Micro-stops
Concept
Very short interruptions of a machine, often under a few minutes, that the operator clears quickly and that often go unrecorded, but that add up to large losses of availability.
Description
Micro-stops are short interruptions of a machine that the operator clears at once, such as a jammed part, a blocked sensor or a short wait for material. Each one takes seconds or a few minutes, so many plants do not record them, or hide them in the speed of the line.
Together, though, they can cost a large share of production time. In the OEE metric they show up as lost performance rather than as downtime, which is one reason OEE can look better than reality when stops are not logged. Automatic data capture from the machine is the practical way to see them. Teams then rank the causes and remove the most frequent one first, often with simple changes such as guides, sensors or cleaning.
