GD&T, datum strategy, tolerance stack-ups and MBD/PMI, reviewed to ASME Y14.5, ISO GPS and BS 8888.
Work in this sector is confidential by default; what we can show is what a review finds, and the magntitude associated with what finding it early is worth.
Over-constrained or unbuildable datum reference frames, datum features no fixture can simulate, and DRFs that ignore assembly function. The datum scheme is the backbone; get it wrong and every measurement downstream is contestable.
Position applied RFS where MMC belongs, forfeiting bonus tolerance the design already paid for. Fixed and floating fastener conditions verified by calculation, not habit.
Profile of a surface with no fully defined true profile, missing basic dimensions, and title-block defaults doing work they cannot do under ASME Y14.5 or BS 8888.
Conforming parts that will not assemble indicating the stack-up was incorrectly determined, not the parts.
Callouts that are geometrically legal and unverifiable as drawn: CMM-contestable measurements, uncontrolled degrees of freedom, and first article inspection (FAIR, AS9102) exposure baked into the definition.
Model-based definition where the PMI contradicts the drawing, STEP AP242 exchange that strips design intent, and digital datasets a supplier's CAM and CMM cannot consume.
We help prevent the compounding effects, downstream concerns and engineering disputes that can emanate from front end engineering design and propagate throughout the process until final inspection.
One definition, one interpretation, three functions aligned. Lower costs, less time wasted, improved quality; fewer failures.
The engineering drawing, or the model that replaces it, is the contract between three functions. Design writes it, manufacturing prices and makes to it, quality verifies against it.
Most cost leaks through the seams between the three.
A GD&T-led design assurance review closes the seams: one definition, one interpretation, evidence a design authority, a machinist and an inspector all accept.
Quality assured at the source, not inspected in at the end.
Every review we conduct is embedded into the respective & applicable full definition stack: ASME Y14.5, ASME Y14.41, ISO GPS including ISO 5459 datum systems and ISO 16792 digital product definition, BS 8888, and STEP AP242 data exchange.
Reviews are led by a holder of the ASME GDTP Senior certification, the highest level of the ASME Geometric Dimensioning and Tolerancing Professional credential, alongside Chartered Quality Professional standing.
