AutoPanelSizer software determines optimized cutting layouts for the production of rectangular parts from rectangular base material, minimizing waste, production times and manufacturing costs.

AutoPanelSizer computes this cutting layout in 0.3 seconds. It has been taken into account that only 3 destacking stations are available. Parts with the same color must be destacked together.

Cutting layouts in seconds

AutoPanelSizer can compute layouts with up to three cutting stages plus head cuts and considers different constraints imposed by the cutting process and the material. Available remnants and various sizes of raw sheets can be included in the optimization. The computation of a typically sized cutting layout takes only a few seconds to a couple of minutes and can be further reduced using multiple processor cores.

Benefit & value

AutoPanelSizer considers production times and manufacturing costs and weighs time-consuming operations, such as head cuts, recuts, destacking, or remnant storage, against a more efficient material utilization. Production time is reduced by sawing several sheets at the same time in a package cut. Tensions in the material can lead to bent cut edges. To prevent this, AutoPanelSizer can insert stress release cuts for better cut quality. Destacking restrictions of finished cut parts can be taken into account via part groups, as can requested production sequences, even across multiple materials. AutoPanelSizer supports a maximum allowed overproduction that can be set per part: a few additional parts may be placed on the cutting layout to improve the yield.

Target groups

Providers of software solutions who would like to integrate optimization into their application, as well as larger companies who are willing to program or have programmed a corresponding interface to their IT systems.

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.

Integration into existing software

AutoPanelSizer is distributed as a pure geometric optimization engine and is intended for integration into other applications, for example plant control systems, MES or ERP systems. For this purpose, AutoPanelSizer has an XML interface that can be accessed via standard input / output, via a file interface or as a server service. The software runs on all current Microsoft Windows operating systems.
