Answer :
The correct answer is: dial indicators, visual reference lines, and quick-set pins.
Die position adjustments can be easily achieved by employing some techniques such as visual reference lines, dial indicators, and quick-set pins. By using dial indicators, die positions can be checked with very high accuracy. Visual reference lines may also be used for checking, but these methods may be less accurate than dial indicators. Quick-set pins are used for quick and easy repositioning of the die. One of the most critical aspects of die positioning is the determination of the correct position.
Once the position has been determined, die positioning adjustments can be done. There are several methods for die positioning adjustments, such as adjusting the die height, adjusting the die size, or adjusting the die position. Die height adjustments are achieved by adjusting the distance between the die and the workpiece, while die size adjustments are made by adjusting the width of the die.
Die position adjustments are accomplished by moving the die left, right, up, or down.
