FDM

MAXIMIZING

a production run, not one hide after another. It’s optimal because the nesting takes place over a larger number of hides than previously possible. It is dynamic because the algorithms will adapt to the quality of incoming hides.

Manufacturers are able to obtain a fine cut (less than .005 inch) with this system’s precision, omni-directional

cutting. As many notches, holes and slits as required can be programmed onto the pattern. The real advantage, however, is the ability to overlook kerf, plunge lines, overcuts, tool orientation and tool thickness when cutting.

Flexible tool

Because all this takes place off line, manufacturing now has a tool that is also flexible. Production runs can be

interrupted, mixed and scheduled as required because the system maintains a part count.

Parts cutting and stacking completes the process. Since Expert Systemtechnik wasn’t forced to adapt an existing technology, it chose a waterjet system.

The head is lightweight, which allows Expert to build a cutting table with speeds of up to 200 feet a minute in contouring mode. The jet is ultra fine and unidirectional. Cutting can be started or stopped anywhere on the part, permitting holes, slits and sewing notches to be very small. Common cut lines are now possible, and the nesting and cutting programs need to waste no time, motion or leather to compensate for tool orientation or thickness.

The Force in Air

The waterjet system exerts no lateral force on the leather, which eliminates the need for foils and vacuum to hold the part. Even organically dyed leathers are not influenced in any way by the waterjet because it slices through the leather.

The bar code label communicates the hide surface form to the overhead laser projector system, which projects the outline of the hide exactly as it was scanned. The cutting surface of the shuttle table is slightly sticky, which will hold the leather down regardless of its furls and tendency to curl.

Accurate parts count

Once cut, the same laser projector will tell the operators in which bin to place the part. The system produces the exact number of parts needed.

The system is available in single and dual gantry, as well as single and dual shuttles. Because the system is modular, it can work with laser projection to use clicker knives and rotary presses for those shops that have smaller throughput requirements. Customers typically have a one-year payback on a one-shift operation, less on operations with two shifts.
