SHEET METAL BEND FORMULA NOT WORKING

[chetnik]

When I was using V14 for sheet metal design, I altered the PZL file in the Table folder. Existing formula is good for mild steel, but shrinkage for stainless is about half.

The old equation was PZL=ItoM((R + m_CurrentThickness * k/2) * PI *A/180))

I needed it to be half the actual amount so the equation was revised as follows:

PZL=ItoM((R + m_CurrentThickness * k/2) * PI *A/180))/2

After registering the dll file. This routine worked as planned in V14.

I have made the same changes to V15 and when I invoke the equation option "table.pzl", my flat length is increasing, not shortening. It seems as though the program is taking the pzl as twice the amount in instead of half. The whole equation is divided by 2 (/2) and this should not be happening. I even went into the ansitable folder and modified this formula and registered it too. I wanted to make sure my table folder was not corrupt.


Are there any documented problems, or does anyone have a fix?

Need help from the experts out there.

when i work w/ my stainless parts i just go into the variables and change my neutral factor from the stock .33 to .451493 for 304 s/s....all my parts are coming out as intended on the shop floor...give it a try and let me know...

HI

It's the same for me, in order to have the proper flat sheet, I adjust the neutral factor according to the thickness of materials, it take some time to have the correct results but once you got them it really helpful.

Good luck
