Why QC Inspectors Should Consider Gaging Fixture Spring Rates
All fixtures for part gaging will have some amount of deflection or spring rate that can affect measurement accuracy. A better understanding of spring rate can enable quality control inspectors to detect and eliminate this possible error source.
