How would you annotate that two ends of a bent plate are level to each other. For instance, the top of the letter V, the ends at the top are level to each other. Any suggestions?
-
I would suggest a datum line - and the elevation noted

Thank you! I have been meaning to study up on datums...guess now's the time. :lol:
-
I am thinking the symbol for straightness? I have a V shaped plate and the tops are level once it is placed.
(The things paying for my education would get me!!! :|)
-
to be clear....
-
My V shaped plate looks like the "not this" one. :lol: I am required to draw them as they are made and that is how it is made. 8-)
-
then your 'straightness' symbol would be incorrect....a it would imply the 'this' condition.
Perhaps best to define the angle of that plate, and the angle at which it is mounted about it's center line
as well as the elevation of the bottom
-
The more you know, the easier it is to think outside the box. :lmao: Excellent!! Thank you mj!

Bethrine,
You nominate a 'Bent plate'
How is it bent ?
I assume the vertex will NOT be sharp as you have depicted. It is physically impossible to 'bend' plate with a sharp vertex.
Plate is bent with an internal radius that translates to the outside. The minimum effective radius is determined by the thickness and material.
Regarding dimensioning ..
What is the critical criteria ?
.. the horizontal distance between inside corners ?
.. the enclosed angle ?
.. the overall height ?
.. the leg distance ?
.. the internal radius ?
.. the plate length prior to bending ?
that is what you want to dimension.
added:
Regarding annotation.
The object will be symmetrical about the vertical centerline ? yes ?
-
Perhaps it is an extrusion and not bent?
-
Words have meaning Bob.
:-)
-
Whoops Sorry
Or you could describe it by the process: "Grind ends level to each other as shown".

Bethrine,

I assume the vertex will NOT be sharp as you have depicted.No. It is physically impossible to 'bend' plate with a sharp vertex.Agreed

.. the enclosed angle ?
.. the overall height ?
.. the leg distance ?
.. the internal radius ?
see pic for the needed dimensions of the above
.. the plate length prior to bending ? I also have a flat pattern annotated with additional measurements not noted in the below piccy
that is what you want to dimension. :-D
added:
Regarding annotation.
The object will be symmetrical about the vertical centerline ? yes ? yes
The second annotation object is for assembly and is where I would like help (although I am never against good advice). mj, did I do that right? I've been all over the net on datums and, well, yuck.
The arrow cut off to the left is a callout.
-
looks good, only thing that could be added would be symbol for symmetry about CL
-
IN your second screen capture I would add a vertical dimension from your bent plat back to the other assembly/part; so that you can control height after installation, especially if you are welding the parts
-
Thought you might like to see what got approval. Mostly due to the ability of the shop guys to interpret it. :grazy:
-
Bethrine,
You may want to use decimal degrees.
the 36 degree leg setout does not match the 109 enclosed angle ;-)
.... Mostly due to the ability of the shop guys to interpret it.
That's what counts, and is sometimes very easy to forget in the pursuit of technical excellence.

Bethrine,
What sort of beastie is this you're building ?

Bethrine,

Ohhh Ohhh I know what it is!
It is a Rewinder!
It is a Rewinder for a Duck's Butt!
Something has to wind that waddle. And Bethrine has the designed the new and improved Duck's Butt Rewinder 4000

You only said that cause it mentioned mounting a bottom. Or something like that...

Nope. Good effort but wrong!
-
Exactly right, it's a rewinder mount. :evil:
The guys on the floor fabricate stuff that "works" and I take it apart and draw it up so it can be sent out and made in quantity. Any more info than that and I'd have to kill you. :pissed: We literally do backwards reverse engineering here.
-
:ugly: We literally do backwards engineering here.
Love it! Instead of Design-Build, it's Build-Design!
-
That's a mis-quote: This guy -> :pissed: went with the "I'd have to kill you" part. I love my job!!! :love:
-
Wouldn't you mean reverse engineering as opposed to just doing things the wrong way (backwards)?

Ok fixed it in my post.
I "appeared" to be with this sentance so I kept it :whistle:
Your job sounds awesome! Hiring?

You after my job?? Think 110 degrees most of the year. :-P :lol:

Ok you win!
I'll stay up here in Maine where we have 21 days of summer and 6 months of winter.
:realmad:

Yech! My Mom's side of the family is in Minnesota. No thank you! :ugly:
...did I just help hijack my own thread??

> 110°F is nothing compared to Mexicali, where there can be 59°C/138°F -- brrrrrrrrrrrrrr :ugly:

Seriously you just dissed Minnesota? Se7en! Hey Se8en! You hear what she said about Minnesota!
You want me to sick our ex governor on you?

And sort of dissed Maine too (I think)..
Wait, ...what?
You can HAVE our Governor!! He's a tool

They are both beautiful states and I have a lot of fun when I visit Minnesota. The cold, however, is not something I am accustomed to. I freeze at 73 degrees. Seriously, my teeth chatter.
-keep the governor...

LOL, I've been down to Disney World (Florida) in December with my family (quite a few years back)..
And all the "natives" working there where wearing jackets, gloves and hats,
..and we were wearing shorts, sandals and pullovers and they looked at us like we were aliens.
It was a bit cool, but a treat from what we left in Maine.
It was probably 60 degrees that day in Florida, but 15 degrees in Maine.
Last winter was brutal though.. wished I lived in Florida then.

I used decimal degrees on the flat pattern and fractions for the rest. (Also approved for ease of use).
Sure doesn't, does it. :doa:

Don't apologize. The snowbirds that I know, wear that term with great pride and chest thumping. One Snowbird told me it was either be called a snowbird or be called a swinger. :lol:

Yeah, 'The Villages' retirement community in Central Florida supposedly have the high STD rate in the nation. Not that i've checked it out personally mind you....

Guess now I know the real reason.
