FMEA, Six Sigma, Taguchi and process capability
What is the difference between 3D scanning and CMM and classical measurement? Comparison on the axis of accuracy, data density, speed and surface constraints; Which one should be chosen for which job?.
What is process capability (Cp/Cpk)? We explain the difference between a part being 'passable' and the process being repeatable with an example calculation..
What is Taguchi robust design? We explain the logic and loss function of making the product resistant to field variability, not laboratory conditions..
What is FMEA (failure mode and effects analysis)? We explain with an example the method of predicting failures at the design stage by quantifying the risk with RPN..
