AutoCAD Inventor :: Sheet Metal - Automatize Bend Radius Value

Dec 31, 2013

I have a large number of parts that are set with a "2mm" Bend Radius.

1. I wish to change it to "1.5mm" but manually takes time . Ways to automatize this?
2. What Bend Radius is recommended to be used for steel sheets (1.5 ; 2; 4; 5 mm).

AutoCAD Inventor :: Changing Sheet Metal Thickness And Bend Radius

Mar 13, 2012

I wrote an app some time ago that swaps out user parameters that drive sheet metal thickness and bend radius.

it appears to work about 60% of the time when it doesn't it does not give any warning but even though the FX table shows the new user parameters driving thickness and bend radius the "sheet metal defaults dialog" thickness input box is grayed out and shows no value what so ever.  Clicking the Edit Sheet metal rule to display the "Style and Standard Edtior" the Thickness and Bendradius still show the Old userparameters.  See attached Pic.

I am setting the parameters as follows.

Replaced "Chan_Th" with "chn_thk"  in FX Userparameters



oSheetMetalCompDef.UseSheetMetalStyleMaterial = True       oSheetMetalCompDef.ActiveSheetMetalStyle.Thickness = sThick


As you can see FX reports the change but sheet metal settings does not.

This code appears to work or not at random.

AutoCAD Inventor :: Sheet Metal - Cut Across Bend

Dec 20, 2012

I have a sheet metal door with a little bracket that gets welded to the inside lip through a cut-out in the face of the door. (see assembly)

I can't get the cut-out to line up flush with the inside lip of the door, as that is where the brackets gets welded to. the current aseembly is set-up the way I want, but I can't get a flat pattern on the door, becasue of the cut going across the bend.

I have checked off the "cut across bend" in the cut dialogue box, but this leaves a small (~1/32) lip in the cut-out and runs interference in the placement of the bracket.

AutoCAD Inventor :: Sheet Metal Bend Relief?

Apr 16, 2013

Ive imported a CATIA part and I'm trying to redraw it in Inventor. I have the main panels and bend rads in but I cannot for the life of me work out how to model the bend reliefs so they are similar to the ones on CATIA. The purpose of all of this is too reduce the bend reliefs that CATIA has produced even further.

Ive added both the original dumb solid from catia and the new inventor model to an assembly and contrained them in line so hopefully you see what I mean.

AutoCAD Inventor :: Sheet Metal - Fold (bend And Twist)

Apr 23, 2012

I have the following sheet metal application: A flat bar steel (strip) 40x1mm is bent and twisted around three cylinders. In our process, the strip is running in loop around these cylinders, like a conveyor-belt. At first, it is bent around the first cylinder (blue). Then, it is bent and twisted around the second cylinder (green). Between these cylinders, a flat part is modelled so that the strip will be bent upwards (twisted) around the next cylinder. The same is done between cylinder two and three.  In praxis, when I bend the strip, no flat part will be present, because the strip is quite stiff, as it is spring steel. In my Inventor model, no stiffness of the strip is taken into consideration.

I am looking for a better way to model this strip, where stiffness of the material is taken into consideration.

AutoCAD Inventor :: Bending Sheet Metal Having Big Radius

Dec 3, 2013

We have an issue where we are trying to bend a 1mm sheet with a 24mm radius. The one side must come out 105mm wide and the flange must be 50 mm wide. inventor gives a flat pattern width of 143.4

If we bend using a brake press and a 24mm tube blade then it wont come out the right size. its like the flat pattern isn't big enough. we get the 50 mm flange but whats left over is 99 and not 105. How do we deal with something like this?

AutoCAD Inventor :: Sheet Metal - Create Flanges On A Radius

Feb 18, 2013

The question is if I have designed a part in sheet metal with multiple flanges and one of my edges follow a specific radius. Is is possible to use contour roll or any other means to create a flange on that edge that will allow me to flatten that out. I cant see it being physically possible putting a bend in there as the material would need to stretch and the bend tool would need to follow that radius.

AutoCAD Inventor :: How To Change Radius On A Bend

Oct 21, 2011

I have been trying to bend a larger radius on a corner bend but i can not seem to be able to . I start out with a face of 46" x 82"  i want to put a 1/2" bend up then a 1/2" bend out to make a z shape i'm using as a material .109 stainless steel and i want to end up with a 1/2" on the inside corners so that when i'm done i can flatten it out to get the proper sheer size for the piece the metal brake i'm using has a 1/2" die in thats why i trying to figure this out is their any way to put this kind of radius on the sheet metal bends.

AutoCAD Inventor :: Any Way To Preload Info - Bend Radius

Feb 27, 2012

Is there a way to preload information into Inventor in regards to the break press such as the dies being used or the ones available so the when the computer is deciding a bending radius,it know what tool we have?  

Currently the bend radius is set to "radius", which i am assuming is default, but I can't figure out how to change that either, and depending on the thickness it will change, but like today it said I would need a 1/16th inch radius, but we don't have a 1/16th inch die,it is an 85 degree air bending setup,and has a 4 way die with smaller and bigger openings.

AutoCAD Inventor :: Sheet Metal From Flat Sheet To Rolled Part?

A collegue asked me about this as he has been given a part to model and the details are for the flat sheet not the finished model. Is this possible in 'sheet metal'? I had a quick play but couldn't work it out. Im used to creating the finished part and 'un-folding' to get the flat pattern.Detail supplied below.

AutoCAD Inventor :: Bend Table Error / Angle Or Radius Are Outside Table Boundaries

Mar 15, 2012

The angle or radius are outside the table boundaries.  I have used bend tables before and have not run into this.  See screenshot.  What I don't understand is that in the error dialog box the Thickness is correct the Radii are correct and the Angle is correct except it is showing a -90 degrees.  Is that the problem?  The negetive?  Why is it showing a negative number.  I can't change the way the part is formed.  The problem seems to be with the lower left hand curl.  It does go ahead and flatten it, but I don't trust the results when I have the three errors.

AutoCAD Inventor :: How To Model ACM Sheet Metal

Oct 20, 2011

Very thin gauge aluminum sheets with a composite sandwiched between them.

The challenge is, the panels are relatively thick, 3mm or 4mm, but a router is used on the fold lines before bending to cut through all but the outer aluminum.  This makes for a very tight bend radius.

So, thick 3 layer material, tight bend with mitered corners.  Can Inventor's sheet metal tools handle this?
