Nesting (process)

As boxes the space-saving positioning of parts during storage, storing, packing or for cutting is called.

Cut out

For cutting of primitives from an area they are arranged in a space -saving. For example, individual sheet metal parts that are to be gained from a metal sheet by nibbling, laser cutting or water jet cutting, nested. Also, when cutting pieces of fabric in the textile industry, leather or fur parts from animal skins, the cutting of tiles, pieces of wood from boards.

In addition an arrangement of parts, which facilitates the subsequent cutting, in particular, is set to minimize the blending value.

The simplest method of nesting consists of a simple rectangular arrangement in which the cut out elements are wrapped in rectangles which are then arranged in rows ( Fig. 1). Better algorithms also take account of the possibility to rotate the elements, to thereby push them close together can ( Figure 2). In practice, moreover, an attempt is made to use remaining free areas by smaller or differently shaped elements ( Fig. 3).

Packing

When packing is to be saved by favorable arrangement of the contents of packaging materials and storage volume, while ensuring packaging security and stacking strength. As basic shapes have been proven: box, cylinder, Tetrapak. More complicated shapes are secured by special packing holder, in the resulting cavities other parts are packed (example: cable and remote control during the TV).

Dam

When stowing it comes to best use an existing space, such as the hold of a ship, a truck or the trunk of a car.

Storage space is expensive, so parts are stored to save space. It is important to simultaneously ensure that both the storage and the retrieval and removal easy, can be done quickly and safely.
