We can see that we can then react to the manufacturing process before manufacturing non-conforming parts. Non-quality is then anticipated, and not suffered a posteriori.
This technique can be applied to any manufacturing process, whether you manufacture small or large series, whether you do 100% inspection or sampling.
It can be seen that the potential gains from applying this methodology are enormous.
Initially initiated by the automotive industry, for which it was vital not to measure all the parts (because of the very large production runs), the technique gradually spread to other sectors such as the medical and aeronautical industries, and more generally to the manufacture of parts with very high added value.
In the latter case, all parts continue to be measured, but thanks to the SPC technique, control can be lightened, and reducing the rate of non-conformity means reducing the number of reworkings, concessions etc.
Qual@xy SPC, Infodream’s SPC software, has been developed with this in mind, i.e. SPC software should be accessible and of interest to all.
