Need basic help

Need basic help

(OP)
Hello everybody!

My name is Roman. I'm rookie in US engineering. I studied mechanical engineering in my country (Ukraine). I see differences in standarts of drafting & other branches. So I need basic help. Can someone give me advice what literature should I choose to get required general knowledge in rules & standarts of US engineering, draftings etc.

Thank you!

RE: Need basic help

For drafting I would recommend Y14 group of standards. Maybe not exactly all of them but those which seems to be interesting for you. You will quickly notice the most significant differences in drawing formats, units, projection angle etc.

If you are interested in dimensioning and tolerancing focus especially on Y14.5.

RE: Need basic help

Presumably you're English as a second language so the standards may be challenging but I'd be tempted to say that for the drawings aspect start with the standards and then go from there.

They are expensive, perhaps a library or something has some you can look at.

If you're doing serious drafting a copy of ASME Y14.5M-**** (where **** is the edition date) may be a worthwhile investment.  As to choosing which version, a lot depends on what version your employer/potential employers adhere to.

Also, be aware, not everyone in every drafting office in the US ... fully complies with the standards.

RE: Need basic help

What's funny to me is how many people think something is in the standards (any of them) but really aren't in print anywhere (let alone the standards).  Nowadays, when I'm aware that a particular "requirement" isn't in a standard, I politely ask the person let me know where is the requirement in the standards they reference.

RE: Need basic help

The one that got me was drawing view scales. There is no standard, that I have found, that says views should be certain scales. We had it in the company standrad that views whould be 1:1, 1:2, 1:4, 1:12, etc, for inch drawings. For metric, 1:1, 1:2, 1:5, 1:10, etc.

If anyone knows of a standard that specifies drawing view scales, I'd love to see it. I get tired of seeing 31:256 as a view scale!

RE: Need basic help

There is an iso standard that says drawing scales should be multiples of 2, 5 & 10.  I'll have to get back to my office to look it up.  I take a liberal view of that and creatively come up with 4 (2 x 2), 8 (2 x 2 x 2), 25 (5 x 5), etc.  To me that was established in the pen & pencil days when people tried to scale things off the drawing despite the notes telling them not to.  I do avoid really irregular scales like 3 & 7 and definitely no 31:256!

The standards themselves are certainly definitive.  They are expensive and not particularly readable though.

You may be better served by a good drafting/drawing book.

I have earlier versions of:

http://www.amazon.com/Engineering-Drawing-Design-Cecil-Jensen/dp/0028017951

and

http://www.amazon.com/Blueprint-Reading-Basics-Warren-Hammer/dp/083113125X/ref=sr_1_1?s=books&ie=UTF8&;qid=1326910335&sr=1-1

and recommend both.

Thank u. I will start from this 2 books. To start from standards will be more harder & more expensive for me. It's wierd for me to see that standards are so expensive. When I was at home I could get all required standards for... free :) Now I see VERY BIG difference between this and that world.

Thanks all of you guys, if someone will have some tips for me, please post it :)

RE: Need basic help

Ken,
You said a mouthfull there. Shall we disallusion the guy before he starts.
frezaifua,
Were you exposed to the ISO standards in your past? Were they followed as hit and miss as the standards are here?

Please get them and send them to me :) We can work out a trade maybe?

RE: Need basic help

Roman,

Perhaps could you tell us if you are considering drafting for machinery (manufactured parts, machines, tool and die, etc...), or construction mechanical engineering (heating, air conditioning, plumbing, etc...)?

Drafting standards (or lack of them) are quite different for the two disciplines.

Good on ya,

RE: Need basic help

frezaifua, you had opportunity to get its because hard copies was company properties or even I would say authority properties. Its had  been distributed among machinery companies in whole industry.
With wind of change now national standards are not free in your home country even.

I have never used ISO standards before. I used Soviet Union standards as GOST, or my country standards as DSTU. All of u probably never heard about this type of standards. That's very old and useless standards for modern industry. That's why they are free. I just can download it for free from web.

I'm interesting in machinery, that's my goal, construction mechanical engineering can be like additional information for me.


I have another question. What program do you use to make a drafts? AutoCAD or something else? Cause I was using ASCON - Compass (russian analog of AutoCAD) while studing in college.
Also I want to ask about machines with CNC control. What kind of programming language are in use now? It's depend of manufacturer? Where can I find some instructions (commands) how to program a treatment on machines?

RE: Need basic help

Hi again Roman,

I have only been involved with construction drafting. You need advice from the other people in this forum. Their standards are much more complex and strict. In construction, we don't follow GD&T and Tolerance Analysis rules at all. I read this forum because I find it interesting. I have never posted here before.

The reason I posted this time is that I am acquainted with a fellow named Roman from Ukraine who is the owner of an HVAC contracting business. I will give him a call to see if it is a coincidence... I can provide information on standards for symbols and techniques for drafting in HVAC, Plumbing, and Electrical areas. Perhaps some examples as well.

Best of luck to you!

Good on ya,

Goober Dave

Definetly I'm not the owner of business. it is a coincidence.
May be in future I will ask about construction drafting. Thanks for help. Good luck to you too!

Do not tell nonsense. Someone from this community may lead into error with your incorrect information. Unify system of design documentation with GOST standards is valid. Some of them updated with new revision only. This background with small adaptation to American standards allow to work me as checker abroad.

RE: Need basic help

In regards to "SCALE", the Y14.100-2004 standard says:
"4.23 Scale
Scale expresses the ratio of the object size as drawn
to its full size. Drawings shall be drawn to a scale that
depicts all details of the item clearly and accurately,
except as noted in para. 4.23.3.
4.23.1 Selection of Scale.
Drawings should show an
object or assembly to full scale. When full scale is not
practicable, drawings may be prepared to reduced or
enlarged scale. It is desirable, whenever practicable, that
detail drawings be prepared to the same scale as pertinent
assembly drawings.
4.23.2 Indication of Scale.
The scale, or scales, to
which drawings are prepared shall be indicated on the
drawing. The scale to which the majority of views and
sections are drawn shall be entered after "SCALE" in
the space provided on the drawing. For multisheet
drawings, the predominant scale used for each sheet
shall be entered after "SCALE" in the space provided
on that sheet. The options for depicting scale, fraction,
ratio, or decimal are indicated as examples below. The
scale of each view or section drawn to other than the
predominate scale shall be entered directly below the
title of the view or section."

RE: Need basic help

I do not think working to older standards is all that uncommon, based on my past experience. The aerospace industry seems like it is better. I was previously employed in the machine tool industry for over 30 years and that was all old company standards that were derived from older national standards and "standard industry practices". So I am not too sure you need to feel all that different. We currently use the ASME Y14.5M-1982 standard here, I have pushed for the 1994 or 2009 but there is not much interest in change.
