PURPOSE:To improve the accuracy in positioning by providing the work positioning jig movable in parallel in the coordinate axial direction for a work table and arranging the NC control device performing the storage of the movement amt. of the jig and the reading of an original coordinate as well. CONSTITUTION:The work positioning jigs 6, 7 moving in parallel in X axial direction and Y axial direction respectively on a work table 1 are provided and the NC control device storing the moving amt. of the jigs 6, 7 and capable of reading the original coordinate of a work 5 as the intersection point thereof is provided as well. In case of performing the positioning of the work 5 a work head is first moved to an original point. The jigs 7, 6 are then moved and after storing the movement amt. to a control device moved to a refuge position. The work head is thereafter moved to the stored original point 8 of the jigs 6, 7 to process the work 5 according to the program. Owing to the positioning at the work starting point becoming correct the positioning accuracy is improved. |
