The DELEM DA-66S Manual Mode provides users with the flexibility to perform precise bending operations independently from automatic settings. With Manual Mode, operators can gain full control over the bending process, customizing parameters for each job. This mode is ideal for applications requiring specific adjustments that automated settings may not accommodate.

In this article, we’ll delve into the core functionalities of the DELEM DA-66S Manual Mode, providing you with a comprehensive guide to enhance your machine’s performance and output.

Manual Mode Overview

En el modo manual, se programan los parámetros para un plegado. Este modo es útil para pruebas, calibración y plegados individuales.

El modo manual es independiente del modo automático y se puede programar independientemente de los programas en la memoria.

In the top of the Manual mode screen you can find the Y-axis and the main X-axis current position. All other axes and functions are listed one by one in the two columns below. When these Y-axis value and X-axis value are highlighted it means that the reference markers of these axes have been found and that they are positioned correctly referred to their programmed values.

Above the axes and functions, large icons (tiles) with related values are showing the most used ones. These tiles can be selected and the values can directly be modified.

A continuación se muestra una lista de los parámetros disponibles en el modo manual.

Parámetros de curvatura

Método

Seleccione el método de plegado necesario. El control admite los siguientes métodos estándar:

• Air bend

• Bottoming

• Hemming

• Hemming & bottoming

The bend methods have been explained in more detail in the Program mode.

Método de desvío

Dynamic: The crowning will be controlled automatically in real-time during the bending, applying the proper corrections when needed.

Non-dynamic: The crowning will behave as a standard hydraulic crowning; there won’t be real-time corrections.

Longitud de curvatura

Program the bending length of the sheet.

Posición del producto

El valor de la posición absoluta del producto en la dirección Z. El lado izquierdo de la máquina es la posición de referencia cero.

Ángulo

Angle to bend.

Corr.α 1, Corr.α 2

Correction on angle to bend.

The angle correction should be entered as following examples indicate:

Programmed value of 90 degrees. Measured value of 92 degrees. Then it is required to program Corr.α with -2.

Programmed value of 90 degrees. Measured value of 88 degrees. Then it is required to program Corr.α with +2.

Apertura del dobladillo

The hem bend can be made with a certain opening distance between the 2 flanges. The hem opening value will be used calculating the beam position in the hemming process.

By default this parameter has the value of the Settings mode parameter Default Hem Opening.

Dobladillo rápido

When fast hemming has been enabled, the Y-axis will move at high speed down as soon as it is below the top of the die, until the hemming load opening has been reached. This will reduce the cycle time, especially in case of hemming with a U-die.

Only available when enabled by the machine manufacturer.

Corr.Y

Correction on the Y-axis position, in case bottoming has been selected.

Eje Y

The programmed or calculated Y-axis value to realize a certain angle.

Silenciar

Sequence point where the Y-axis is switched from fast closing speed to pressing speed. It is programmed here as a Y-axis position value. The programmed value is the Y-axis point above the sheet.

Paralelo

Difference of the left- and right hand side cylinder (Y1 and Y2). When positive, the right hand side is lower. When negative, the right hand side is higher. The programmed value is active below the clamping point.

Apertura

This parameter results in a certain gap opening between the punch and the die after the bend. A positive value is the gap opening above Mute, a negative value below Mute.

When you want to limit the handling time for the product you can program a small positive or a negative value.

Fuerza

Fuerza

La fuerza programada aplicada durante el prensado.

Tiempo de permanencia

Hold time of punch at the bending point.

Descompresión

Decompression distance after the bending to release the working pressure from the system. The decompression distance can optionally be set to a specific point in the cycle. Standard the decompression distance is computed, the value which is minimal required. Optionally one can chose for Mute, the calculated mute point, or Clamp, the calculated clamping point. Both options have a longer distance than the calculated one.

Velocidad

Velocidad

Pressing speed, the speed of the Y-axis during bending.

Velocidad de descomposición

La velocidad de descompresión es la velocidad programable del haz durante la distancia de descompresión.

Funciones

Esperar la retractación

In case of a retract, let the Y-axis wait until the retract is finished, yes or no.

No: the retract is started when the Y-axis passes the clamping point, the Y-axis does not stop.

Yes: when the Y-axis reaches the clamping point, the Y-axis is stopped and the retract is started. When the retract is completed, the Y-axis moves on.

Propiedades del producto

La posición del dedo (contacto), correspondiente a la posición del eje X y la posición de apoyo.

