Metrologically assisted machining - technology watch note

In a classic machining process, the parts after machining are taken out of the machine tool to be checked. In the event of a deviation from the specifications, and if a rework is possible, the part must be re-mounted on the machine, which generates positioning uncertainties, which can lead to the impossibility of producing a compliant or acceptable part without having analysed the correlation between the specified product characteristics beforehand, thus resulting in the rejection of the part produced.

Metrologically assisted machining consists in integrating measurement as early as possible in the process of machining parts using a machine tool.
