Abstract:
1. An automatic cutting device comprising: a stage for a base material to be placed upon; a cutting tool; an image sensor which has an image capture region; a tool shift mechanism for, with respect to said stage, shifting said cutting tool, changing an angle of said cutting tool, and moreover shifting a photographic region of said image sensor; and a controller which controls an operation of each of said cutting tool, said image sensor, and said tool shift mechanism, according to an NC program; wherein said controller comprises: a first cutting sub-process control means which, according to said NC program, performs control so as to execute a first cutting sub-process of cutting said base material which has been placed upon said stage with said cutting tool and cutting out a manufactured product; an image capture control means which, after said first cutting sub-process has been executed, performs control so as to set said image capture region of said image sensor to at least a single region which includes proper positions of at least two peculiar points upon said manufactured product, which has been cut out, upon said stage which are defined by said NC program, and so as to acquire from said image sensor an image of said at least a single region; a peculiar point detection means which analyzes said image of said at least a single region which has been acquired by said image sensor, and detects actual positions on said stage of said at least two peculiar points of said manufactured product which has been cut out; a program correction means which corrects said NC program so as to match it to the actual position of said manufactured product, which has been cut out, on said stage, according to said actual positions of said peculiar points which have been detected; and a second cutting sub-process control means which, according to said corrected NC program, performs control so as to execute a second cutting sub-process of performing additional cutting with said cutting tool upon said manufactured product, which has been cut out, on said stage.
