Abstract
The present invention relates to a method and apparatus for adjusting the weight of workpiece by twice machining a weight-adjustment portion formed on the workpiece. In the present invention, the same cutting tool is used for machining the weight-adjustment portion and the feeding position for the second machining of the weight-adjustment portion is determined in response to the weight of the workpiece after the first machining. According to the present invention, even if the tips of the cutting tool should wear because of prolonged machining operations and, as a result, the amount of the first machining is insufficient, the said insufficiency is compensated for by the second machining.
