摘要： Provided is a technique capable of inexpensively working a steel sheet. A method for working a workpiece with an apparatus for working a workpiece, includes: a drawing step for performing drawing with a drawing device having an upper die and a lower die; and a cutting step for cutting the drawn workpiece with a cutting device having nibblers. The nibbler has a cylindrical case, a punch housed in the case, which reciprocates in a top-bottom direction to punch the workpiece, and a die arranged below the case, the die having a die hole into which the punch enters, and an ejecting hole communicating with the die hole, through which a scrap is ejected. The nibbler trims the workpiece fed between the case and the die.
