GD&T Training: AdvancedĪn in-depth study of the principles of GD&T. You will be exposed to methods of inspection for the characteristics symbols, composite feature control frames and design exercises. The course also goes into depth on datums and datum reference frames, partial datums and datum target points. The course focuses on the geometric characteristic symbols explaining in detail each symbol, feature control frames, different modifiers and how they affect tolerancing when placed in the feature control frame. Our Geometric Dimensioning and Tolerancing (GD&T) training course covers the fundamentals and principles of the ASME Y14.5-2018 GD&T standard. This insures accurate fitting assemblies and spare parts regardless of where they are manufactured.ĭesigners, toolmakers, inspectors and project managers will greatly benefit from GD&T knowledge. GD&T is essential to ensure functional information and design intent from the assembly to its individual parts. Learn best practices for stating and interpreting dimensions/tolerances. Our GD&T courses help designers, engineers, managers, and production/manufacturing personnel to understand, create, and interpret GD&T symbols and drawings.

Just agree to make your design intent clearer in the future and leave it at that.In this on-demand webinar, certified instructor Shawn Bontaine discusses the importance of Geometric Dimensioning & Tolerancing (GD&T) and delivers an introduction tutorial on how to apply the standards. Politics is rarely an engineer's strong suit. A shared cost if you gain added benefits would be a reasonable compromise.
Since this is a tool-safe error anyway, it really is a reasonable consideration to tweak the mold along with whatever other changes may be beneficial. My opinion, the vendor should have confirmed and should fix the part. In the end, none of us will end up in court having to defend the right way to interpret ASME Y14.5 or ASME Y14.41. If this is a one off and you really don't expect future business with this supplier, you can push it harder, again, through the purchasing department. If you value this supplier, you have purchasing strike a deal and chalk it up to experience.
In the end, I find that these kind of arguments fall under the heading of "partnership agreements". Not knowing the design intent, it is difficult to know what the "right" way to define this really is. Variation of that angled face will vary significantly if the radius tolerance is even 20% of 0.5mm. In design, this is very poor control of the angled surface if its position on the diameter is indeed a design element where the overall OD is not as significant. The vendor is right in that rounds are typically calculated later and are not a critical element. In this case, I too would have put a clarifying view on the drawing or a reference dimension of the smaller diameter. The part was made using an assumption that was not factual or supported by the submitted drawing.Īll "proper" interpretations are already covered.
