Like I said - THERMAL DISTORTION - AKA warpage.
You have a different definition?

Rotors are GENERALLY made of grey iron - so it IS applicable.
Anything that causes movement in metal constitutes WARPAGE

Hi Clare,
Let's stop this nonsense.

That paper clearly and obviously measured two things:
a. Lateral runout
b. Disc thickness variation

Never once did that paper mention measurement of warp (as in potato chip).

I'm OK if people suggest a paper because I love to learn, but you have to
assume I'm intelligent enough to know that just googling for the word warp
connected with temperature doesn't mean the paper shows *anything* about
warp happening with temperature.

Maybe most people here deal with people who can't comprehend what a paper
says, but I can read almost any paper (I read Physics papers all the time)
and if I want to, I can comprehend what they say.

That paper said absolutely nothing about warp (as in potato chip).

I'm not chastising you. I *appreciate* that you tried to show that the disc
can get to a temperature that is hot enough to cause warp, as I had already
provided multiple references which said that such temperatures are
impossible in street use.

It's a valid question.

If someone can provide a paper that proves that such temperatures actually
commonly happen, I'll *read* (and comprehend) that paper.

But don't throw a paper at me that says absolutely zero about warp.
(Please assume I'm intelligent enough to read & comprehend the paper.)


I am NOT chastising you.
I'm just telling the truth - which is that paper had nothing to do with
warp even though the Korean authors used the word in the paper.

They were talking about:
a. Lateral runout, and,
b. Disc thickness variation
(among other things, like heat treating effects.)
Which if you understand ANYTHING about castings, metalurgy, and
materials science, is EXACTLY what we are talking about.

Good Bye.

Clare, this is exactly why this guy has to post under a different nym every
time. you, others (and I) have given him sage advice time after time and it
always evolves to some engineering paper argument. He doesn't even
acknowledge me anymore because I don't fit in with his 'process'.

So, again, I ask the question of Arlen why do you change your nym every time
you start a new thread?
