PURPOSE:To conduct the positioning of a processing tool and a work with a high precision and increase the working efficiency by conducting positioning from an outcome detected by means of two optical axes so that the relative position of the reference position of each of the processing tool and the work may become a desired size. CONSTITUTION:An optical device 5 which possesses an optical axis which can be changed into two directions opposite to each other on the same straight line and which picks up the images of both of a work 1 and a processing tool 3, is inserted between the work 1 and the tool 3. Next, the reference position of the processing tool 3 is detected by means of one optical axis of the device 5, and at a position set previously from the reference position of the tool 3 thus detected, the reference position of the work 1 whose image is picked up by changing the optical axis of the device 5 into the other optical axis, is positioned. Afterwards, the optical device 5 is drawn out of a space between the work 1 and the tool 5, and the work 1 and the tool 3 are made to approach each other and processing is conducted. |
