In such cases, revisit the tool configuration menu to correct errors, or adjust the assignments menu as needed. If a collision is detected during unbending, manually adjust the bend sequence using the available functions for optimal results. Mastering these techniques ensures an efficient DELEM DA-69T Bend Sequence workflow.

Manual Selection of Bends

In DELEM DA-69T systems, while the control usually suggests the next bend in the sequence, manual adjustments may be necessary to optimize the DELEM DA-69T Bend Sequence. This can be done through the Manual Selection function, allowing users to modify the sequence based on specific needs.

Upon activation, the Manual Selection offers two methods:

1. Start with a Bent Product: Users can specify the unbend sequence by tapping on bends, adding them to the sequence. The process begins from the highest number and goes to bend 1.
2. Start with a Flat Product: Users can set the bend sequence by selecting bends, starting from bend 1 to the highest number.

If a bend already in the sequence is selected, the DELEM DA-69T system resumes the sequence from that point. This flexibility helps users master the DELEM DA-69T Bend Sequence efficiently, enhancing their bending operations.

Assignments – general

In mastering the DELEM DA-69T Bend Sequence, it’s crucial to understand several configuration parameters that can significantly impact your bending process.

The optimisation degree is one of these key parameters, ranging from 1 to 5. This value determines the number of alternatives computed for each bend. A higher number indicates more alternatives are examined, though it results in longer computation times:

1. Lowest optimisation, fastest computation.
2. Low optimisation, fast computation.
3. Medium optimisation, medium computation.
4. High optimisation, slow computation.
5. Highest optimisation, slowest computation.

Optimizing the DELEM DA-69T Bend Sequence involves key configuration parameters:

Front Extend Ratio: This ratio (0.01 – 1.0) ensures there’s enough product length in front of the press for handling. Options include Comply If Possible, where the system tries to adhere to the ratio when viable, and Comply Always, strictly enforcing the ratio even if it limits solutions.

Radius Factor: With a range from 0.1 to 2.0, this factor adjusts the computed bend radius to refine X-axis position and blank length based on material properties, optimizing the DELEM DA-69T Bend Sequence.

Tool Length Tolerance: This sets the allowed difference between tool length and bend line length, ensuring the tool’s length is sufficient for the bend, impacting sequence execution.

Minimum Y Opening: Determines the pressbeam’s optimal opening for product handling, programmed above the speed change point for efficient operation.

By configuring these settings, you can master the DELEM DA-69T Bend Sequence, enhancing precision and product quality.

Assignments – Backgauge possibilities

Mastering the DELEM DA-69T Bend Sequence requires a thorough understanding of backgauge possibilities. Here are key considerations:

Backstop Against Sharp Angle: Determine whether the backstop can be placed against angles smaller than 90°. Options include allowing it (“Yes”) or not (“No”), which influences how you manage the DELEM DA-69T Bend Sequence.

Backstop-Die, Intermediate Bend: Decide if bends are permitted between the die and backstop. The choices are:

• “Permitted”: if it’s routinely allowed.

• “Permit if unavoidable” if it results that no solutions are to be found, than it is permitted.

• “Prohibited”: never allowed.

This decision ensures precision in executing the DELEM DA-69T Bend Sequence.

Edge Tolerance: When the backstop is against a flat sheet, an angle tolerance (deviation from horizontal) is permissible. This is programmable in degrees, ranging from 0 to 90°.

90 Degree Tolerance: Establish the maximum allowed deviation from vertical (90°) when a backgauge is against a bent angle.

Lay-On Backstop Limit: Utilize this parameter if the press brake features backgauge fingers on a moving R-axis with a “lay-on” design. If the sheet’s length exceeds this limit at the machine’s backside, automatic corrections to the X and R-axis positions occur, allowing the sheet to rest on the backgauge finger.

Retract Optimization: Enhance process efficiency by enabling retract optimization for graphical bend steps. This feature optimizes during the post-processing stage, ensuring the backgauge moves directly to its next position, thus streamlining the DELEM DA-69T Bend Sequence.

Understanding these assignments is crucial in ensuring the precision and efficiency of the DELEM DA-69T Bend Sequence, thereby enhancing overall performance.

Show bend sequence

When the function Show Bend Sequence has been pressed, a graphical overview of the bend sequence is shown.

This feature can be accessed anytime after the initial unbend is completed. The graphical overview showcases determined bends and those still pending (indicated by a question mark).

Each image in the overview can be individually zoomed in or out using available functions and rotated with finger movements. This functionality aids in optimizing the DELEM DA-69T Bend Sequence.
