Machining program changing device and machining program changing method

摘要

A machining program receiving unit (11) receiving an input of a machining program is indicated; an extraction rule setting unit (12) that sets an extraction rule for extracting data of a change range from the machining program; an extraction unit (13) that extracts the data of the change range from the machining program based on the extraction rule; a modification unit (14) that modifies the data of the range of change extracted by the extraction unit (13); and a generating unit (15) that generates a post-modification processing program based on the machining program and the modification area data modified by the modification unit (14).
