General product properties

When working with the DELEM DA-66S product drawing, precision is paramount to ensure the final output meets design specifications. Here’s a step-by-step guide to facilitate accuracy and efficiency.

Editing an Existing Product Drawing

Creating a New Product Drawing

If you’re starting a new product drawing, select the “New Product” option in the Product Library. Upon initiating a new drawing, you will be greeted with a screen displaying the general product properties. It is critical to set these initial properties carefully as they form the foundation of your project. This includes inputting essential data such as material type, thickness, and other relevant specifications. Properly setting these parameters ensures that subsequent design stages align with your overall production goals.

By following these structured guidelines within the DELEM DA-66S system, users can efficiently edit and create product drawings with a high degree of precision. Ensuring each step is meticulously executed will translate to more accurate and reliable final products.

Product ID

A unique name to identify a product program. The maximum length is 25 characters. The product ID may contain letters and numbers as available on the keyboard.

Product description

A name or description of this program. The maximum length is 25 characters. The product description may contain letters and numbers.

If an existing product ID is entered, a warning appears that this product already exists. You are asked whether to overwrite that existing product with the new product or not. If you choose ‘yes’, the existing product is erased. If you choose ‘no’, you must enter a new ID.

Thickness

Thickness of the sheet.

Material

Selection of the material type of the sheet. The control contains 4 pre-programmed materials. See Settings to program materials. Press the required material to select it as active.

Bending length

The bend length in Z-direction of the sheet.

Dimensions

Determine the use of the outside (A) or the inside (B) dimensions in the product drawing when new sides or surfaces are added. The figure below shows the definition of both the dimensions. By default this parameter has the value of the Settings mode parameter Default Dimensions.

Radius

The product radius is recalculated after selecting the tools in the tool setup, because the chosen tooling influences the resulting radius. By default this setting is ‘use calculated’. With this parameter one can overrule and select ‘use programmed’; in that case the product radius will not be recalculated and used as programmed.

Bend allowance

For the bend allowance of this product you could select ‘use calculated’ or ‘use programmed’. With ‘use calculated’ the bend allowance will be calculated with the DELEM-66S formula or the bend allowance table. To change the active directory select ‘Save as’ and ‘Change directory’. The current product is automatically copied to the new directory.

Add Notes

When Edit Notes has been pressed, a new window appears in which you can edit the text about the current product. The possible characters are displayed on the keyboard.

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.

2D product drawing

Introduction

After entering the general product data the drawing screen appears.

Understanding Essential Product Information

In the upper information row of the DELEM DA-66S interface, you will find crucial details such as the product ID, product description, and options to select inside or outside dimensions. Familiarizing yourself with this information is the first step in ensuring that your setup corresponds accurately with your intended design specifications. This helps eliminate confusion and sets a clear path for the drawing process.

Creating the Product Profile

To create a precise product profile, you can use the intuitive ‘sketch’ mode. Simply tap with your fingers on the screen to begin shaping your design. This tactile approach allows for quick initial drafts directly on the interface. After sketching, switch to entering the real product dimensions using the keyboard. This step ensures that every aspect of your design is quantified precisely, providing a solid foundation for accurate fabrication.

Entering Bending Angles and Lengths

Precision in product drawing also means accurately defining every angle and length. Use the keyboard to directly input the angle of each bend followed by the length of each side. Confirm each entry with the Enter button. The input bar will display the properties, providing a clear overview as you progress. This methodical process guarantees that the final product matches your design criteria.

Adjusting Product and Property Data

If you need to make changes, select “Product Properties” to adjust general data such as dimensions and material details. For tweaking specific angles and lines, select “Properties” to fine-tune these aspects. This flexibility is crucial for adapting to changes during the design process or correcting any discrepancies that might arise.

The currently active element (line or angle) is highlighted. In a product drawing you can program up to a maximum of 99 bends per product (graphical programming).

When the product drawing is finished it is possible to navigate to the next step in the programming process; to determine first the Tool Setup and after the Bend Sequence.

Line properties

Introduction

When the cursor is on one of the product lines it is possible to change the properties of that

line by selecting Properties.

Projection

Inside the window with line properties, the following projection properties can be programmed:

Horizontal projection

The horizontal distance a line must measure, regardless of its angle value.

Vertical projection

The vertical distance a line must measure, regardless of its angle value.

