PROBLEM TO BE SOLVED: To provide an interaction region setting method of a machine tool equipped with a tool rest on which a chuck to grip a workpiece and a tool are fixed, in particular a turret tool rest, capable of easily performing without error the setting operation of the interaction region for avoiding collision of the tool with the workpiece or the chuck grasping it. SOLUTION: The loci of the region occupied by the chuck and the workpiece and the region occupied by each tool corresponding to the movement of the tool rest for each indexing position of the turret are computed from the coordinates of the tool rest when a contact sensor 2 mounted on the tool rest is put in contact with a plurality of places on the chuck surface and the workpiece surface and the coordinates of the tool rest when the tool and a tool holder fixed to the tool rest are contacted in different directions with a contact sensor mounted on the spindle side, and the position of the tool rest when the tool collides with the chuck or the workpiece is computed by checking the interaction of those regions.
