Y14.5 is now ASME Y14.5M and is parts of the series of ASME Y14 books. Mil standard 100xx got combined into ASME Y14 series of standards.
Be warned that mis-reading a print for dimension or tolerance is probably very large on the list of things that go wrong.įor reference, ANSI Y14.5M does not exist any more. A lost part is not a failure, it is an education that we go through. Frustration kills more ideas than anything else. It is part of the learning curve, training the mind to rule the hands. Make another from some more bits and get it to work.
It is wise to start with a small project and finish the its, and bits, that are mostly bar stock, and if its junk. The In/Out process of sketching it out can help to better understand the needs in finishing the part, (castings are notorious for being a little 'off' if not carefully laid out before the metal hacking is started). Some times a change can be caught before it takes root in the physical part and makes it scrap. One trick I use on parts with confusing dimensions, is to take a rule and caliper and sketch out the part in hand, and compare it to the official drawing. Dimension lines and notes on the keylist (if it has one) will become more understood as you learn about machining, and the requirements of centers, fit and finish. Mostly tho, the fog will clear as you make simple things, and find the keys to reading a drawing right there in your head. I think the best way I can answer you is to get a high school level book on mechanical and archetectural drawing, that is meant to teach us farm boys where to put a line on paper.ĭrafting and Drawings, are the foundation of making parts from scratch, and if a drawing is not clear, you will be quickly lost in the woods.
