To begin DELEM DA-66T product programming, it’s important to familiarize yourself with its functions and parameters. The program interface is user-friendly, designed to allow easy navigation and setup.

To edit an existing CNC program, select a product in the Products overview and select the navigation button Program. When starting a new program, select New Program and after giving in the main product properties, the system will automatically switch to Program.

To change the main product properties tap Product Properties. These parameters of the program are the same for every bending of the program (main data of program).

Start by exploring the main functions: loading the material, selecting the die, and entering necessary specifications. Each parameter, such as material thickness, length of the workpiece, and tooling setup parameters, is crucial for accurate product creation.

Parameter explanation:

• Product ID: Assign a unique identifier for each program, up to 25 characters, using letters and numbers.

• Product Description: Provide a descriptive name or number for the program, also limited to 25 characters, allowing for letters and numbers.

• Angle Selection: Choose between two Y-axis programming modes:

0 = Absolute position for a bend.

1 = α, where the angle is specified and the Y-axis position is computed.

• Thickness: Thickness of the sheet.

• Material Selection: Choose from 6 predefined or 99 programmable materials to calculate bending depths. Configure materials on the Materials page in Settings.

• Blank Length: Define the original sheet length needed for the product, calculated if based on a 2D drawing.

• Connect Programs: Link programs for creating 3D products from multiple steps.

The main screen shows the available bends and from this main screen, from every available bend, specific paremeters can be viewed and edited.

The bend selector in the top of the screen can be used to navigate thru the bends in DELEM DA-66T Product Programming. The indicated bends can be tapped to easily select the desired bend data.

Opens a new window, in which product properties, effective for all bends, are shown and can be edited.

Understanding Bend Parameters

The DELEM DA-66T includes a comprehensive list of bend parameters crucial for precise operations. The product ID and product description are displayed in the top row on the screen.

You’ll begin by selecting the correct tools, considering the material type and thickness.

• Punch Selection: In DELEM DA-66T Product Programming, the punch’s name (ID) is crucial. Tap to modify it or choose from the library for streamlined tool management.
• Die Selection: Easily tap to select or change the die from the die library.
• Punch Adapter: Select and program the punch adapter from the library. DELEM DA-66T Product Programming relies on the Machine mode settings for efficient adapter use.
• Die Adapter: Similarly, choose a die adapter via DELEM DA-66T Product Programming, contingent on Machine mode parameters for optimal operation.
• Tool Programming: Program tool IDs efficiently or browse the library for tool options. Use ‘Turn Punch’ or ‘Turn Die’ to adjust tool orientation.

Bend parameters such as bend angle, radius, and flange length are adjusted based on the desired output.

Bend parameters

Method

Select the required bending method. The control supports 5 methods:

• air bend

• bottoming

• hemming

• hemming & bottoming

• handling

The following are the detailed particulars:

The DELEM DA-66T Product Programming efficiently calculates the required Y-axis position to achieve the programmed angle by bringing the punch to the necessary depth.

In DELEM DA-66T Product Programming, the sheet is bent by pressing it between the punch and die, assuming the bottom of the die as the necessary Y-axis position for precise bending.

With DELEM DA-66T Product Programming, the sheet is folded in two after a previous sharp angle bend. The system accurately calculates the Y-axis position as the die surface plus twice the sheet thickness, using ‘hem opening’ programming for adjustments.

Similar to hemming, but DELEM DA-66T Product Programming assumes the top of the die as the Y-axis position, ensuring precise folding and pressing between punch and die.

Handling: The DELEM DA-66T Product Programming facilitates non-bending steps by keeping the Y-axis stationary, allowing backgauge axes to position as per programmed values. An external step change (C-input) is needed for product handling efficiency.

• Note 1: The hemming bends are shown here with a special hemming punch, but this is not required.

• Note 2: When bottoming operation is selected, the end of bend position of the Y-axis beam depends on the working force. If however the force is sufficient for the beam to go to the calculated Y-axis end of bend position, the beam stroke will be limited by the position value.

