Click the Parameters icon . 1. The Sheet Metal Parameters dialog box is displayed. The fourth tab concerns the bend allowance. When a bend is unfolded, the sheet metal overrefinement is represented by the bend allowance V, defined by the mandate: L = A + B + V where: L is the total unfolded length A and B the dimensioning lengths as defined on the figures below: bend < 90° bend > 90°Bend Allowance http://arbredsy/FmoCXR8/SheEnglish/sheug. doc/src/sheugbt0102. htm (1 of 3) [12/7/2001 5:13:23 PM] Another way to compute the sheet metal deformation is the neutral theatrical role translation (K chemical element): W = a * (R + k * T) where: W is the flat bend width R the inner bend spoke T the sheet metal thickness a the inner bend angle in radians. If b is the opening bend angle in degrees: a = p * (180 †b) / 180 Physically, the neutral fiber represents the limit between the corporeal compressed subject area in perspective the bend and the extended area outside the bend. Ideally, it is represented by an electric arc located inner the thickness and entered on the bend axis. because the K portion al ways has a value between 0 and 0. 5. When you define the sheet metal parameters, a literal feature defines the default K portion, according to the DIN standard: K = (0. 65 + log(R / T) / 2) / 2 This conventionality seat be de mad or modified using Knowledge Advisor workbench. When a bend is created, the bend K Factor and the bend allowance literals are created. cardinal cases may then occur: If the Sheet Metal K Factor has an activated formula and uses the default bend r as input parameter, the same formula is activ ated on the bend K Factor with the bend rundle as input.Else the bend K Factor is a formula equal to the Sheet Metal K Factor. The bend allowance literal is equal to a formula representing the use of the bend K Factor. This formula is sanely complex and it is strongly recommended not to strike down it. V = a * (R + k * T) †2 * (R + T) * tan ( min(p/2,a) / 2) Though it is possible to demobilize the formula to enter a dictated value. Finally, the bend flat width is computed from the bend allowance value. The bend allowance can be locally redefined when creating caisson disease from skirts, generating flex automatically, Bend Allowance http://arbredsy/FmoCXR8/SheEnglish/sheug. doc/src/sheugbt0102. tm (2 of 3) [12/7/2001 5:13:23 PM] Creating Walls This section explains and illustrates different methods to create circumvents. render beleaguers from an brisk Part: click the icon, and select a face of a breakwater ready a surround from a insinuate: use the subject fie lder to define the profile, and set the satisfying side.

Here we select a point lying on the spine as the first selecting element, and a plane intersecting the spine as the second limiting element. 4. Make sure intersecting elements are normal to the spine, and they intersect it only once. Specify the swept wall values. In the example of the flange you set the Radius, Length and Angle values. You may also click More >> to display further options. See Creating a Flange. 5. 6. Click OK. The swept wall is created within the limits on the spine.

Editing a feature must be done in its definition view. If not, a message is automatically issued, prompting you to change views, before editing the feature. Unfolding http://arbredsy/FmoCXR8/SheEnglish/sheug. oc/src/sheugbt1200. htm [12/7/2001 5:13:30 PM] Folded/Unfolded View Access This task shows how to unfold the part. 1. Click the Unfold icon . The part is unfolded according to the reference wall plane, as shown below. 2. Click this icon again to refold the part for the next ta sk. Bend limits and stamping are now displayed in the unfolded view. When designing in context, If a CATProduct document contains several SheetMetal parts, only one part can be visualized in the unfolded view at a time. Folded/Unfolded View Access http://arbredsy/FmoCXR8/SheEnglish/sheug. doc/src/sheugbt1201. htm [12/7/2001 5:13:30 PM] Concurrent AccessThis task explains how to display the Sheet Metal part in two windows: one with the folded view, one with the unfolded view. Any modification in one window is displayed in the other window. 1. Click the Multi-view icon . The part is unfolded in a second window. 2. Choose the Window -; Tile Horizontally menu item. Both windows are tiled. Activate the window in which you want to work. Concurrent Access http://arbredsy/FmoCXR8/SheEnglish/sheug. doc/src/sheugbt1202. htm (1 of 2) [12/7/2001 5:13:30 PM] Any modification in one view is taken into account in the other view enabling the user to make modifications in the best possible context. In the multi-view mode as in the standard unfolded view, all constraints are displayed in the geometrical views. Once in the Multi-view mode, the standard icon Unfold is not continuing available. The Multi-view function is not available from a standard unfolded view. Only parts with bends can be unfolded. Cutting faces and open faces are not displayed in Multi-view mode. Concurrent Access\r\n'
