Question

Question 8 The shortcoming of the undefined measurement setup can be eliminated by this: The datum system coordinate tolerancing system zero fixed-size tolerance zone. Square tolerance zone. دا A Moving to another question will save this response.

Answer 1

solution 8- Datum system ---> Geometric tolerancing eliminates the shortcoming of undefined measurement setup by using a concept called The Datum Systemthat allows the designer to define the measurement setup for the inspector.

solution 9-Accumulation of tolerance .---->GD&T allows for material modifier , which allow for upto sevreal hundred percent increase in tolerance ,reducing manufacturing difficuty even more while maintaining interchangibility requirements.

solution 10- plane surface--->. Everything is comprised of Features. But note that features are always things that we can touch. In GD&T the term feature-of-size (FOS) refers to any surface, or set of parallel surfaces associated with a size dimension . So the hole (at its surface) is a feature. The axis of the hole is not a feature. Likewise a slot is a feature, but the center-plane of the slot is not a feature.
