My adventure for the weekend

Chicago is weird.

Can't wait to see it in an unlimited boat. Actually, can't wait to see it in all the H boats.

Future Olympian?

We are going to die at their hands.

^^ This.

Between this and AI inroads, we are basically watch the birth of Skynet.

where do we draw the line before AI becomes smarter than us?

We don't. We accept their existence and we embrace it knowing that they will help us achieve immortality.
Since we live in this completely fucked up time in human civilization...I am coming out in this statement.
I now identify as a Cyberdyne Systems Model 101.

We actually live in the healthiest time in human history. People live longer and have a lower infant mortality rate than ever. There are less people being killed in wars percentage wise than ever before.

But, there are more people currently enslaved worldwide than ever in human history, which is a definite wet blanket.

Y'all need to watch Chappie or Planet of the Apes to see what happens when we invent something smarter than us.

If we accept the definition of "enslaved" to mean "trapped in virtually sub-human work environments by reason of chance," then yes, I find it intuitively obvious that these two concepts are not only mutually inclusive, but symbiotic.

Humanity, as a whole, has never* had it better in terms of prosperity, liberty, leisure time, lifespan, etc.

By definition, there must always be someone at the very bottom of the totem pole. And as he pole rises higher, the width of its base must increase. Basic materials science there.

What is your idea of a sub-human work environment? This is what I was referring to http://www.deliverfund.org/ and http://ourrescue.org/

A partial list of examples:

• Being forced to work as a prostitute.
  
• Being forced to be eaten by a bear as a form of public entertainment.
  
• Chief legal counsel to Internet Brands™.
  
• Being forced to work in an environment containing toxic chemicals, caustic materials, or imminent risk of immolation / mutilation / exposure to spallation elements, etc.
  
• Anything involving the belief that you deserve (x) amount of compensation, despite the fact that the market has determined that the value of your labor is (x/y), and being of a mindset which sees no alternative to continuing upon this path as a means of primary sustinance.
  
• Being one of those kids who lives in a little town in eastern China where the loads of electronic waste that was listed as "recycled" from the US or Europe gets dumped, and you wade through loads of transformer oil and beryllium to find the little bits of copper and iron worth saving, and then burn the rest.
  
• K-Mart (I speak to this as a former employee from my college days.)

that 3rd one is the real bad one

Egay or Ebay?

Went over to the beach this morning.

Then had lunch with some fish. I ate their friends while they watched.

What happened to the rapper on the left?
I laughed so hard.
Looks like forgot to take his meds before going the free style rap battle or maybe he suffered a stroke from smoking super concentrated crack.

Engineers. Why do you use 8/16" instead of 1/2"? Explain the reasoning for this.

https://cimg8.ibsrv.net/gimg/www.mia...f2452866c.jpeg

Because mixing denominators in fractions makes math hard. This is why I despise the way that SAE wrenches are labeled, and find the metric measurements much easier.

Like, "I need one size larger than 7/16, so that's obviously 8/16."


I'd never noticed this little guy before. He's perched over the entrance to the restroom at the back of my barber shop:

You mean mixing denominators like this?
https://cimg8.ibsrv.net/gimg/www.mia...8f0ff62215.jpg

​​​​​​I reject your reasoning. If that were the case, why wouldn't the fractions be written out in whole numbers. Ex. 0.500"

This is the first print I've seen like this. I am not the engineer, but I will not hesitate to question.

... This engineering firm also charged our company $1200 to do dye testing. I posted about this earlier.
​​​​​​

Drawings should be with decimals. I would see fractions to be acceptable to call out a specific drill bit or tap size, but otherwise decimals for all measurements. If it is with fractions, I have not seen them like 8/16" before.

We make instruments. Have used decimal inches for at least 40 years, for everything except material thicknesses, which can be fractional or Gauge; as old methods die slowly. I welcome the shift to metric which has occurred on some of our more recent, international products. But realistically, as we rarely have dimensions that need to be feet, rather than inches, our decimal inches are as easy, or easier to use than ISO (never any confusion between mm and cm).

I agree completely.

Out of curiosity, is that drawing new? I ask because the lettering appears to have been done by hand.

Just came across my desk this morning, prints are dated the 16th of this month. It is hand written, this is just a copy of the original.

The Death of the Draftsman

Interesting article. Those at the top have been sold a bill of goods by the computer software companies: "The package will do the work, and the engineer just has to run it." Sorry, no.

