AutoPanelSizer – optimized cutting layouts for panel-sizing saws

The AutoPanelSizer ­software determines optimized cutting layouts for the ­production of rectangular parts from rectangular raw material and minimizes waste, production times and manufacturing costs. ­AutoPanelSizer generates layouts that can be produced with so-called guillotine cuts, i.e. straight end-to-end cuts. In case of ­interlinked plants, the maximum number of cutting stages is taken into account. ­This makes the software suitable for common cutting technologies applied in the machining of wood and also in the glass, metal and plastics processing industries.
 

Cutting layouts in seconds

AutoPanelSizer can compute layouts with up to three cutting stages plus head cuts on the first stage (see examples). On the third cutting stage, it is possible to only recut individual parts or to separate multiple parts. The software is able to comply with miscellaneous constraints ­given by machine or material properties.

Available remnants and various sizes of raw sheets can be included in the ­optimization. The computation of a typical ­cutting layout takes from only a few seconds to just a few minutes. When using multiple processor cores (by bundling of licenses), the runtime can be further reduced.

Reduced production costs – increased yield

In the optimization process, the software considers both production times and ­manufacturing costs. It can weigh time-­consuming processes, such as head cuts or the storage of remnants, against a more efficient material utilization. By ­combining identical cutting plans into ­packages, ­simultaneous cuts are feasible thereby reducing production time. ­AutoPanelSizer offers various possibilities to control the generation of such package cuts. Tensions in the material can lead to bent cut edges. To prevent this, AutoPanelSizer can insert stress release cuts, which improve the cut quality.

Furthermore, each part to be produced may be assigned to a part group. This allows for destacking restrictions as well as ­requests regarding a production sequence to be taken into account. In connection with part groups, the optimization can also be carried out across different material types.

Anticipatory planning by optional overproduction

In AutoPanelSizer, parts may be declared as required (compulsory) or optional. The former have to be placed on the cutting layouts, the latter are only placed if they fit well and improve the yield. For example, parts that are needed the next day can be declared as required, while parts that are needed later can be declared as optional. This anticipatory production improves the efficiency of the cutting layouts and reduces the overall material consumption.

Integration into existing software

AutoPanelSizer is distributed as a pure geometric optimization engine and can easily be integrated into other applications, such as plant control systems, MES, or ERP systems. For this purpose, AutoPanelSizer has an XML interface that can be used via standard input/output, files, or network service. The software runs on all current Microsoft Windows operating systems.

AutoPanelSizer addresses two groups of customers,

• software solution providers who want to integrate an optimization into their application and
• companies that are willing to program a corresponding connection to their IT systems or ask their IT service provider to do so.

To give you an impression of the performance of our software before you integrate it into your systems, we offer a demo GUI. This simple GUI is not suitable for daily productive use.

Based on the latest research results, Fraunhofer SCAI constantly improves and enhances AutoPanelSizer. AutoPanelSizer benefits from the expertise of the institute in optimization.