The projection function in the DELEM DA-66S product drawing tool simplifies the process of drawing diagonal lines, eliminating the need to manually calculate precise side lengths. When you’re working on a design and need to create a diagonal line, select the existing line on your screen. Once selected, you can enter either a horizontal or vertical projection distance, depending on your design requirements, and press Enter. The DELEM DA-66S system will then automatically calculate and apply the correct line length to your selected segment, ensuring precision without the hassle of complex calculations.

It will be noted on the screen if projection is not possible.

This feature is particularly helpful in maintaining accuracy and efficiency, especially when adjusting intricate design elements for a perfect fit. By leveraging the projection function, you’ll streamline your design process while ensuring that the DELEM DA-66S product drawings are both precise and reliable.

Precision selection

When the drawing cursor is on a line segment, you can select the level of precision for this line. Enter the properties and go to the parameter Precision.

When working with the DELEM DA-66S product drawing, selecting the appropriate level of precision for your lines is crucial for achieving high-quality results. You have several options tailored to meet different needs depending on the project’s requirements.

If you’re aiming for standard results, choose the “Normal” precision level, which provides adequate accuracy for most segments.

For situations where precision is paramount, opt for the “High” precision setting. During the bend sequence computation, this choice ensures that the backgauge stop position is meticulously adjusted for maximum precision in that line interval.

Lastly, if your focus is on achieving precise tolerances within a line interval, select the “Closing dimension” precision level. This adjusts the backgauge stop position accordingly, ensuring that the resulting tolerances meet your stringent specifications.

Example:

Line interval marked with the open circle should be, if possible, directly placed between back stop and the center of the die.

By carefully choosing the right precision setting, you can ensure that your DELEM DA-66S product drawing aligns perfectly with your project needs, maintaining both accuracy and efficiency throughout the process.

Notes

Specifying line intervals with high precision and closing dimensions may result in longer production time.

The precision parameter will have priority over the “front extend ratio”, if that is set to “comply if possible”.

Insert / delete bend

Dependent on the cursor selection it is possible to insert or delete a bend.

• If the cursor is on a line segment (except for the end line of the product), it is possible to

insert a new bend. The side length will be replicated to the new bend.

• If the cursor is on a bend (angle), it is possible to delete that bend.

• If the cursor is at an end line of the product, the line can be deleted.

Bend properties

Air bend

Drawing a product graphically is simply programming the line length, angle value, next line length, etc. till the product has its required shape. The bends in the product have their standard or specific properties. The bend properties can be set by selecting the bend and selecting Properties.

Bend type

With the bend type it can be determined what kind of bending process is required.

Options are:

• Air bend as normal bend with a defined angle and preferred radius.

• Bumping as bend process to realise a large radius in different steps of air bending.

• Hem bend as bend process including the pre-bend (a standard air bend with a

sharp angle) and hemming action with help of a special hemming tool.

Angle

The angle value to bend.

Preferred Radius

The intended radius which is programmed. This radius can also be a large radius requiring large radius tools.

Computed radius

The resulting radius as computed from the control settings. Amongst others the resulting radius is depending on the used tools in the bending process.

A large radius is meant to be bent with a special radius punch with large radius. If such a punch is not available, the bumping method can be selected. The radius value may not exceed the length of any adjacent sides. For the definition of the line lengths to be programmed in the part connected to a radius bend, see figure below.

Lengths L1 and L2 must be equal or bigger than the radius R.

It is also possible to create a bend by placing the cursor on the flange end where the bend is required and select Properties. In this way the pop-up window will appear with an extra parameter to fill-out.

Bumping

If a tool with large radius is not available, the bumping method can be chosen. With this method, a large radius in a product is obtained by a series of slight bends in succession.

First you can choose the Angle Definition. The available definitions are:

• The default angle is the angle which could be programmed as standard.

• The central angle is the supplement of the default angle (i.e. 180 degrees – default angle)

To apply the bumping method, the following parameters must be programmed:

Central angle: The supplement of the angle value to bend.

Radius: The intended radius which is programmed.

Number of segments:

1. Define the Radius: Begin by deciding the radius that needs to be bent. This will be divided into various segments to facilitate the bending process.
2. Calculate Total Bends: Understand that the total number of bends required is equal to the number of segments plus one. This affects how precisely you can control the final output.
3. Select Segment Count: Choose a higher number of segments if you require a tighter tolerance and a more precise bend. Keep in mind that increasing segments means more bends and requires a smaller V-die opening.

