Set-Up Time Reduction

Go Back

Definition

A principle of lean thinking based on the idea that by reducing the set-up time between jobs that run on the same equipment, the overall operating efficiency is improved.

Application

Some key concepts in set-up time reduction include:

Reduction of internal set-up time. Internal set-up time is associated with adjustments that must be done to the equipment while it is shut down for set-up. In contrast, external set-up time is spent on work that can be done before the change-over starts while equipment is still running a previous part.

Standardization. Standardizing changeable parts to reduce adjustments that must be made after they are installed reduces the internal set-up time. Examples of this are standard die locator pins, shut heights and clamp locations.
