OEE Calculator
Availability times performance times quality. Enter one shift and the three losses separate themselves, so you know whether you are losing time, speed or parts.
Ideal cycle time is the fastest the machine has ever run a good part, not the rate on the quote. Planned production time excludes time you chose not to run; everything else you lose is downtime.
World class is often quoted as 85%. Ignore the benchmark and watch your own trend. A machine that is not the constraint does not need a high OEE, it needs to be available when the constraint calls for it.
