OK.
So, what exactly, is going through the oven?
What is happening to what's going through the oven? Is it being dried? Is it being cured? Else?
What measure of product quality is affected most by variations in oven operation?
At 1200mm/min, how long does each part reside in the oven?
How else is the oven instrumented? (What other data is available)?
What constraints, if any, are there during the normal course of operation (that could damage the oven or render the product useless)?
Do you have any test data from an unloaded oven (no product throughput)?
