ABSTRACT
One-step defect-free changeover refers to an approach for setting up the machine for the next product in such a way that the machine produces high-quality goods, starting with the item The step is to think about the reasons for the adjustments in the light of the principles and standards of the process. In contrast, one-step defect-free changeover means changeover with zero adjustments. In many cases workplaces have achieved one-step defect-free changeover, only to drift back into old patterns with the passage of time or with a turnover in personnel. Like the standards for autonomous maintenance, the standards for one-step defect-free changeover should be clearly defined and rigorously maintained. When the central processing position of the work piece was made uniform, the strokes also became uniform, eliminating the need for adjustments. Finally, maintain and manage the new standard by following autonomous maintenance standards to reduce variability in equipment conditions, tracking changeover conditions, and monitoring tool precision on an ongoing basis.
