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 deformation is represented by the bend allowance V, defined by the formula L = A + B + V where L is the impart unfolded duration A and B the dimensioning continuances as defined on the figures below bend 90 bend 90Bend Allowance http//arbredsy/FmoCXR8/SheEnglish/sheug. doc/src/sheugbt0102. htm (1 of 3) 12/7/2001 51323 PM Another counselling to compute the sheet metal deformation is the neutral fiber commentary (K Factor) W = a * (R + k * T) where W is the flat bend width R the inner bend radius 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, th e neutral fiber represents the limit surrounded by the existent compressed area inside the bend and the extended area outside the bend. Ideally, it is represented by an arc located inside the thickness and entered on the bend axis. accordingly the K Factor always has a value between 0 and 0. 5. When you define the sheet metal parameters, a literal feature defines the default K Factor, according to the DIN standard K = (0. 65 + log(R / T) / 2) / 2 This formula can be inactivated or modified using Knowledge Advisor workbench. When a bend is created, the bend K Factor and the bend allowance literals are created. Two cases may then occur If the Sheet Metal K Factor has an activated formula and uses the default bend radius as input parameter, the same formula is activated on the bend K Factor with the bend radius 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. Th is formula is fairly complex and it is powerfully recommended not to delete it. V = a * (R + k * T) 2 * (R + T) * tan ( min(p/2,a) / 2) Though it is possible to deactivate the formula to enter a contumacious value. Finally, the bend flat width is computed from the bend allowance value. The bend allowance can be locally redefined when creating bends from walls, generating bends automatically, Bend Allowance http//arbredsy/FmoCXR8/SheEnglish/sheug. doc/src/sheugbt0102. tm (2 of 3) 12/7/2001 51323 PM Creating Walls This section explains and illustrates varied methods to create walls. constitute walls from an existing Part click the icon, and select a face of a wall pass water a wall from a sketch use the sketcher to define the profile, and set the material side.

You can also bring to create the wall with or without a bend by checking the With Bend option. 4.If there is no wall from which a limit can be computed, the reference element is the edge of the reference wall. From an Edge http//arbredsy/FmoCXR8/SheEnglish/sheug. doc/src/sheugbt0802. htm (3 of 6) 12/7/2001 51325 PM A wall on edge is defined by the selected edge (reference edge). When the reference edge is modified, by adding any feature that shortens the edge (a bend to an adjacent wall on edge or a cutout for example) the wall on edge based on this reference edge is recomputed. To avoid this you may create the bend manually on the wall modifying the edge used as the reference to create the other wall eorder the creation of walls to postpone the creation of the modifying feature both limits are computed with the same reference icon. The bend is not previewed, even if the option With Bend is checked. However it will be created. The selected options are modal and will be proposed to create the next wall. Walls on edge being contextual features, if you break the profiles continuity by inverting the material side of a wall, you may have to manually re-specify all features based upon the modified one, even if they are not directly affiliated to the modified wall, in order to update the part later onwards.This is the case when creating a wall on edge from another wall on edge, for example From an Edge http//arbredsy/FmoCXR8/SheEnglish/sheug. doc/src/sheugbt0802. htm (4 of 6) 12/7/2001 51325 PM If you invert the material side of the reference wall on which the first wall on edge has been created, both walls on edge are move (as if you were flipping the geometry) If you invert the material side of the first wall on edge (and not the material side of the reference wall), the second wall on edge is relocated. Indeed, its specification being relative to the first wall on edge, when its input data (i. e. he edge selected on the first wall on edge) is modified, the second wall on edge is rebuilt at a new location. 5. Click OK in the Wall On Edge Definition dialog box. A WallOnEdge. x element is created in the specification tree.
