How do I change the default bend radius in Solidworks?

How does solidworks calculate bend radius?

s = material thickness. r = bend radius. k-factor = k-factor (you can use an equation or a value) ß = aperture angle.



Bend Calculation Examples.

Angular Range Example
90 < ß <= 165 Tangent length = No
165 < ß <= 180 Tangent length = No

What should my bend radius be?

We recommend a minimum bend radius of 1t for all sheet metal parts. Thus the smallest radius of any bend in a sheet should be at least equal to the thickness of the sheet. For example, if the thickness of the sheet is 1 mm, the minimum bend radius should be 1 mm.

How do you edit a table bend in Solidworks?

You can edit a bend table in a separate Excel window. Click Edit > Bend Table > Edit Table in New Window. After editing the table, save the table, then re-insert it into the part for the changes to take effect.

How do I change the radius in SOLIDWORKS?

To change the placement of circular dimensions:

  1. Right-click the dimension.
  2. In the Dimension PropertyManager, select the Leaders tab.
  3. Under Witness/Leader Display, select a placement option. For example: Radius. Diameter. You can also right click the dimension and select Display Options.

What is the difference between bend allowance and bend deduction?

Bend Allowance and Bend Deduction Value



By definition, the bend allowance is the arc length of the bend as measured along the neutral axis of the material. By definition, the bend deduction is the difference between the bend allowance and twice the outside setback.

How do you calculate bend length?

Bend allowance calculations are used to determine the developed length of flat sheet metal required to make a bend with a specific radius and angle.



L = (Π/2 x R + Y factor x T) Θ/90
Where: L = Developed length
T = Material thickness
Θ = Bend angle in degrees (°)

What is bend allowance in Solidworks?

By definition, the bend allowance is the arc length of the bend as measured along the neutral axis of the material. By definition, the bend deduction is the difference between the bend allowance and twice the outside setback.

How do you find the minimum bend radius?

1. The minimum bending radius for cables with non-shielded conductors is seven times the armor overall diameter. 2. The minimum bending radius for cables with shielded conductors is twelve times the diameter of one phase conductor or seven times the overall diameter, whichever is greater.

How do you define bend radius?

A bend radius refers to the bend in a cable. Bend radius specifications are a measure of the tolerance of the wire or fibre cabling. The minimum bend radius refers to the lowest radius at which a cable can be bent. So a smaller bend radius means a cable is more flexible.

What is the minimum bending length?

For bends, the minimum distance between the inside edge of the bend and the outside of the hem should be 5 times material thickness plus bend radius plus hem radius.

What is a bend table?

A bend table specifies the bend allowance for a specified material thickness at specific radii, and bend angles for the flat pattern analyzer. If a specific bend angle or bend radius is not in the table, the flat pattern analyzer interpolates between adjacent cells to determine a value.

What is K factor SOLIDWORKS?

K-Factor is a ratio that represents the location of the neutral sheet with respect to the thickness of the sheet metal part. When you select K-Factor as the bend allowance, you can specify a K-Factor bend table. The SOLIDWORKS application also comes with a K-Factor bend table in Microsoft Excel format.

How is bend deduction calculated?

Here’s the formula: Bend deduction = (2 × Outside setback) – Bend allowance. With the bend deduction in hand, you can determine the appropriate flat blank size, and program the press brake so that the backgauge fingers accommodate for material elongation during each bend.
