Since each machine was highly automated, the operators39。 Case 2: To improve stamping（沖壓） capacity, a specially designed grabbing（抓） device (an iron hand) was installed to take the stamped part out of the machine quickly, utilizing the upward moving force of the machine. With this arrangement, the upward force, which in itself does not add value to the product, is now bined with the work of the iron hand. Since this device was designed to reach the part even before the upper die reached the highest point of its stroke, additional stamping capacity was gained. “ECRS”四大原則q R: Rearrange，重排。s time. But simple solutions can often be found to eliminate adjustment work. If die height was standardized so that setup was much simpler, then eliminate the adjustment process. The same idea may be applied in other areas such as eliminating horizontal adjus
