This work looks at two different Design of Experiment methods for defining an operating window in the sheet metal stamping process. The first involves the use of replicates at the different experimental points while the second is a nonreplicated method. The two methods are compared by looking at the relationship results produced and the indication of variation in the process. It is found that the results from both methods are very similar. However the replicated method provides a greater level of confiden Keywords: design of experiments, operating windows, nonreplicated
