The answer to this depends on the respective grade of Gray Iron and Ductile. The most common grade of Gray is Cl 30 and the most common grade of Ductile is 65-45-12.
Machinery's Handbook (25thEd) list cutting speeds for these as follows for the respective cutter type:
Gray BHN 190-220; HSS 80...
The type of work instruction and what to include in work instructions is mainly what will work with the complexity of your process.
2 types I can think of are:
1) Detailed - the more complex tasks could take the form of a page or 2 or more of specific details required to be consistent with the...
Mike,
You are correct - "You may elect to make a faster, cheaper, and much uglier, crush bend, in which case your cross section changes to something between an E and an H."
The walls perpendicular to the bend change shape and are concave parabolas

Is there any way to predict the thinning of walls and length of strain along thin wall tubing specifically aluminum bent on a radius? I'm trying to get shear calculations at points along the bend but would like to account for the reduction of area.
.06" wall w/.125" corner radii - 1"sq outside...
Bob,
Have you gotten any information on your request? I just saw this. I'll be glad to check my resources when I get into work if you still would like information.

Prototypes can be a viable option prior to releasing for production. Size, complexity, and material are all factors in determining cost.
A couple of options are:
1) Smaller scale model of part you want
2) Aluminum or plastic material for prototype

I believe ASME if you are designing to that standard has details as to what is acceptable based on application and required design FS.
Great site Deanc. Arunmrao you are telling on your age now. There is still hope. One large university Virginia Tech is working on constructing a foundry for...
is the product form small enough to consider oven brazing?
it's fairly economical and there are heat treaters that do this provided the size is within their work envelope

I have a project requiring a large blank appr 30" dia to be deep drawn hydroformed. The blank is not round and will be drawn to a depth of about 5".
My searches have yielded few sources for this process.
