Production Time Calculation

In the DELEM DA-66T Settings Mode, the following parameters can be configured to optimize the production time calculation of the bending sequence, ensuring that the time estimation accurately matches the actual operation process:

Production Time Calculation Logic

The calculation of production time mainly depends on the axis positioning speed and product handling time. Among them, the axis positioning speed is determined by the machine settings, and the handling time is directly related to the product size (especially length and width)—small products have higher handling efficiency, while the flipping operation of large strip-shaped products requires more time.

Turn Time Configuration

The flipping time of products of different sizes can be set through a table (unit: seconds). The table divides product lengths into four intervals, and each interval corresponds to preset times for different flipping types (top-bottom flip, front-back flip, combination flip). At the same time, three length boundary values (Boundary 1, Boundary 2, Boundary 3) can be customized to achieve accurate adaptation of flipping times for products of different sizes.

By adjusting these parameters, the production time calculation can be more in line with the actual operation scenario, providing a reliable basis for production plan formulation.

Time Settings

Configuring accurate system time can ensure the complete traceability of all machine operation records and keep them synchronized with the project timeline. The specific configurable options are as follows:

• Display Time: Select the time display form of the title bar (display date and time, display time only, no time display).

• Time Format: Select the time display format (24-hour format or 12-hour format).

• Date Format: Select the date display format (dd-mm-yyyy, mm-dd-yyyy, or yyyy-mm-dd).

• Adjust Time: Manually modify the system date and time. This operation will synchronously update the date and time of the Windows operating system.
