Sheetmetal Fabrication
(OP)
Hi,
I'm working on cost-reduction project. I like to know more on sheetmetal fabrication to analyze sequesnce of operation & to negotiate with vendors. Would any of advise me with reference meaterials, videos & slides etc.,
Thanks,
Santy

What kind of sheet metal work are you doing?
Get a copy of Product Design for Manufacture and Assembly by Boothroyd, Dewhurst and Knight. There is a section on sheet metal there. There is all sorts of other useful stuff.
As noted above, you definitely should talk to your vendors.

However, as both above say, I'd try and speak to whatever vendors you may actually end up using.

Sheetmetal assemblies can be complex, and quite precise. Do some reading on the British sten gun of WWII. Genius. And developed by people not afraid to take a chance and try something totally against the convention of the day.
You mentioned sequence of operations. This all depends on your part. There are so many operations that can be done, and it also depends on the capability and the equipment of the vendor.
RE: Sheetmetal Fabrication
Exactly, that's why you probably want to try and find out what capabilities your likely vendors have, and if they can meet your functional needs.
If you need something your obvious vendors can't give you then you either need to find another vendor or find another way of 'skinning the cat'.
For instance, I fine tuned some vent holes on a low volume enclosure to suit our preferred vendors tooling. It was a case where functional requirements could be met in several ways and I was able to find an easy/cheap one.

RE: Sheetmetal Fabrication
drawoh (Mechanical) asked you what kind of sheet metal work you are doing.
You are not really going to get a sensible answer to your questions until you get more specific,and tell us what your line of work is.
That's why most of the posters are saying talk to your vendors because right now it is the only constructive answer we can give you.

RE: Sheetmetal Fabrication
1 Engineer the product - Layout the piece you are working on to obtain the most economical cut of material - Check your inventory for something close not assigned to a project - Layout the lines of cut and Break or roll and them check it against your engineering - measure twice cut once - Take the unit to the break or roll and shape the piece - then check your engineering sketch for dimention s
and weld procedures - weld it up -
Have a good day
