Closed-loop manufacturing (abbreviated CLM) is a closed-loop process of manufacturing and measuring (checking) in the manufacturing machine. The pre-stage to this is inspection in manufacturing. The idea is to reduce costs and improve the quality and accuracy of the produced parts.
In machining measurement techniques have to fulfill special needs. In particular optical techniques have the advantage that they do not touch the part. The following parts are practically used:
Measuring can be more accurate because the part does not need to be unloaded
Better deployment of personnel
Integrated sensor eliminates clamping errors
The disadvantages are:
Planning is needed
If planning is not done, machine time is increased
