Today will be a short article continuing on where we left off last week when we covering the Limits of Size. Section 2.7 of ASME Y14.5-1994 only relates to the Limits of Size and limits of size do not control the orientation or location of features. Section 2.7.3 goes into detail about this and we will quickly examine the contents of this section today.

We are back this week with some more ASME goodness after taking a short break. This week is all about Tolerance Accumulation per Section 2.6 of ASME Y14.5. You maybe asking yourself right now, “What is Tolerance Accumulation?”. Tolerance accumulation, or tolerance stack-up, is the dimensional variance between two features of a part based on the tolerance range of the intermediate dimensions. How you apply dimensions and tolerances to features on a part can have a huge effect on the finished part. Today we will look at some simple parts and how different methods of dimensions can give you dramatically different results.

Last week I started covering Section 2 of ASME Y14.5-1994, General Tolerancing and Related Principles, with the post Standards Wednesday - General Tolerancing Pt1. This week we will continue to explore this section of the ASME Y14.5 with Section 2.3, Tolerance Expression; Section 2.4, Interpretation of Limits and Section 2.5, Single Limits. Section 2 is a pretty hefty section and it will take us a few weeks to go through but we really need to cover it before we move on to GD&T.

Another Wednesday is upon us and it’s time for another installment of Standards Wednesday. This week we get to jump in right into Section 2 of ASME Y14.5, General Tolerancing and Related Principles. If you are new to Standards Wednesday, let me explain it to you. Every week I take a different part of an ASME standard and do my best at breaking it down into easy to understand English and try to relate it to SolidWorks. Over the last couple of weeks I covered Section 1 and if you missed anything, I highly recommend going back and read them…they were pretty good.

Woo-Hoo! Another Standards Tuesday and I am so excited. I hope you have been looking forward to this week’s installment as much as I have been. Last week we began looking into Section 1.8, Dimensioning Features, of ASME Y14.5M-1994 and judging by the traffic it seems to be the most popular Standards Tuesday yet. If you missed it, make sure you go back and read Standards Tuesday - Dimensioning Features Pt1.Today we will continue discussing dimensioning features per ASME such as irregular outlines, spotfaces & knurling. So without any further a due, let us jump right in.
