How it works
Capacity follows from net shift time (shift length minus breaks), cycle time and the number of parts made per cycle. The OEE or efficiency factor accounts for real losses such as stops, slow running and scrap; at 100% you get the theoretical maximum.
Formula
Tnet = shift length − breaks N = Tnet / CT × cavities × OEE
For injection moulding and press tools use the number of cavities; assembly lines usually make one part per cycle. If you do not know your OEE, a value between 60 and 85% is a reasonable assumption.
