Re: Sheet metal Cad

Hello Doug,

Widely used? Don't know! But I learned it FROM a member of the trade,
and it WAS "widely used" by him :-)
K factor is just the amount to be "added or subtracted" from the OAL
(OverAll Length) of the part (measured flat) so that the stretching
and shrinking which occurs (at 20 percent of the thickness. Or 80;
depends which side yer on <G>) as the part is folded will result in
proper final dimensions. It is pretty easy to add and subtract
this "factor" when laying out parts. The factor is dependant on
material type, thickness, degree and radius of bend.


Hey, I just went looking online to see if it WAS widely used. YES!
more importantly, I found this:

http://www.appliedproduction.com/PFLD_Lite.htm

It is a sheet metal layout program which appears to have a free 21
day trial! and Figures the K-factor(s) for you...

Hope this helps.

P.S. For anyone "wondering" if the price of DSL or Cable connection
to the internet is "worth it"; the type of thing I just did (open
another browser, search QUICKLY, then return to the post) certainly
is worth the relatively few dollars difference each month... It is
phenomenal how much more useful the internet becomes when you can
download at 40k/second (DSL average in my area) or up to 350k/second
(late night cable downloads. I once got 10 megs in 24 seconds!)
Changes how you use the 'net. FYI
