Lantek Expert is a premier CAD/CAM nesting software designed to automate the CNC programming of sheet metal cutting machines (laser, plasma, oxy-fuel, waterjet, and punch).
This guide outlines the standard workflow to take a project from a digital drawing to a machine-ready CNC file. 1. Drawing and Part Import
The first step is bringing your geometry into the Lantek environment.
Importing Files: Most users import external files like DXF, DWG, or IGES. Use the Import command to bring these into your "Part Library."
Drafting: If you don't have a file, you can use Lantek’s internal CAD tools to draw shapes, add chamfers, or create offsets.
Cleaning Geometry: Use the "Clean" or "Verify" tools to ensure there are no open contours or duplicate lines, which can cause errors during the cutting process. 2. Defining Part Properties
Once the geometry is ready, you must tell the software what it's looking at.
Material and Thickness: Assign the specific material (e.g., Mild Steel, Stainless, Aluminum) and the sheet thickness. This determines the cutting parameters (feed rate, gases, etc.) used later. lantek expert tutorial
Quantity: Specify how many of each part you need to produce.
Grain Direction: If the material has a finish (like brushed stainless), you can lock the part's rotation to ensure it aligns with the material grain. 3. Nesting Strategy (Automatic vs. Manual)
Nesting is the process of arranging parts on a metal sheet to minimize waste.
Automatic Nesting: Lantek’s engine can automatically calculate the most efficient layout for multiple parts across multiple sheets. You can set "Minimum distance between parts" and "Distance to sheet edge" to prevent collisions or heat deformation.
Manual Nesting: For complex or high-priority jobs, you can manually drag and drop parts onto the sheet. You can use the rotation settings to squeeze parts into tight gaps.
Remnant Management: If you don't use a whole sheet, Lantek can save the "scrap" as a new sheet (Remnant) in the database for future use. 4. Machining and Lead-ins This stage defines how the machine will cut the paths.
Lead-ins/Lead-outs: Add entry points (Leads) so the initial pierce doesn't damage the finished edge of the part. You can choose between straight, circular, or "hook" leads. Lantek Expert is a premier CAD/CAM nesting software
Cutting Order: You can let the software optimize the path (usually starting from the center of the sheet and moving out) or manually pick the sequence to manage heat build-up.
Micro-joints: If you are cutting small parts that might tip over and hit the laser head, add "Micro-joints" (small tabs) to keep the part attached to the skeleton until the operator removes it. 5. Simulation and G-Code Generation
Before sending the file to the machine, you must verify the work.
Simulation: Run the visual simulation to check for collisions, incorrect cutting orders, or missing pierces.
Post-Processing: Once satisfied, click "Generate CNC." This converts your visual nest into G-Code specific to your machine's controller (e.g., Fanuc, Siemens, Mazak).
Work Reports: You can print a "Workshop Report" that shows the operator the sheet layout, estimated time, and the weight of the parts produced.

You have now mastered the core Lantek Expert workflow: part management → nesting → technology assignment → NC generation. With consistent practice, you will reduce material waste up to 8‑12% and decrease machine idle time by optimizing toolpaths and sequences.
“Better nesting today means more profit tomorrow.”
Next steps: Experiment with remnant reuse, multi‑sheet nests, and custom post‑processor edits.
Overall Verdict: 6.5/10 (Functional but fragmented)
Lantek Expert is a powerful, industry-specific nesting software for plasma, laser, and punch presses. However, the "tutorial ecosystem" is a classic case of powerful software with mediocre learning materials. You will likely need a mix of official documentation, YouTube scavenger hunting, and hands-on trial-and-error.
