Dimensioning Slots Asme
Readers will learn:
The standard for dimensioning and tolerancing was revised in 2009. ASME Y14.52009 now replaces the 1994 version. However, each company makes the decision as to when their new designs will begin to use the new standard. The title block or a general note should always be used to clarify which standard is being imposed on a given drawing. In the next section, we will elaborate on the use of slots for overcoming the overconstraint problem through a sample part using geometric dimensioning and tolerancing principles defined by the ASME standard. Use of Slots – A GD&T Example As we saw earlier, slots allow us to avoid overconstraint while having greater precision.
1. To tolerance flexible parts.
2. The difficulties in fixturing and inspecting flexible parts to collect repeatable measurement data.
3. About free state variation.
4. That part should be inspected in the way that they function.
5. To apply temporary datum features for in-process inspection.
6. Common misconceptions regarding the tolerancing and inspection of flexible parts.
7. The criteria for selecting datum features on flexible parts.
8. The “free state” symbol and what it means.
9. How to write a “restrained state” note.
10. That all parts are to be measured in the free state, unless restraint applied does not distort measurements, or unless a note is written to allow inspection in the restrained condition.
11. To dimension and tolerance a fixture for simulate datum features for inspection.
