摘要： A preceding-check processing sequence is provided separately from a machine-control processing sequence for an actual machine control, to make it possible to perform a collision check at an accurate position from an operation restart time of a machining program even when an operator interrupts an operation in the middle of the machining program or when the operator interrupts the operation as having detected a collision. This preceding-check processing sequence performs a collision possibility check ahead of an actual machine control. In this arrangement, there is provided a control-state synchronizing unit that matches a state of the preceding-check processing sequence with a state of the machine-control processing sequence during a period from when a machine stops until when the machine restarts an operation.

摘要： An interference checking device includes a contour shape analyzing unit 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 analyzing unit that obtains a rotation center of the rotating tool by analyzing the contour shape, a three-dimensional-rotation-shape generating unit that generates a three-dimensional shape of the rotating tool on the basis of the contour shape, the tool length, and the rotation center, and an interference check processing unit 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, in which the three-dimensional-rotation-shape generating unit generates the three-dimensional shape by using a left-side contour shape.
