Overview of OptiNest V3.05
Table of Contents
OptiNest V3.05 is a professional-grade CNC nesting software developed by CADCode Systems and Boole & Partners. It is designed to optimize material usage and cutting efficiency for manufacturing industries . The software uses advanced nesting algorithms to automatically arrange 2D parts on sheet materials, reducing waste and maximizing yield for CNC machining operations .
This CAD nesting software supports various cutting technologies, including plasma, laser, waterjet, and router-based cutting systems . By intelligently positioning parts on raw material sheets, OptiNest helps manufacturers reduce material costs, minimize machine time, and improve overall production efficiency. The software accepts DXF file imports for part geometry and exports optimized nesting layouts ready for CNC tooling .
OptiNest is available in several versions to accommodate different production needs: ON-LT (Light version for basic shapes), ON-Std (Standard version for all polyline shapes), and ON-Pro (Toolings version for bored and tooled pieces) .
Key Features
Advanced Nesting Algorithms
The software employs powerful algorithms based on the BOOLE & PARTNERS CalepiLib functions library . Key computational parameters include calculation depth, smoothing factor, pieces grouping, and propagation mode. These algorithms analyze part geometry and sheet dimensions to determine the most efficient arrangement, minimizing gaps and maximizing material utilization.
True-Shape Nesting for Irregular Parts
OptiNest excels at handling non-rectangular shapes. The software can nest irregular shapes by considering the smallest rectangle that contains each part . For complex curved or polygonal components, the optional true-shape nesting feature fits shapes within shapes, reducing space between parts and increasing the number of parts per sheet .
Multiple Operation Integration
Nesting integrates seamlessly with other machining tasks, including drilling, routing, dados, and pocketing . OptiNest optimizes the movement of router heads to minimize travel time and reduce overall cycle times. When processing a job, the software can simultaneously generate machining programs, part labels, and production reports .
Panel Editor for Manual Adjustments
For situations requiring customized nesting layouts, the OptiNest Panel Editor allows users to view cutting patterns and manually move parts . After adjustments, the software automatically generates updated cutlists and fresh machining programs. This feature provides greater control for specialized production requirements.
Small Part Management
Small parts present unique challenges in CNC machining due to reduced vacuum holding force. OptiNest addresses this with multiple control options, including tabs and onionskinning, multiple machining passes, and intelligent nesting algorithms that connect small parts to larger parts until final release .
Bored Parts and Hole Integration
OptiNest handles bored pieces by treating holes as specific tooling types . The software can recover material from part holes and reuse it for placing smaller components, further improving material efficiency. This feature is particularly valuable for industries manufacturing parts with cutouts or openings.
DXF Import and Export
The software supports importing part outlines, toolings, and inner openings in DXF format . Outlines can be described using closed polylines or sequences of open polylines, arcs, and lines. After optimization, nesting maps can be exported in DXF format for transfer to CAD software or CNC machines.
Direct Shape Entry
In addition to DXF import, OptiNest offers quick entry of rectangular, circular, and polygonal shapes directly within the software . This feature is useful for creating simple parts without requiring external CAD tools.
Customizable Labeling
OptiNest provides customizable labeling configurations, including QR codes and barcodes . Labels include essential information such as placement guides, rotation indicators, and edge banding details, facilitating efficient production tracking.
