Editing the Sheet and Tool Parameters

This section explains how to change the different sheet metal parameters needed to create your first feature.

  1. Click Sheet Metal Parameters .

    The Sheet Metal Parameters dialog box is displayed.

  2. Change the Thickness if needed.

  3. Change the Default Bend Radius if needed.

    The Default Bend Radius corresponds to the internal radius and is linked by default to the creation of the bends.
    Convention dictates that the inner angle between the two elements is used to define the bend.
    It can vary from 0deg to 180deg exclusive. This angle is constant and the bend axis is rectilinear.

  4. Click OK to validate the Sheet Metal Parameters.
 

The Standard field displays the Standard to use with the part, if implemented. The name of this standard file is defined in a Design Table.

Parameters can be defined in a Design Table. To do so, press the Sheet Standards Files... button to access the company-defined standards, if need be.
All parameters hereafter, or only some of them, can be defined in this Design Table:
   
Sheet Metal Parameters Column associated in the Design Table Definition
Standard in Sheet Metal Parameters SheetMetalStandard sheet reference name
Thickness Thickness sheet thickness
Default Bend Radius DefaultBendRadius default bend radius
K Factor KFactor neutral fiber position
Radius Table RadiusTable path to the file with all available radii
In all cases, the Thickness parameter must be defined in the Design Table in order for the other parameters to be taken into account.
Whenever both Radius Table and Default Bend Radius are defined in the Design Table, only the Radius Table will be taken into account for the bend creation.
   
Standard Names For Holes Column associated in the Design Table Definition
Clearance Hole ClearanceHoleStd path to the Clearance Hole Standard file
Index Hole IndexHoleStd path to the Index Hole Standard file
Manufacturing Hole ManufacturingHoleStd path to the Manufacturing Hole Standard file
Fastener Hole FastenerHoleStd path to the Fastener Hole Standard file
   
Standard Names For Stamps Column associated in the Design Table Definition
Flanged Hole ExtrudedHoleStd path to the Flanged Hole Standard file
Bead BeadStd path to the Bead Standard file
Circular Stamp CircularStampStd path to the Circular Stamp Standard file
Surface Stamp SurfaceStampStd path to the Surface Stamp Standard file
Flanged CutOut FlangedCutoutStd path to the Flanged CutOut Standard file
Curve Stamp CurveStampStd path to the Curve Stamp Standard file
When a parameter refers to a path, another sub-Design Table will be associated to the corresponding feature.
 

Example for a bend allowance table
  A bend table is associated to the default bend radius. Each bend radius is linked by a formula to the default bend radius.

If a bend table is defined, the bend allowance (for a given angle) is taken into account when the bend is created. Otherwise, the default K factor is used.

You should know that bend tables are used only for:

  • the default bend radius; in the case of a non-standard bend, the K factor is used by default. In this case, you will need to modify manually the local K factor if you want the required allowance to be taken into account.
  • the Bend and Bend from Flat features; other features use the K factor for flat length computation.

  Hole Standard:
Whenever a hole is created, a design table will associate its radius with a standard name.