• Bending length: Length of the sheet between tools.
• Angle: The required angle of this bend. This parameter only appears if angle programming is selected with the parameter ‘Angle sel.’ and the bend method is an air bend.
• Hem Opening: The DELEM DA-66T Product Programming calculates the beam position for hemming bends based on the opening distance between flanges.
• Bend Position: The Y-axis position required for a bend emerges when using absolute programming or when bottoming/hemming methods are active.
• Opening: This parameter defines the gap between the punch and die post-bend. In DELEM DA-66T Product Programming, a positive value indicates a gap above ‘Mute’, and a negative value below.
• Auxiliary Axis: DELEM DA-66T Product Programming interprets negative X-axis values as relative, subtracting them from the current position, useful for chaining operations.
• Retract: The retract distance of a selected axis in the current bend within DELEM DA-66T Product Programming starts when the beam pinches the sheet, optimizing handling time.
• Axis Speeds: Speeds in DELEM DA-66T Product Programming can be set as a percentage of the maximum, ensuring precise control over production processes.By understanding and utilizing these features of DELEM DA-66T Product Programming, manufacturers can significantly enhance efficiency and productivity.

Edit notes

To attach a PDF file to the note tap Attach PDF. Via the directory browser a PDF file can be selected and will be incorporated in the product file.

When solely a PDF file is attached without a textual note, the PDF will be shown instantaneously when the user presses the Notes indicator in Auto mode.

Gauge function

Additionally, the gauge function assists in positioning the material correctly, ensuring consistent accuracy in repetitive operations.

In DELEM DA-66T Product Programming, the ‘Gauge Func’ opens a window to manage backgauge parameters, crucial for programming the desired finger positions per bend.

• Angle: Determines the angle of backgauge fingers for precise angular positioning.
• Length: Sets the product’s side length for backgauge positioning, specifically Z-positioning.
• X: Manually adjustable position of the fingers in the X-direction for sheet placement.
• R: Manually adjustable position in the R-direction, enabling finer control over positioning.
• Z: Z-direction adjustments allow for optimized finger positioning.
• Lay-on: Allows for programming multiple finger positions using DELEM DA-66T Product Programming, impacting axis positions while maintaining gauge positioning.
  • Lay-on = 0: no lay on (default)
  • Lay-on = 1: lay on first level
  • Lay-on = 2: lay on second level
  • Lay-on = 3: lay on third level
• Usage Parameter: Parking functionality within DELEM DA-66T Product Programming; parks fingers based on Z-position when not in use. Applicable when more than two fingers are present.
• Effect of Changes: Adjusting ‘Lay-on’ influences X and R axes positions while keeping gauge positions constant, simplifying the programming process within DELEM DA-66T Product Programming.

Connecting CNC programs

With DELEM DA-66T Product Programming, use the Connect parameter to create 3D products by executing bend sequences in succession. Program two directions:

1. Create and program the bend sequence for each direction.
2. Connect programs by selecting sequences through the product library and using the Connect parameter.
3. When linking more programs, each aligns with the next, looping back to the first.

To produce with connected programs:

1. Select the first program.
2. Enter Automatic mode.
3. Program the product quantity with ‘stock count.’
4. Press Start to begin the sequence.

Upon completion of the first program, the next starts automatically, indicating the remaining count.

Special Edit Remarks

In DELEM DA-66T product programming, special edit remarks are crucial for customization and specific job requirements. This feature allows operators to input additional instructions or modifications that can adapt the bending process to unique demands. It ensures that any specific detail or concern is noted and addressed, providing a personalized touch to the manufacturing process and fostering a deeper understanding of the machinery’s capabilities.

In DELEM DA-66T Product Programming, after modifying program data, the system does not auto-calculate the following:

1. Force
2. Decompression
3. Crowning Device Setting
4. Z-axis Position Offset
5. X-axis Position Correction

Here’s how the recalculation works in DELEM DA-66T Product Programming:

• Parameters 1 through 4 are automatically recalculated only if ‘Auto Computations Edit’ is enabled in the settings.
• Parameter 5 is recalculated when ‘Active Bend Allowance Table’ is activated in the settings. Corrections for the X-axis can be made using ‘Corr.X’ for individual bends and ‘G-corr.X’ for all bends in the active program.

Exceptionally, when the ‘Bend Method’ parameter is changed, the Force and Decompression adjust automatically. This highlights how DELEM DA-66T Product Programming streamlines operations for improved efficiency by managing parameter recalculation effectively.
