recent developments make ENGINEERING SPECIFICATIONS more realistic 590046
SPECIFICATIONS that are realistic for production and result in a product that functions properly can be set with a three-step method evolved from statistical control techniques. The tolerances thus established reduce production costs, as well as costs arising from faulty products, the author states.
The author applies the method to a leakage problem encountered on mechanical-hydraulic units. Through the use of statistical control techniques, the cause of the leakage was discovered.