Ejes auxiliares

Eje auxiliar

If you have one or more auxiliary axes (for instance an X-axis, R-axis or Z-axis) the parameters of these axes appear here. When you have a R1-axis and a R2- axis the programmed R1-axis value is automatically copied to the R2-axis value. The R2-axis value can, if necessary, be changed afterwards.

Retraer

The retract distance of the axis during the bend. The ‘backgauge retract’ is started at the pinching point.

Velocidad

Speed of the axis in the current bend. Speed can be programmed in a percentage of the maximum possible speed.

Soporte de piezas

Eje PST

With this parameter the part support can be switched on or off. When it is switched off, the part support will stay at its zero position during the bend.

Posición R

The height of the part support before and after the bend. By default, the height will be set at the top of the die (R-position = 0.00 mm). Only available when enabled by the machine manufacturer.

Método
In DELEM DA-66S Manual Mode, you can control how and when the part support returns to its zero position after completing a bend. Options include setting the part support to return when the Y-axis reaches UDP (‘Return at UDP’) or initiating the return as soon as the Y-axis begins opening (‘Return when opening’).

Alternatively, you can use the ‘Product tilt’option to introduce an extra tilt, preventing collision between the product and the punch during Y-axis opening. The ‘Static angle support’ setting allows the part support to hold at a fixed angle, converting it into a stable support table rather than following the product’s movements. Each option offers unique advantages for optimizing machine operations within the DELEM DA-66S Manual Mode.

Ángulo de inclinación

The tilt angle determines how much the part support will move. At the machine’s front side, the support moves to a higher position (larger angle), while at the back, it moves to a lower position (smaller angle). This feature is applicable when using the ‘Product tilt’ method.

Velocidad de inclinación

This specifies the speed at which the part moves to the tilt angle, expressed as a percentage of the maximum operation speed. It is relevant only when ‘Product tilt’ is selected within the DELEM DA-66S Manual Mode.

Espacio libre de inclinación

If the decompression distance is insufficient for tilt movement, an additional ‘Tilt clearance’ can be programmed. This extra distance is included in the programmed decompression distance, ensuring smooth operation. The clearance setting is used exclusively with the ‘Product tilt’ method in the DELEM DA-66S Manual Mode.

Ángulo

The static angle to which the part support will move before the bend. Only available when method ‘Static angle support” has been selected.

Velocidad

The speed, as a percentage of the maximum speed, with which the part support moves to the static angle. Only available when method ‘Static angle support’ has been selected.

Velocidad de retorno

Return speed of the part support after a bend. The speed value is programmed as a percentage of the maximum speed.

Ángulo de parada de seguridad

The angle at which the support will stop during the return movement; the control will switch to stop. An extra start action at the control makes the part support return to its zero position.

Initial angle

The initial angle (typically the pre-bend angle of a two-stage bend) to which the part support will be moved at step change. The part support will follow as soon as the angle of the product passes the initial angle of the part support. Only valid for part support axes in front of the machine.

Initial angle speed

The speed to move the part support to the initial angle. Only valid for part support axes in front of the machine.

Corrección

Correction on the part support axes in the DELEM DA-66S Manual Mode is gradually applied during the bending process, starting at the pinching point. By the final bend position, the correction adjusts to match the programmed value. These parameters in the DELEM DA-66S Manual Mode can be easily programmed and modified as needed. Once you press the Start button, the programmed settings become active.

The parameters in DELEM DA-66S Manual Mode can be programmed and adjusted as needed. Once you press the Start button, the configured settings become active.

Tool setup

The tool setup in DELEM DA-66S Manual Mode closely parallels its setup in Automatic Mode. Although each mode allows for distinct configurations, you can opt to use the Automatic Mode’s tool setup in Manual Mode, but exercise caution with differing configurations.

In the DELEM DA-66S Manual Mode tool setup menu, you can easily add, remove, or reposition tools such as punches, dies, and adapters. This process mirrors the main Tool Setup functions, enabling custom adjustments to enhance your bending operations. Additionally, segmentation is possible when adding tools, depending on your specific requirements.

Cambiar producto

In the DELEM DA-66S Manual Mode, shifting the product’s position is streamlined using the ‘Shift Product’ function. Snapping points assist users in accurately moving the product, making it easy to align to the side of the tools or the middle of the station.

Key Functions for Product Positioning:

• Saltar a la izquierda: Shift the product to a different tool set combination on the left.
• Saltar a la derecha: Shift the product to a different tool set combination on the right.
• Desplazamiento a la izquierda: Move the product 1 millimeter to the left within the same tool set.
• Desplazamiento a la derecha: Move the product 1 millimeter to the right within the same tool set.