Equal bumping-segments:

1. Default Calculation: By default, the first and last segments are half the size of the middle segments. This helps in achieving a smoother finish but can complicate die selection.
2. Enable Equal Sizes: If die selection becomes problematic due to diverse segment sizes, consider enabling the “Equal bumping-segments” option. This will make all segments equal in size, simplifying tool requirements and setup.
3. Parameter Options:
   • Disabled: The default setting where segments vary in size. It involves detailed adjustments, which can lead to issues if the V-die size is unsuitable.
   • Enabled: This uniform option recalculates all segments to be of equal size, reducing complexity in bend sequence planning.
4. Recalculation Tip: If you experience challenges with V-die sizing in disabled mode, the system will prompt you to recalculate using equal-sized segments, ensuring you maintain precision and fit.

When you must program such a bend, first program a standard angle with adjacent sides. Then put the cursor back on the angle, tap the function Properties and select Bumping as Bend Type. You will be prompted to program the radius, the number of segments and if you like to have equal bumping segments or not. After programming these parameters the radius is drawn in the product and a message will appear on the screen with information about the smallest calculated segment length. The smallest segment length has consequences for the selection of the die.

Hem bends

When creating the required profile of the product with a hem bend it is possible to first prepare a flange with a prebend angle, place the cursor on the bend and select Properties. The bend properties can be programmed in the pop-up window.

It is also possible to create a hem bend by placing the cursor on the flange end where the hem bend is required and select properties. In this way the pop-up window will appear with an extra parameter to fill-out.

Bend properties

Prebend angle

The required angle of the prebend, normally a sharp angle. The angle can be set upon the best practical value, the default value is 30 degrees.

Hem opening

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”.

Side properties

Side length

The length of the flange to hem.

Prebend, two stage bending

It can be helpful to make a normal bend in two stages, enabling a specific bend sequence, one can opt to make the bend with a prebend. The property to add a prebend to an angle in a product can be found in the properties of any bend. When programming it as such, the control will divide the bending of that particular bend in a prebend and the final bend, as two separate bend steps.

Insert temporary bend

It can be helpful or even needed for the bend process, to insert a bend which finally again is taken out, enabling a certain bend sequence without collision. With the temporary bend feature a bend can be inserted which in a later bend step is unbent again to a flat side. The property to add a prebend to an angle in a product can be used for this functionality but more specific this function is also added to the insert bend function.

When tapping insert bend, the choice can be made to insert a temporary bend. This bend, including a prebend will then be processed and taken into account for the bend sequence calculation.

Bend labels (DA-6xTe only)

In addition to the view modes of the control, in Bend Sequence, but also in Drawing and Auto-mode’s graphical visualization, the bend label view is available.

1. Understand the Bend Label Feature:
   • Bend labels are designed to give each bend line a unique identifier, using alphabetic codes. This is particularly useful when you are working with multiple bends, as it simplifies the task of tracking and managing them.
2. Access the Bend Label View:
   • Within the DELEM DA-66S control interface, navigate to the view modes. You can find this feature available in Bend Sequence, Drawing, and Auto-mode’s graphical visualization settings.
3. Activate Bend Labels:
   • To switch on the bend labels, tap the “bend label view” button within your chosen mode. Once activated, small labels will appear next to each bend line on your screen.
4. Utilize Labels for Seamless Workflow:
   • Use these labels to keep track of each bend’s sequence as you manipulate the bend order during drawing or production. The alphabetical identifiers help ensure you’re aligning with your intended design layout without confusion.

Surface or bend line marker

With the marker function a specific surface or bendline can be marked improving the

recognition specific of sides and bendlines.

Functions:

Set marker

One can select and point at a specific point in the product to place the marker. A cylindrical

“label” will be placed at the point of insertion. The marker can be moved to a new position by

setting the marker on a new position. This marker will be shown in Automatic mode.

Flip marker

The top/bottom colors can be swapped if this would suit the situation better.

Remove marker

Remove the marker from the product.

Foil side indication

To increase the recognition and to prevent erroneous positioning of the unfolded product one can add a foil side to the product visualization. With functions ‘apply foil’ and ‘flip foil’ the desired side can be selected.

Functions:

Apply foil

One can apply a foil indication to the product. One side of the products color will be clearly changed indicating the foil side.

Flip foil

The top/bottom of the applied foil side can be swapped if this would suit better.

Remove foil

Remove the foil from the product.

Measurement function in graphical views

Within the graphical drawing screens the measurement function enables the measurement of developed length in various directions. By selecting opposing lines in the similar direction the resulting dimension line will be shown within the drawing.

The incorporation of the calculated bend allowance is only available after tool selection and a complete bend sequence has been carried out.
