What is changeover time in production?
In manufacturing, changeover is the process of converting a line or machine from running one product to another. Changeover times can last from a few minutes to as much as several weeks in the case of automobile manufacturers retooling for new models. Set-up is only one component of changeover.
What is changeover time in lean?
Changeover is the time it takes to go from the last good part of one product run to the first good part of the next product run. Quick changeover is critical to Lean. It provides the flexibility to match the product mix to actual demand.
How do you calculate changeover time?
Basically the time to change is divided by the number of pieces run until the change is needed. In the video example the changeover time is 600 seconds for 50 pieces so 12 seconds per piece is added on to cycle time.
Why is changeover time important?
Effects on Manufacturing Productivity Reducing changeover time unlocks more productive (value-added) time for running production. Another benefit is that by reducing changeover time you can reduce production batch sizes, work-in-process (WIP), and inventory.
What changeover means?
a conversion or complete change from one thing, condition, or system to another, as in equipment, personnel, methods of production, etc.: a changeover to automated equipment.

The entire changeover time also includes clean-up procedures for the previous run as well as start-up procedures for the next run.
How is the changeover time of a part measured?
Changeover time is measured from the last good part of the current part run to the first good part of the next part run. The fastest path to improved changeover times is typically through non-technical improvements, such as creating standardized work instructions, marking down known settings on equipment, and displaying real-time metrics.
How to reduce changeover time in a project?
It was also found that scheduling components of the same product so that they are produced in the same time period reduces the overall changeover time of the product. Lastly, applying the rank order clustering algorithm reduced the number of tool and fixture changeovers.
Which is the fastest way to improve changeover times?
The fastest path to improved changeover times is typically through non-technical improvements, such as creating standardized work instructions, marking down known settings on equipment, and displaying real-time metrics.
