The GTR Nest Management nesting process in detail:
GTR Nest Management is performing true shape nesting, where the parts required can be any odd shape. The individual parts are created using PASCAM WoodWorks and PASCAM Bea, based on SolidWorks^®, then a .xml file is generated by PASCAM WoodBatch to kick off the nesting optimization by the GTR postprocessor.
For example a 3D assembly model of a cabinet (see picture below) can be created with the PASCAM WoodWorks Part description in SolidWorks^®. Using GTR Nest, this assembly is unfolded into the cabinet's flat case parts on the raw sheet, while considering the correct compliance of the material type, the material thickness and the grain direction of the raw sheet with the model parts. The flat case parts can then be nested and the CNC code is generated with our woodworking CAM module PASCAM Bea for profile cutting for optimal material utilization. As an alternative, the nesting job editor can be started directly from the application. Any subsequent changes are then stored in a file. The "ReNest" function will then launch a fresh nesting job and create a XML file for the machine control, including those adjustments.

Based on PASCAM Bea's superior CAM programming technology and the woodworking engineering enhancements delivered by PASCAM WoodWorks, the powerful nesting technology in GTR Nest Management enables the safe and reliable extraction of manufacturing data and generation of CNC code for true shape nesting, based on 3D SolidWorks^® model assemblies.
Through GTR Nest Management's true shape nesting algorithm, GTR Nest supports bridges, ”onion skin” cutting, parts in parts and remnant nesting with small part threshold nested in the center of the sheet.

The GTR Nest Management true shape nesting gives you the power to:

•  Manage the raw material boards are using a sheet stock. Sheets can be manually selected from this stock for nesting. As an alternative the program can retrieve suitable boards automatically from the sheet stock.
•  Nest the parts automatically, according to the job order. Nesting job is created by dissolving the SolidWorks^® assembly.
•  Manually compile the nesting job. The nesting job can take place per job or per order (as a SolidWorks^® assembly) or via a arbitrary part compilation.
•  Test the material thickness, material type and grain direction of the raw board and the model parts for correct conformity.
•  Print out of the nesting results as a drawing.

Additionally there is a facility to print out of freely configurable adhesive labels, including the print out of the drawings. And there are also powerful, enhanced part retention methods available:

•  Automatically preventing milling through at small parts, as of a certain workpiece size (onion skin). Parameter: Remnant thickness
•  Automatically adding or setting of bridges (depending on the workpiece size). Parameter: Length, Number and Thickness of bridges
•  Automatically positioning of small parts in the centre of the raw board (if the workpiece size is smaller than a certain threshold value the part is placed at the center of the sheet). Variable: Prohibited boundary

GTR Nest Management business benefits:
GTR Nest is supporting nesting jobs on any capable woodworking CNC router machine. Especially if you are operating CNC machines from more than one vendor, you will save a lot of money using GTR Nest Management to control the different machines with a single work seat installation. Saving not only additional license fees but also on training and support costs for your staff, due to staying in the SolidWorks^® CAD environment and not having to learn several different software packages of 3rd party vendors.
Automatic nesting ensures optimal utilization of material, allowing more parts to be produced from less material. Machine motion optimization using advanced PASCAM Bea CNC programming ensures minimum machine cycle time, increasing the production capacity of your existing equipment.
