machining, among the second machining shapes, when a bottom surface section of one machining shape of the two machining shapes is in contact with the other machining shape, the bottom surface section of the one machining shape in the tool direction of the one machining shape, delete, from the other machining shape that overlaps the one machining shape because of the extension of the one machining shape, a portion of the overlap, and generate a third machining shape; and
a control-command generating unit configured to generate, based on the third machining shape, a control command for causing a machine tool to operate.

4.

5. The automatic programming apparatus according to claim 3 , wherein the machining-shape adjusting unit deletes, when a ratio of a portion where the one machining shape and the other machining shape overlap on a plane of the one machining shape perpendicular to the tool direction to the other machining shape is larger than a predetermined value, the overlapping portion from the other machining shape and does not delete the overlapping portion when the ratio is smaller than the predetermined value.

6. A control command generating method comprising:
a machining-shape generating step of generating second machining shapes for each of machining processes from each of a plurality of first machining shapes input from an outside;
a machining-order editing step of receiving an input of execution order of the machining processes;
