NC program search method, NC program search unit, NC program generation method and NC program generation unit

摘要

An NC program search method includes a first image generation step of generating, when shape data of a machining target is input from outside, image data corresponding to the shape data of the machining target as machining target image data; a second image generation step of generating, based on NC programs generated in the past, image data of a machining finish shape as finish shape image data; a storage step for storing the final shape image data in association with a corresponding NC program; a similarity calculating step of comparing the machining target image data and the final shape image data, thereby calculating the similarity of both image data; a search step of searching, based on the similarity, candidates of final shape image data similar to or matching the processing target image data and displaying the candidates; and a first program display step of displaying, from the candidates of the final shape image data, an NC program for final shape image data designated by the external input.
