Abstract:
1. An interference checking device comprising: a contour shape analyzer that extracts a contour shape of a tool cross section and a tool length by analyzing a two-dimensional image of a rotating tool; a rotation center analyzer that obtains a rotation center of the rotating tool by analyzing the contour shape; a rotation shape generator that generates a three-dimensional shape of the rotating tool on a basis of the contour shape, the tool length, and the rotation center; and an interference checker that checks whether the rotating tool and a component other than the rotating tool interfere with each other when numerical control machining is performed on a workpiece by using the rotating tool, by using the three-dimensional shape, wherein the rotation shape generator generates the three-dimensional shape of the rotating tool by using a left-side contour shape, which is a contour shape on a left side of the rotation center in the contour shape, and a right-side contour shape, which is a contour shape on a right side of the rotation center in the contour shape.
