when each parameter is vaned slightly from the optimal
setting. It can be inferred from this figure what would happen
if a process is moved to another machine which does not
behave exactly like the machine the process was optimized
on. For example, refemng to the ShearIArea graph, one can
see that moving the process to a machine with 10% lower
USG Current will result in a loss in sheadarea of I.Og/mil*.
