1. Material name: Displayed in programming screens, limited to 25 characters and must start with a letter

2. Tensile strength: Indicates the material’s tensile resistance performance

3. E module: Specifies the material’s elastic modulus

Strain Hardening Exponent

The strain hardening exponent (denoted as n) is a critical material property that directly impacts the accuracy of bending calculations. This parameter is provided by material suppliers alongside tensile strength and the E-module. Accurate entry of the n value refines inner radius calculations, leading to precise bending depth and bend allowance values—ultimately optimizing back gauge positions and the developed length for bends.

By default, the n value is inactive (set to _.__) and can be configured between 0.01 and 1.00 (a typical value for mild steel is 0.21). Resetting the value to 0 deactivates the parameter entirely.

Calculating the Strain Hardening Exponent

The n value can be calculated in two ways, depending on whether a bend allowance table is available:

1. Without a Bend Allowance Table
Perform a test bend in Manual Mode, then select the calculate n button in the material table. The system calculates the n value based on the difference between the X-axis position and the measured side length. Calculation precision relies on accurate input of sheet thickness, tool parameters, and side length measurements.

2. With a Bend Allowance Table
The n value can be derived directly from the preconfigured table. Select the relevant material and tap calculate n to display the automatically computed result.

Material Data Management

Materials are initially listed by their unique material number (ID) and can be sorted by any property for streamlined navigation. To modify or delete a material, simply select the corresponding entry line. New materials can be added by selecting an empty line and entering the required property values.
