Abstract
A tapping method for performing a tapping process in a punch press includes engaging a front end of a tap provided at a tapping tool attached to a rotating mold indexing device rotatably provided at the punch press with a prepared hole formed in a workpiece. When the front end of the tap is engaged with the prepared hole, a control motor of the rotating mold indexing device is rotated positively to rotate the tap positively. When it is detected that the control motor of the rotating mold indexing device has rotated a determined number of times, positive rotation of the control motor is stopped and the motor is rotated reversely, thereby to detach the tap from the prepared hole of the workpiece.
