Question

Set-up means creating or arranging something. In an organisation it refers as the assembly and arrangement of the things required for the performance of an operation or the way in which things are organized or arranged. In manufacturing it refers as the process of preparing a machine to run a product.

Internal Set-up

An internal setup refers to the process that is performed while a machine is stopped in order to get a machine ready to switch from one product to another.

External Set-up

External setup refers to the process that can be performed while a machine is still operating. External setup activities may be done while the process is operational as they are done outside of or away from the machine.

4 steps of setup reduction used in SMED practice

1.Classify Internal and External Steps - An internal step is one that must be performed while the machine is stopped and an external step is one that can be performed while the operation is running.

2. Convert Internal Steps to External - Reduce the time associated with the internal steps. The more setup steps, decisions, adjustments, etc should be done on external time.

3. Reduce time for remaining Internal steps - The internal setup steps and decisions need to be simple and precise while adjustments got to be reduced and eliminated as there are some Internal steps that cannot be done while the process is operational so there is need to reduce the time required to complete those steps.

4. Reduce External Setup Time - Although external setup time generally is not the constraint to the setup procedure but tools and techniques should be applied to optimize and standardize external setup time for optimal utilisation of resources and controlling cost.

Note- Kindly post the third part again as picture is incomplete and some words of parts (c) are not visible.
