Program editing assistance device

Abstract

The present invention provides a technology with which the degree of freedom in setting an indexing angle can be increased, within a range in which interference is avoided, in the creation of a program for controlling the operation of a machine tool. A program editing assistance device 10 comprises: an analysis unit 11 that generates, from a program, command data including at least a prescribed position of a prescribed point on a movement path of a tool 20, and a relative indexing angle between the tool 20 and a workpiece W at the prescribed position; a tool shape acquisition unit 12 that acquires shape information of one or more components which constitute the tool 20; a range calculation unit 13 that calculates, on the basis of the command data and the shape information, an indexing angle range in which the workpiece W and the tool 20 do not interfere with each other at the prescribed position; and a presentation unit 14 that outputs the indexing angle range.
