A base (2) is fixed to a work table (31) of a machine tool (30). By adjusting the position of a mounting member (3) corresponding to the base (2), the position of a work (W) fixed to a mounting surface (3a) of the mounting member (3) is adjusted. The work (W), together with an X-axis moving table (43) of the machine tool (30), is moved by a very small amount in a state where a test indicator (46) mounted on a tool head (44) is brought into contact with a work surface (Wa) of the work (W). An operator grasps an inclination of the work surface (Wa) relative to the X-axis while seeing the displacement of a pointer of the test indicator (46). When a first execute switch (67) is turned on after an amount of correction required to cancel the inclination is manually set by a first correction amount adjusting switch (64), first driving and fixing members (4A, 4B, 4C) drive the mounting member (3) by an amount contributing to cancellation of the inclination of the work surface (Wa) relative to the X-axis. An inclination of the work surface (Wa) relative to the Y-axis is corrected by the same operation, to correct an inclination of a plane (Wb) perpendicular to the work surface (Wa) relative to the X-axis (Fig. 1). <IMAGE> |
