**Workshop Exercise 6.3 - Datum Feature Exercise** The part below includes various features labeled as datum features. Assume all are primary datum features, and the datum features of size apply at RMB. For each datum feature in the table below, identify whether it establishes a point, axis, plane, or a combination of these datums. Also, list the names of translational (x, y, z) and rotational (u, v, w) degrees of freedom constrained by the datum feature. Refer to the isometric view on the right for the labeled degrees of freedom. **Diagram Explanation:** The diagram includes an isometric view of a mechanical component with features labeled from A to J. These features indicate datum points, axes, and planes. The component includes specific dimensions, such as: - Dimension A: Ø 0.682 ± 0.002 - Dimension B: 0.600 ± 0.004 - Dimension C: 0.600 ± 0.002 - Dimension D: 0.300 ± 0.002 - Dimension E: 2X Ø 0.250 -0.002 +0.005 - Dimension F: Ø 0.005 **Table:** | Primary Datum Feature | Established Datum | Constrained Degrees of Freedom | |-----------------------|-------------------|--------------------------------| | | | Translations (x,y,z) | Rotations (u,v,w) | | 1. A | 3 | x | v, w | | 2. B | | | | | 3. C-E | | | | | 4. D | | | | | 5. F | | | | | 6. G | | | | | 7. H | | | | | 8. J | | | | **Discussion:** Some of the datum features may be too unstable (short in length) to be a primary datum feature and constrain all the listed degrees of freedom. Identify which ones they are. **Note:** This exercise helps understand how datum features are used to define and constrain the movement of parts in engineering design. The isometric view aids in visualizing the spatial relationships and constraints applied through these datums.

Question
I need help filling out this chart. The part below has a variety of features that are labeled at datum features. Assume all are primary datum features and the datum features of size apply at RMB.
Next to the datum feature in the table below, identify if it establishes a point, axis, plane, or some combination of these datums. Also list the names of translational (x,y,z) and rotational (u,v,w) degrees of freedom constrained by the datum feature.
Please refer to the attached image for the graphic and table.

The part below includes various features labeled as datum features. Assume all are primary datum features, and the datum features of size apply at RMB.
For each datum feature in the table below, identify whether it establishes a point, axis, plane, or a combination of these datums. Also, list the names of translational (x, y, z) and rotational (u, v, w) degrees of freedom constrained by the datum feature. Refer to the isometric view on the right for the labeled degrees of freedom.
**Diagram Explanation:**
The diagram includes an isometric view of a mechanical component with features labeled from A to J. These features indicate datum points, axes, and planes. The component includes specific dimensions, such as:
- Dimension A: Ø 0.682 ± 0.002
- Dimension B: 0.600 ± 0.004
- Dimension C: 0.600 ± 0.002
- Dimension D: 0.300 ± 0.002
- Dimension E: 2X Ø 0.250 -0.002 +0.005
- Dimension F: Ø 0.005
**Table:**
| Primary Datum Feature | Established Datum | Constrained Degrees of Freedom |
|-----------------------|-------------------|--------------------------------|
| | | Translations (x,y,z) | Rotations (u,v,w) |
| 1. A | 3 | x | v, w |
| 2. B | | | |
| 3. C-E | | | |
| 4. D | | | |
| 5. F | | | |
| 6. G | | | |
| 7. H | | | |
| 8. J | | | |
**Discussion:**
Some of the datum features may be too unstable (short in length) to be a primary datum feature and constrain all the listed degrees of freedom. Identify which ones they are.
**Note:** This exercise helps understand how datum features are used to define and constrain the movement of parts in engineering design. The isometric view aids in visualizing the spatial relationships and constraints applied through these datums.
