Many people will want to stone me when they read this. Because these lines destroy a world view.
The previous chapter briefly showed the planning of subgroups. If the scope is "2", then this picture looks like this:
2/moving has its raison d'être! This is the case when the components are so large that it is not possible to set up a warehouse with 5 components in front of the measuring room. End of the list of justifications.
However, if 2/moving is used as the subgroup size, it must be understood that the basic principle of the subgroup has not been adhered to: Within a subgroup, all components must be produced consecutively, from the same machine, from the same gage, operator.... And so on. This is not the case with the "sliding" process. It should therefore only be used if there is no other technical possibility.
This also means that alarms of any kind should be viewed critically!
