WebOct 23, 2024 · Non-diametrical tolerance zone, only using the one basic associated with the slot width. Only select the one axis when creating characteristic. To get MMC, you need to create a theoretical circle lying between the two planes of the slot width. The theoretical circle will be used for your TP characteristic, and you can apply MMC. Web4: Length is a perpendicular .Len (whichever side of the slot is more controlled - Usually a slot has two position controls, one for length and one for width, so I'm not sure which the case is for you, since they just call profile, not position. From that, you will have a feature of size that you can use as a datum.

WebA datum feature can be a plane, line, or point, which needs to be used selectively depending on the tolerance and feature you need to specify. This page explains the … WebBoth of the datums are defined at RMB (Regardless of material boundary). This part is still underconstrained: The specifications allow rotation around B since there is no datum C to stop the rotation (there could have been a slot or a keyway). Underconstrained + Maximum Material Boundary Modifier on Datum B (Figure 3, Right)
WebA datum axis is then established using the related actual mating envelope (something like the largest pin that will fit datum feature B that is at right angles to the first datum plane). … WebUse of Slots – A GD&T Example. As we saw earlier, slots allow us to avoid overconstraint while having greater precision. An example of this can be seen in Figure 3. Figure 3. Part with slot tolerances applied (Primary …
