The slit is there to prevent deformation of the hole and is supposed to be welded shut afterward. I am pretty sure this is a common practice. Now I'm wondering if the slit should be closer to the hole and not right on the bend line. The fab shop is pushing to make it a 3-piece welded part. Right...
@berkshire, that was a hypothetical extreme case. I guess I'm wondering at what point the thinning becomes the cause of cracking on the outside radius. Here is the long-awaited specimen:
We have noticed that extending the slit so that there is only 1/2" width material left at each end, we get...
I'm just looking for a rule of thumb. Consider an extreme case, where the width of bend is much less than material thickness, say only 10% of thickness (0.050" wide for 1/2" plate). We would expect separation on the outer radius even if you follow the minimum inside radius rule (thickness of...
We are getting cracking on the outside radius of 3/8" thick plate bent at 90°. The bend radius is specified at 1/2" but could be as low as 3/8" if the operator doesn't check the drawing.
The width of the bend is only 1/2" in two locations with a hole feature in between. The direction of the...
To answer MintJulep and drawoh, I believe the breakdown in the ECR system is the fault of our engineering dept. Right now, the paper ECR's are not logged, and I see no evidence that my predecessor did. We are now getting complaints from the shop that former ECR's have not been dealt with, but I...
Actually, our shop deals in low enough volumes that we don't really issue ECN's other than an email to the purchasing dept. The changes just appear on the drawings for the next run. And, since our electronic drawings are always up to date, shop personnel can trust them to be current.
The...
drawoh,
My understanding is that the Google Form would exist online in an empty state and only those given access can submit an ECR. Using proper permissions, only the eng dept would be able to view the data.
MintJulep,
We use Vault Basic to publish most current dwf's to a server that can...
Has anyone thought of using Google Forms for cataloguing ECR's? Once the form is set up, anyone can access it from any location and the results are placed into a Google spreadsheet (which can be exported to excel).
I am not trying to advertise, but I have been tasked with upgrading our existing...
I discovered a solution to my error. I turned off User Account Control (in Vista) and now I can get the model to analyze. User Account Control usually prompts for permission to make any changes in Windows system files (or System32). I suspect that Algor is using the Windows System32 folder...
I forgot to mention that I am using a 64 bit machine. Also, I tried the Regall.bat and got several "Access is denied" sequences when I run it, then it errors out.
I have a similar error (shown at bottom) that I received after installing on a new quad core. The analysis worked before on the old machine, and it apparently works for my Algor rep.
I believed it must be an installation issue. I re-installed it and I still get the same error. I am an...
