OptiNest® is a powerful automated nesting and CNC programming software package for fabricators using flame (oxy-fuel or plasma) and waterjet machine tools. The flow chart below illustrates how the features of this software work together to deliver the range of benefits OptiNest® users enjoy.
In addition to the information below, you can click on any of the modules identified here for a more detailed explanation of how it works.
Working with Part Designs
CAD drawings along with pertinent pre-programmed inputs and manufacturing attributes are imported into Optimation® software. OptiNest® is compatible with a wider range of CAD formats than any other nesting software.
From CAD to CAM
The software automatically checks and cleans the CAD geometries and translates them into an NC Part Program . . . or alerts you if errors are present. It also assigns the machining process and creates the tool paths. Parts are stored in the Master File of the Part Library to allow for quality control mechanisms such as First Article Inspection and engineering changes.
OptiNest® also:
- Automatically creates lead-in/lead-out and pierce technology.
- Automatically sets feed rates and power setting based on geometry.
- Applies feed rate and kerf compensation per material definition.
A Storehouse of Knowledge
Material, machine and tool parameters are stored in the Knowledge Base, along with other key attributes about your operation. Similarly, design and key values of the ready-to-nest part program are stored in the Part Library where they are available for immediate use. Considered together, these variables can be used to create the most "intelligent" nesting pattern possible . . . i.e. the one best suited to the needs of your situation.
OptiNest® also provides a full-featured Common Cutting approach that allows the user to specify which parts can be common edge cut when a part is libraried.
Entering The Orders
Users can manually key orders into OptiNest® directly, or it can be interfaced to any scheduling system that outputs an ASCII file, eliminating the need to manually re-enter. Orders are automatically checked to ensure that the part can be produced and "flagged," if needed (for First Article Inspection, for example, or if engineering changes are detected). All clean orders are placed in the Active Order File while those not passing inspection are sent to the Suspended Orders File.
Creating the Nest
This module enables the software to read the Active Order File for the current demand of parts, extract the appropriate ready-to-nest parts from the Part Library's Master File and, drawing on the parameters you have established in the "Knowledge Base," create the optimal nesting pattern. The Nesting Module's ability to use several intelligent tools to create the nest is one of the primary advantages of Optimation's® software and, ultimately, the feature that enables you to get the parts you need, when you need them, in their exact quantities, at the lowest cost.
OptiNest® also:
- Creates nests for fixed or variable torch settings (using "like" or "mirror" image cutting techniques) on single or multiple plates
- Automatically creates lead-in/lead-out based on a lead-in library
Communicating with the Operator and Machine Tool
Finally, the nest code is sent to the machine tool for fabrication in machine specific numeric code. In addition, the software automatically generates a nest summary report and plot to give the operator a comprehensive overview of each nest.
- Provides NC code for driving marking and scribing devices automatically, even for multi-torch operations.
- Drives single and multiple head beveling operations.
- Allows for interactive tool path modification such as chain linking and edge-starting of parts, change in path direction.
- Automatically drives machines with automatic torch spacing capability.
- Recognizes when the master torch cannot reach all parts on the plate and automatically utilizes an alternate torch.
- Outputs NC or ESSI formats.Provides a selection of various cut order options in order to accomplish optimization while minimizing plate distortion due to heat dissipation.
- Provides (through beveling configuration table) bevel angle, offset, and on/off information for automatically attributing bevel geometry; including automatic corner looping.
