PURPOSE:To maintain precision and make a production line unmanned by holding the axial end of a multi-edged cutting tool fed from a processing machine for the removal of a burr and cutting oil, and returning a size correction value to the NC device of the processing machine after the optical measurement of the outside dimensions of the tool and the classification of the measurements. CONSTITUTION:A workpiece (multi-edged cutting tool) is carried from a processing machine 1 via a feed mechanism 3 including a conveyor and the burr thereof is removed with a burr removal device 5 including a plastic brush rotating with the axial end thereof fixed on a chuck mechanism 4 such as a collet chuck. And cutting oil and the like are removed with a dust removal mechanism 10 such as a mechanism for blowing high-speed air and the outside dimensions of the workpiece are precisely measured with an optical measurement machine and the like 7 while being rotated and fed in an axial direction. A difference from a target value is returned to the NC device of the processing machine 1 as a correction value. And a defective product is discharged into a classifying member 9 and a good product into a discharge mechanism 8, thereby enabling a production line to be unmanned at a high precision level.
