CybTouch 8 Materials configuration plays a critical role in achieving accurate bending results and reducing setup time. The controller uses material-specific properties such as thickness, sigma value, springback compensation, and blank length calculation parameters to generate precise bending programs. By properly configuring CybTouch 8 Materials, operators can improve angle accuracy, reduce trial-and-error adjustments, and ensure consistent production quality across different material types.

In this guide, I will explain how to access the Materials page, configure material properties, manage springback corrections, apply BDC compensation, and create custom materials for specialized applications. Whether you are working with mild steel, stainless steel, aluminum, or custom materials, understanding CybTouch 8 Materials will help you optimize bending performance and improve programming efficiency.

Accessing the CybTouch 8 Materials Page

The Materials page allows operators to define and manage the characteristics of different materials used during bending operations.

To access the Materials page:

1. Open the controller menu.
2. Select Materials.
3. Enter the required password if access protection is enabled.

Depending on the machine configuration, access to the Materials page may require a Level 2 password.

The controller includes several predefined materials by default, including:

• Steel
• Stainless Steel
• Aluminum

Additional materials can be created and customized according to production requirements.

Understanding Material Parameters

Each material stored in the CybTouch 8 database contains several configurable properties that influence bending calculations.

Material Name

The Material field identifies the selected material.

Operators can rename materials to match internal production standards and simplify material selection during programming.

Default Thickness

The Default Thickness parameter automatically populates the thickness value when creating a new part using the selected material.

Using predefined thicknesses helps:

• Reduce programming time
• Improve consistency
• Minimize data entry errors

Default Sigma

Sigma represents the tensile strength of the material and is used during force and bending calculations.

The controller uses this value to estimate:

• Required bending force
• Material behavior
• Springback characteristics

Accurate sigma values help improve calculation precision and reduce correction requirements.

Display Option

The Displayed parameter determines whether a material appears in the material selection list.

When enabled:

• The material can be selected during programming.

When disabled:

• The material remains stored but hidden from normal operator menus.

This feature is useful for keeping unused materials out of production screens.

Configuring K DIN 6935

The K DIN 6935 parameter is used during blank length calculations according to the DIN 6935 standard.

Unlike traditional K-factor calculations, this parameter adjusts the thickness value used within the DIN 6935 formula.

Proper configuration can improve:

• Flat pattern calculations
• Blank length predictions
• Material consumption accuracy

For high-precision manufacturing applications, reviewing this parameter is recommended whenever new materials are introduced.

Using Predefined Thickness Values

CybTouch 8 allows operators to define up to seven predefined thickness values for each material.

Benefits of Predefined Thicknesses

Common thicknesses can be stored for rapid selection, such as:

• 1 mm
• 2 mm
• 3 mm
• 4 mm
• 5 mm
• 6 mm
• 8 mm

Advantages include:

• Faster programming
• Consistent data entry
• Reduced operator mistakes
• Improved workflow efficiency

When creating a new program, operators can simply select a predefined thickness instead of entering values manually.

Setting Minimum and Maximum Thickness Limits

The Thickness Min/Max parameters define the acceptable thickness range for a material.

These limits help prevent invalid programming data and improve consistency.

For example:

• Minimum thickness: 0.5 mm
• Maximum thickness: 90 mm

If an entered value falls outside the permitted range, operators can quickly identify and correct the issue before production begins.

How to Configure Springback Correction

Springback compensation is one of the most valuable functions available within CybTouch 8 Materials.

Different materials react differently after bending. As pressure is released, the material partially returns toward its original shape, creating a deviation from the programmed angle.

Springback Correction Table

The controller allows three correction zones:

• Below 90°
• Between 90° and 130°
• Above 130°

Correction values can be entered for each range.

The controller automatically interpolates between these values to generate a smooth compensation curve across the entire bending range.

Example of Springback Compensation

Suppose a material exhibits approximately:

• 1° springback below 90°
• 2.5° springback between 90° and 130°
• 5° springback above 130°

The controller will automatically apply intermediate values when calculating bend positions.

This significantly reduces manual angle corrections during production.

Benefits of Springback Correction

Properly configured springback tables can:

• Improve angle accuracy
• Reduce scrap rates
• Minimize test bends
• Improve repeatability
• Increase production efficiency

For materials that consistently produce angle deviations, updating springback values is strongly recommended.

Understanding BDC Correction

BDC (Bottom Dead Center) Correction allows operators to apply a permanent adjustment to the calculated bottom position of the ram.

Why BDC Correction Is Important

Small differences between theoretical calculations and actual machine behavior can affect final bend angles.

BDC Correction compensates for these systematic differences.

Unlike temporary bend corrections, this adjustment remains active across all bending operations.

Important Considerations

BDC Correction should be used carefully.

Large correction values may indicate:

• Machine calibration issues
• Beam indexing problems
• Tooling inaccuracies
• Incorrect material data

If excessive corrections are required, further machine inspection is recommended.

How to Add a New Material

Creating custom materials allows the controller to support specialized production requirements.

Step 1: Select an Unconfigured Material

Choose an unused material slot from the material database.

Step 2: Enter Material Characteristics

Configure:

• Material name
• Sigma value
• Thickness limits
• Predefined thicknesses
• Springback compensation values

Step 3: Save the Material

After all parameters have been entered, save the configuration.

The new material will immediately become available for future programming operations.

Best Practices for CybTouch 8 Materials

To achieve the highest bending accuracy, material data should be reviewed and updated regularly. Whenever a new material supplier, thickness, or alloy is introduced, test bends should be performed and springback values verified.

Maintaining an accurate material database helps reduce setup time, improve consistency, and maximize the performance of the CybTouch 8 controller. By properly configuring CybTouch 8 Materials, operators can create more reliable programs, improve production quality, and achieve more predictable bending results.