Unfortunately, that is like paying the CEO to wash his own windows and empty the trash. It just doesn't work that way.
True engineering talent is wasted, no one is brought up through the ranks, and most engineers are simply paper pushers.

And you end up getting shit like this:

https://cimg9.ibsrv.net/gimg/www.mia...bd5db250d5.jpg

Yup, agreed. I'm old enough to remember the smell of ammonia from the blueprint machines and you could tell from the arrowheads who made the drawing [without looking at the title block].

In a somewhat related vein, this recent announcement from GE has an enormous future effect on manufacturing.

GE Additive Chief Explains How 3D Printing Will Upend Manufacturing

Obligatory pic. 1ST additive mfg part cleared for flight by the FAA:

One particular paragraph:

The vast majority of those 855 prior components needed to be machined to 'fit' onto/in/with the others. The 12 remaining only needed to be 'finished'...

I think this is important. Mathmatically 1/8 is the same as 0.125, but the latter implies a whole lot more precision than the former does. If the system is being spec'd in inches, then it's a whole lot simpler to write "1/8" than it is to write "0.125 +/- 0.0625".

Of course, it'd be simpler to just do it all in mm to start with, but...

And because this is the random pics thread, here's a cool car I saw at the track a couple weeks ago:

Jesus, I thought I had worked for backwoods engineering firms..............this, this is what passed as acceptable?

L3, TWG, Ramsey............damn

Some drafters today don't even know why they do things. What I hate the most is the drawing made entirely in fine yellow lines. How the fuck am I supposed to print that?

Or when someone "helps you out" and draws everything on the same layer.

That 'death of draftsmen' was interesting read... Its funny to me because our company is trying to go model based (no more drawings) in the next 5-10 years and suppliers are already losing their minds. And I fight PLM and doc revision control for 50% of my time. I'd say 20% is actual engineering work.


Also funny- GD&T is being pushed down from sr management to improve quality and reduce cost. All its doing is driving part cost up because 90% of our suppliers (Taiwan) hate it and don't understand it. We get the same parts regardless.

Short Solidworks blog entry on the subject you may have read: Comparing Drawing-based and Model-based Workflows

Doesn't this kind of go with the above? All the geometric and tolerancing data needs to be in an annotated model for it to actually help manufacturing.

EDIT: Article arguing against MBD: The Argument Against Model-Based Definition

Obligatory pic:

Yeah- the GD&T thing is just a waste of everyone's time on drawings (especially for our simple parts). No one actually understands it and the supplier charges MORE even though the tolerances are actually wider because the drawing is hard to understand.

I liked our old style drawings- we could have *dimensions that notified the supplier to try hard on this feature/tolerance/surface finish. Actually worked really well.

Where did my post go?

I was typing out all the fun shit I did in my 30 years of drafting and about to paste a picture of the first drafting machine I used and the post vanished. I blame IB.

Anyway, it was in high school and was a Vemco V-Track kinda like this:

Dark wood grain and everything. SO COOOOL on a giant tilty table.


https://cimg5.ibsrv.net/gimg/www.mia...73db540628.png

My experience has been that GTD can better define requirements many times. However, it is still true that they typically have to be explained.

We use 3D models accompanied by 2D prints with minimal dimensions, typically those that need tight controls.

When you have a good supplier, he can take 3D models and turn them into parts / molds / tools in short order. If you both understand the capabilities of the manufacturing system, then it is easy to get what you expect. (wire EDM for instance).

The treatment of engineers as if we are a typing pool will not end well. We are individuals with unique backgrounds and skills. Software will not change that.

https://cimg4.ibsrv.net/gimg/www.mia...d21c72c53d.jpg

What is the GD&T thing? Thankfully I got out of the mechanical biz 1 year ago.

Ohhh, Mister high & mighty. I started out on a table with a parallel straight edge and triangles. Only the senior designers got the fancy machines.

https://cimg2.ibsrv.net/gimg/www.mia...2f1590ba2e.jpg

Geometric Dimensioning and Tolerancing. Symbols and numbers designed to make engineering drawings universal. Somewhat confusing to old timers in the shop.

Here, the old timers know GD&T but the new guys don't.

I did a couple semesters of drafting in high school with one of those 'L' ruler tables. Always got points taken off for bad handwriting. haha


I agree- GDT is a great tool if you have parts that need it and suppliers that understand it. It is not well understood in Taiwan by our suppliers- causing problems and our senior management is unwilling to go backwards.

I think we are headed in the direction of sending a 3d model and a few tolerances called out on a print that need special attention. The current transition state is frustrating.