Utilizing these functions in the DELEM DA-66S Manual Mode ensures precise control over product positioning, enhancing both flexibility and accuracy in operations.

Parámetros de programación y vistas

In DELEM DA-66S Manual Mode, you can program parameters individually, with each shown alongside symbols and background colors for easy identification.

An information symbol indicates a change due to a recent input, highlighting adjustments made.

A star symbol alerts you when a parameter value differs from the control’s calculations, useful for deliberate or constraint-limited settings.

Errors are flagged with an error symbol if a value is incompatible with the current program, such as a hemming bend set without appropriate tools.

The right side of the screen provides access to multiple views, including Main, Macro, Manual Positioning, Corrections, and Diagnostics, enhancing user control and monitoring capabilities in the DELEM DA-66S Manual Mode.

Macro

In DELEM DA-66S Manual Mode, the Macro view displays large axis values on the screen, making it easier to read them from a distance. This feature is particularly useful when working remotely from the control panel.

Executing A Safe and Efficient Bending Operation

Manual Axis Movement Procedures

To manually move axes safely, use the DELEM DA-66S’s hand wheel. Ensure the machine is stopped when repositioning auxiliary axes, while the Y-axis requires the system to be active with specific conditions met, such as the ‘adjust’ function being active.

After tapping Manual positioning in the main screen of Manual Mode, the following screen appears:

In the DELEM DA-66S Manual Mode, you can manually move axes using the hand wheel. The steps vary depending on the axis type you’re adjusting.

Para auxiliary axes, ensure the machine is stopped (Stop button LED lit). Select the backgauge axis you wish to move, and use the wheel to reposition it.

With the Eje Y, manual positioning is similar but requires that the machine is started (Start button LED on). Additionally, the ‘adjust’ function must be activated (check for messages in the top-right if it’s not). Make sure the Y-axis is below the mute-point and that a pressing command is entered into the CNC.

By following these procedures in DELEM DA-66S Manual Mode, you can safely and effectively manage machine axes.

Teach Mode Utilization

To efficiently teach the DELEM DA-66S Manual Mode control a position discovered by manually adjusting an axis, follow this straightforward procedure. Use the hand wheel to move an axis to your desired position. To save this position, tap the axis name in the Programmed column; the actual axis value from the left will then populate the programmed axis field on the right.

Upon returning to the standard screen of DELEM DA-66S Manual Mode, you’ll find the axis parameter updated with this newly taught value.

Monitoring and Diagnostics for Safe Operations

Correcciones

In the DELEM DA-66S Manual Mode, you can view and verify corrections for the bends as a single line, similar to how it’s done in Automatic Mode. These corrections and entries in the correction database are crucial for accurate bend results. Access to the database allows you to modify and optimize these corrections, which can also assist in test bending processes.

El Tolerancia de curvatura function in DELEM DA-66S Manual Mode enables users to input entries into the bend allowance table. By adding only the necessary bend allowance corrections based on active bend parameters, you can calculate the bend allowance from the difference between programmed and measured values. To activate this feature, switch to the Settings mode.

Diagnostics and Real-Time Monitoring

In DELEM DA-66S Manual Mode, the Diagnostics feature provides a comprehensive view of the machine’s axes states. This functionality allows operators to monitor the real-time status of each axis during a bending cycle. Accessing Diagnostics ensures you can observe how the controls behave, promoting efficient and safe operations.

Monitoreo del estado de E/S

The DELEM DA-66S Manual Mode includes a detailed IO status feature, offering insights into the current state of all inputs and outputs. This real-time monitoring is crucial for assessing machine performance and swiftly addressing any potential issues during operations.

Zoomed IO View

For enhanced observation, the Zoomed IO function in DELEM DA-66S Manual Mode allows you to select up to eight pins for an enlarged view. This capability facilitates distant monitoring, ensuring you can track critical inputs and outputs with ease.

Test Bend Mode for Precision

The DELEM DA-66S Manual Mode includes a Test Bend feature designed to fine-tune your bending operations.

Once activated, the axes remain in their retract positions after the initial bend cycle, with the part support maintaining its angle if enabled. This mode halts any step changes.

Upon completing the Test Bend, the Y-axis stops at UDP, allowing operators to measure angles accurately and apply necessary corrections. After adjustments, the bend can be re-executed. The part support resumes following the Y-axis when it returns to its original position. This ensures precise corrections and improved bending accuracy.
