Abstract: A machining program creating apparatus includes a tool-route generating unit sequentially executing, concerning each line segment, processing for setting an end point of a set tool route as an endpoint of interest and setting a line segment connected to the endpoint of interest as a next tool route and an NC-machining-program-creation processing unit creating the NC machining program. When a line segment not set as a tool route yet is present among line segments connected to the endpoint of interest, the tool-route generating unit sets the line segment not set as a tool route as a next tool route, and, otherwise, the tool route generating unit sets a line segment already set as a tool route as a tool route again between the endpoint of interest and an endpoint forming a line segment not set as a tool route yet.

In addition, a length of the recessed edge which cannot be machined in each tool direction is evaluated. A machining program for machining is created from the tool direction where the machinable area is the maximum and the length of the recessed edge which cannot be machined is the minimum.
