ASME Y14.5-2018 GD&T Standards: Datums, Position Tolerances & Material Condition Modifiers
Implementing rigorous Geometric Dimensioning and Tolerancing (GD&T) principles to define functional manufacturing limits without costly tolerance stackups.
Advanced Dimensional Management, GD&T Tolerance Stacking & Statistical Process Control
Empowering quality and mechanical engineering teams with Advanced Dimensional Management (ADM), automated GD&T tolerance stackup calculations, and real-time Statistical Process Control charting.
Engineering Specifications
Statistical Tolerance Synthesis: Root Sum Squares (RSS) vs Monte Carlo Variation Simulation
Comparing linear Worst-Case analysis against Root Sum Squares (RSS) and 3D Monte Carlo statistical simulations to balance quality against manufacturing cost.
Shewhart Control Charts: X-bar/R, X-bar/S, EWMA and Nelson Rules for Sub-Zero Defects
Deploying real-time automated statistical process control charts on plant floors to detect special-cause variation before non-conforming parts are produced.
