ESA S875 Manual Calculation is the right solution when greater control over the bending sequence is required. If you are looking for a clear explanation of how to efficiently use ESA S875 Manual Calculation, this article directly addresses that need. In this guide, I explain when manual calculation should be applied, how it differs from automatic calculation, and how operators can actively define or adjust bending sequences to suit complex parts. By understanding the logic and workflow behind ESA S875 Manual Calculation, it becomes easier to reduce calculation conflicts, manage collisions, and achieve stable, accurate bending results in daily press brake operations.<\/p>\n\n\n\n

Accessing the Manual Calculation Procedure<\/h2>\n\n\n\n

Open the Calculation Window<\/h3>\n\n\n\n

The manual calculation procedure is accessed from the drawing mask of the piece:<\/p>\n\n\n\n

    \n
  1. Press [Calculate<\/em>]<\/strong> to open the calculation window.<\/li>\n\n\n\n
  2. The window displays the part along with the press brake components, including the upper and lower beams, punch, die, and backgauge.<\/li>\n\n\n\n
  3. Three additional windows on the right show rotation counts, piece tipping, and bending sequence search results.<\/li>\n<\/ol>\n\n\n\n
    \"\"<\/figure>\n\n\n\n

    These features provide a comprehensive overview, allowing operators to analyze potential collisions and feasibility before bending begins.<\/p>\n\n\n\n

    Defining the Bending Sequence<\/h2>\n\n\n\n

    Manual Search for Bends<\/h3>\n\n\n\n

    In ESA S875<\/a> Manual Calculation, the operator defines the sequence by forcing bends:<\/p>\n\n\n\n

      \n
    1. Navigate between bends using the arrow keys<\/strong>.<\/li>\n\n\n\n
    2. Press the [Bend<\/em>]<\/strong> key to force a selected bend into the sequence.<\/li>\n\n\n\n
    3. Press [Bend<\/em>]<\/strong> again to remove or straighten a forced bend.<\/li>\n\n\n\n
    4. Rotate the part using the [Rotate<\/em>]<\/strong> key if required to check orientation.<\/li>\n\n\n\n
    5. After all desired bends are forced, press [Optimise<\/em>]<\/strong> to allow the control to calculate the remaining sequence while respecting the operator’s inputs.<\/li>\n<\/ol>\n\n\n\n

      Sequence Feasibility<\/h3>\n\n\n\n

      ESA S875 Manual Calculation provides feedback:<\/p>\n\n\n\n

        \n
      • Forced Solution<\/strong>: Indicates the sequence is not feasible due to collisions or constraints.<\/li>\n\n\n\n
      • Solution Found<\/strong>: Confirms the sequence is feasible and ready to be accepted.<\/li>\n<\/ul>\n\n\n\n

        Collisions are highlighted visually, helping operators identify problematic bends. Even if collisions are minor and do not damage the metal sheet, the full sequence can be forced to proceed.<\/p>\n\n\n\n

        Simulation of the Manual Sequence<\/h2>\n\n\n\n

        Step-by-Step Simulation<\/h3>\n\n\n\n

        After accepting the solution, simulate the bending sequence:<\/p>\n\n\n\n

          \n
        1. Press [Simulate<\/em>]<\/strong> to display the flat part ready for bending.<\/li>\n\n\n\n
        2. Use [Resting against\/supported<\/em>]<\/strong> to select how the part rests or is supported.<\/li>\n\n\n\n
        3. Press [Continue<\/em>]<\/strong> to move the part through each bend in sequence.<\/li>\n\n\n\n
        4. Use [Stop<\/em>]<\/strong> and [Previous<\/em>]<\/strong> to control simulation flow.<\/li>\n<\/ol>\n\n\n\n

          This ensures each bend is executed accurately and confirms the sequence is safe and efficient before actual production.<\/p>\n\n\n\n

          Resting Against \/ Supported Mode<\/h3>\n\n\n\n

          Operators can define the bending support:<\/p>\n\n\n\n

            \n
          • Select the resting or supported position as needed.<\/li>\n\n\n\n
          • ESA S875 Manual Calculation automatically adjusts X and R axis corrections.<\/li>\n\n\n\n
          • Changes must be made in the simulation mask for graphic programmes.<\/li>\n<\/ul>\n\n\n\n

            Modifying the Sequence<\/h2>\n\n\n\n

            Even after optimisation, ESA S875 Manual Calculation allows sequence adjustments:<\/p>\n\n\n\n

              \n
            1. Move between bends using navigation keys.<\/li>\n\n\n\n
            2. Remove or reassign bends using the [Bend<\/em>]<\/strong> key.<\/li>\n\n\n\n
            3. Reorder bends according to production requirements.<\/li>\n<\/ol>\n\n\n\n

              This flexibility ensures that manual calculations remain practical and adaptable, accommodating production changes without redrawing the entire part.<\/p>\n\n\n\n

              Frequently Asked Questions(FAQ)<\/h2>\n\n\n
              \n
              \n
              \n

              When should ESA S875 Manual Calculation be used instead of automatic calculation?<\/h3>\n
              \n\n

              ESA S875 Manual Calculation is recommended when automatic calculation cannot find a feasible bending sequence or when the operator needs precise control over bend order. This typically occurs with complex geometries, large parts, or situations where specific bends must be performed first to avoid handling issues or collisions.<\/p>\n\n<\/div>\n<\/div>\n

              \n

              How does ESA S875 Manual Calculation help avoid collisions?<\/h3>\n
              \n\n

              During ESA S875 Manual Calculation, the system visually highlights collisions by changing the color of the part areas that interfere with machine components. This allows operators to identify problematic bends early and adjust the bending sequence manually before production begins.<\/p>\n\n<\/div>\n<\/div>\n

              \n

              What does a \u201cForced Solution\u201d message mean in manual calculation?<\/h3>\n
              \n\n

              A \u201cForced Solution\u201d message indicates that the bending sequence defined by the operator is not fully feasible under standard conditions. This may be due to collisions or machine limits. In some cases, the operator can still proceed if the collision does not affect part quality or machine safety.<\/p>\n\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\n\n

              Conclusion<\/h2>\n\n\n\n

              ESA S875 Manual Calculation provides operators with full control over the bending sequence, making it an essential function when automatic calculation cannot deliver an optimal or feasible result. By manually forcing bends, adjusting rotation, and validating each step through simulation, complex parts and challenging geometries can be handled with greater accuracy and confidence.<\/p>\n\n\n\n

              Proper use of ESA S875 Manual Calculation helps reduce collision risks, improves bending precision, and ensures that the final bending sequence aligns with real production requirements. Combined with simulation and resting-against or supported modes, this method enhances overall process reliability and machine efficiency.<\/p>\n\n\n\n
