Nesting

Nesting is an algorithm of automated part allocation on a metal sheet the most convenient and efficient way. There are many software solutions for sheet metal component nesting, enabling various methods for automated and interactive part allocation and achieving optimal results of resource usage.

The nesting module analyzes the parts (shapes) to be produced at a particular time. Using proprietary algorithms, it then determines how to lay these parts out in such a way as to produce the required quantities of parts, while minimizing the amount of raw material wasted. While some software solutions cater only to rectangular nesting, others offer profile or shape nesting where the parts required can be any odd shape.

The most efficient part allocation on a sheet is achieved by arranging the best part combination, employing mirroring and rotation techniques where required. Some nesting modules allow to modify approximation degree and part allocation with an applied technological process. Rotation angle allowances, minimum distance between parts and nesting direction parameters can be set.

Many metal processing machine manufacturers offers their in-house nesting solutions in order to use all the benefits and technological specifics of the processing equipment.

The main benefits of using nesting technology in manufacturing are:

• Maximum usage of raw material, allowing to reduce time and financial costs of manufacturing
• Efficient usage of metal remnants, cutoffs and scrap.
