Use of X-Y Plots and Simple DOE Approach to Optimize Settings on Automated Test Equipment

Summary: [This abstract is based on the author's abstract.]A statistically designed experiment is used to verify that the calibration of a pressure decay leak test for plastic parts used in antilock breaking systems is performing optimally. Calibration requires several setup parameters that can be optimized by running trials at various setup levels. Selecting a response variable that measures repeatability or accuracy validates the acceptance or rejection of parts so that final setups can be verified by measuring against known standards.
