Whether you’re an experienced operator or new to the technology, I’ll explain the implementation process, ensuring you can leverage these insights to optimize your workflow and improve your product outcomes.

Let’s dive in and explore the intricacies of DELEM DA-66T Product Drawing.

General Product Properties

The DELEM DA-66T comes with a set of clearly defined product properties to streamline your operational workflow.

To start a new product drawing, choose New Product in the product library.

When a new product drawing is started a screen with general product properties appears. First these properties, general data, should be set before starting with the product drawing.

The Product ID provides a unique identifier that distinguishes each item in the system. The maximum length is 25 characters.

Accompanied by a Product Description, it offers a detailed overview to help you accurately identify and manage your models. The maximum length is 25 characters. 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.

The product radius is recalculated after selecting tools in the tool setup, as the chosen tools affect the final radius. By default, the setting is ‘use calculated’. However, you can choose ‘use programmed’ to prevent recalculation and use the programmed radius instead.

To change the active directory select Change Directory. The current product is automatically copied to the new directory.

You can conveniently append additional information through the Add Notes feature, allowing for personalized tracking and specifications that tailor operations to particular needs.

When Edit Notes has been pressed, a new window appears in which you can edit the text about the current product.

To attach a PDF to a note, tap ‘Attach PDF’ and select the file through the directory browser to include it in the product file. If only a PDF is attached without text, it will automatically display when the Notes indicator is pressed in Auto mode.

2D Product Drawing

Creating a 2D product drawing with the DELEM DA-66T is streamlined for precision and efficiency.

In the DELEM DA-66T Product Drawing process, after entering general product information, the drawing screen appears displaying details like product ID, description, dimension settings, and directory.

You can create the product profile in ‘sketch’ mode by tapping with your fingers and refining dimensions using the keyboard. Angles and lengths can be input directly with the keyboard to define the bends and sides.

Product details and element properties can be modified through Product Properties and Properties respectively, with the active element highlighted.

The system allows programming up to 99 bends per product in the DELEM DA-66T Product Drawing.

Once the drawing is complete, you can proceed to set up tools and determine the bend sequence.

Line Properties

When the cursor is on one of the product lines it is possible to change the properties of that line by selecting Properties.

Precision is fundamental in any engineering process, and the DELEM DA-66T provides comprehensive Line Properties to aid this.

With Projection options, you can render drawings that accurately reflect necessary dimensions and alignment.

• 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 Precision Selection feature ensures that every element of your drawing adheres closely to the required tolerances, safeguarding the quality and uniformity of your products.

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.

Precision:

• Normal: Achieve normal accuracy for this segment.

• High: At bend sequence computation the back gauge stop position will be chosen to get the highest possible precision for this line interval.
• Closing dimension: At bend sequence computation the back gauge stop position will be chosen to get the resulting tolerances in this line interval.

Example:

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’.

Bend Properties

Air bend

The DELEM DA-66T excels in complex bending operations. It supports various bending methodologies, including Air Bend, which is ideal for achieving precise angles with minimal tooling. The bend properties can be set by selecting the bend and selecting Properties.

1. Bend Type:
   • Air Bend: This is a standard bending process involving a defined angle and a preferred radius.
   • Bumping: Utilized to achieve a large radius by performing multiple steps of air bending.
   • Hem Bend: Includes both a pre-bend, which is a standard air bend with a sharp angle, and a hemming action executed with a specialized hemming tool.
2. Angle:
   • The angle value specified determines the degree of bending required in the process.
3. Preferred Radius:
   • This is the intended radius of the bend and is initially set to the thickness of the product. Large radius tools are necessary if programming for a large radius.
4. Computed Radius:
   • This is the resulting radius calculated based on the control settings and the tools used in the bending process. A special large-radius punch is required for bending large radii, but if unavailable, the bumping method can be used. Ensure that the radius value does not exceed the length of any adjacent sides.
5. Flange End Bend Creation:
   • Bends can also be created by placing the cursor on the flange end where the bend is desired and selecting ‘Properties’. This brings up a pop-up window to input additional parameters.

These elements are crucial components for accurately implementing DELEM DA-66T Product Drawings and ensuring precise bending according to design requirements.

Large Radius: Bumping

For complex curvatures, Large Radius: Bumping ensures smooth and consistent results.

The bumping method in DELEM DA-66T Product Drawing requires precise programming of several key parameters to achieve the desired bend and radius in your product design:

1. Central Angle:
   • Program the central angle, which represents the supplemental value needed to achieve the intended bend.
2. Radius:
   • Define the intended radius of your bend. Start by using the programmed product thickness as the initial value.
3. Number of Segments:
   • Specify the number of segments into which the radius will be divided. Each segment represents an individual bend, with the total number of bends being one more than the number of segments. A higher number of segments allows for a more precise radius with a smaller tolerance, but requires a smaller V-die opening for accurate bending.
4. Equal Bumping-Segments Option:
   • Decide whether to enable or disable equal bumping-segments:
     • Enabled: All segments will have equal size, simplifying the die selection process.
     • Disabled: Standard calculation involves half-size segments at the start and end, which might complicate die selection. If a V-die size problem is detected, the system will prompt for recalculation with equal-sized segments.
5. Programming the Bend:
   • Initially, program a standard angle with adjacent sides. Then, select the angle, tap on ‘Properties’, and choose ‘Bumping’ as the Bend Type. Program the radius, the number of segments, and decide on equal bumping segments. The system will then draw the radius in the product and provide information on the smallest calculated segment length, which influences the die selection.

By following these steps, you can implement precise and effective bumping methods in their DELEM DA-66T Product Drawing, facilitating accurate bends and contributing to optimal product design.

Hem Bends

Additionally, it supports Hem Bends, providing the capability to create strong, finished edges that enhance product durability and aesthetics. The bend properties can be programmed in the pop-up window.

Bend Properties

1. Prebend Angle:
   • The prebend angle is the required angle for the initial bend, typically set to a sharp angle for precision.
   • The default angle is set to 30 degrees, but it can be adjusted to an optimal value based on practical requirements.
2. Hem Opening:
   • This refers to the specific opening distance between the two flanges during a hem bend.
   • The hem opening value influences the calculation of the beam position during the hemming process.
   • By default, this parameter uses the value defined in the Settings mode parameter ‘Default Hem Opening.’

Side Properties

• Side Length:
  • This parameter specifies the length of the flange to be hemmed, which is crucial for accurate drawing execution in the DELEM DA-66T Product Drawing.

By understanding these properties, users can effectively implement DELEM DA-66T Product Drawing, ensuring precision and accuracy in the bending and hemming processes.

Surface or Bend Line Marker

Marking is a critical step in ensuring accuracy and quality in production. The DELEM DA-66T includes features for Surface or Bend Line Marker placement, guiding operators to align materials precisely for accurate bends.

Functions:

1. Set Marker:
   • A cylindrical ‘label’ identifies the point of insertion, aiding in precise modifications or inspections.
   • Users have the flexibility to move the marker to a new location by repositioning it accordingly.
   • The marker is visible in Automatic mode, providing clear visibility during operations.
2. Flip Marker: Users have the option to swap the top and bottom colors of the marker.
3. Remove Marker: Users can remove the marker from the product drawing when it is no longer needed.

This feature ensures consistency across runs and minimizes errors during setup and execution.
