Lantek Expert transforms manual programming into an automated, error-free workflow. By following this tutorial, you've learned how to import, nest, simulate, and post-process a sheet metal part. Regular use of simulation and microjoint features will drastically reduce scrap and machine downtime.
Remember: Always run a dry run (air cut) on a new CNC program before actual cutting.
Lantek Expert is a powerful CAD/CAM/Nesting software suite for sheet metal fabrication, used to optimize part programming, nesting, and machine cutting (laser, plasma, oxyfuel, waterjet, punching, and bending). This tutorial-style post gives a concise, practical walkthrough for new users to get productive quickly and adopt best practices.
Drawing a shape is not enough; the software must know what the shape represents.

Lantek Expert is the industry standard for CNC programming in sheet metal cutting. Whether you are operating a laser, plasma, oxy-fuel, or waterjet machine, mastering this software is essential for reducing waste and increasing shop floor efficiency. This comprehensive tutorial covers everything from the initial interface setup to generating the final CNC code. Understanding the Lantek Interface
When you first open Lantek Expert, you will see a workspace designed for a logical workflow. The top ribbon contains the main modules: Drawing, Nesting, and Manufacturing. On the left, you will find the Explorer tree, which organizes your parts, sheets, and jobs. The central area is your primary CAD/CAM workspace where you will visualize your nests and toolpaths.
Before starting a project, ensure your Machine Configuration is correct. This tells Lantek the specific capabilities of your CNC machine, such as maximum sheet size, nozzle offsets, and gas types. Using the wrong machine profile can lead to errors in the final G-code. Step 1: Importing and Preparing Geometry
Most workflows begin by bringing in a CAD file. Lantek Expert supports DXF, DWG, and various 3D formats. Click on Import and select your file.
Clean the geometry. Use the "Clean" tool to remove duplicate lines or tiny gaps that could confuse the cutting head.
Define the Part Attributes. Assign the material type (e.g., Stainless Steel) and the thickness (e.g., 2mm).
Set the quantity. Specify how many units of this part you need for the current production run. Step 2: Mastering the Nesting Module
Nesting is where Lantek saves you money by fitting as many parts as possible onto a single sheet of metal.
Manual Nesting: Drag and drop parts onto the sheet. Use the arrow keys to rotate parts. This is best for small jobs or odd-shaped remnants.Automatic Nesting: Click "Automatic Nesting" to let the Lantek algorithm calculate the best layout. You can set the "Nesting Quality" to high for complex shapes to minimize "skeletal" waste.Common Line Cutting: To save even more time and gas, use common line cutting. This allows the machine to cut the shared edge of two parts with a single pass. Step 3: Applying Machining and Toolpaths
Once your parts are nested, you must tell the machine how to cut them. This is known as "Machining." lantek expert tutorial
Lead-ins and Lead-outs: These are the entry and exit points for the torch. Ensure your lead-ins are placed on a straight edge or a corner to prevent "pitting" on the finished part.
Cutting Sequence: Use the "Sequence" tool to determine which parts are cut first. It is usually best to cut internal holes first, then move from the center of the sheet outward to prevent the metal from warping or shifting.
Micro-Joints: If you are cutting small parts, add micro-joints (tabs). These keep the parts attached to the skeleton so they don't tip over or fall into the scrap bin during the process. Step 4: Simulation and G-Code Generation
Never send a job to the machine without simulating it first. Lantek’s simulation tool shows a virtual representation of the cutting head moving across the sheet. Watch for potential collisions or inefficient rapid movements between cuts.
If the simulation looks good, click "Generate CNC." Lantek will translate your visual nest into a text-based G-code file specific to your machine's controller (such as Fanuc, Siemens, or Mazak). Final Tips for Efficiency
Save Remnants: If a job doesn't use a full sheet, use the "Save Remnant" feature. Lantek will catalog the leftover shape so you can nest smaller parts onto it later.
Update Tables: Regularly update your technology tables (feed rates and power settings) based on real-world results from your machine operator.
Use Layers: Keep your drawing clean by using different layers for marking/etching versus actual cutting.
By following this Lantek Expert tutorial, you can transform a raw DXF file into a precision-cut metal component with minimal material loss and maximum machine uptime.
Lantek Expert is a high-end CAD/CAM nesting software designed to automate the CNC programming of sheet metal machines, including laser, plasma, oxy-fuel, water jet, and punching technologies. 1. Getting Started: Basic Configuration
Before processing parts, you must set up your working environment to ensure data is organized and machine settings are accurate.
Database Creation: Your first step is creating a database to store all parts, sheets, and manufacturing orders.
Folder & Order Management: Use Folders to organize data by major projects or customers. Use Orders to group parts for specific production runs; once an order is finalized, it prevents accidental overwriting of parts.
Interface Overview: The software operates across three main screens: Remember: Always run a dry run (air cut)
Main Screen: For managing folders, orders, and permanent machine settings. Drawing Screen: For creating or verifying 2D part geometry.
Nesting & Machining Screen: For arranging parts on sheets and generating CNC code. 2. Part Preparation & CAD Importing
Intelligent Import: You can import drawings from major CAD systems like SolidWorks, Autodesk Inventor, and Solid Edge.
Drawing Verification: Always check for "problematic elements" (gaps or overlapping lines) in the Drawing Screen before proceeding, as these can cause errors during cutting.
Parametric Library: For standard shapes, use the built-in library of parametric parts to quickly generate geometry without external CAD files. 3. Nesting Strategies
Nesting optimizes material usage by fitting as many parts as possible onto a single sheet.
Automatic Nesting: The system automatically arranges parts based on your material and thickness settings.
Manual & Semi-Automatic: You can manually move, rotate, or copy parts to fill specific gaps or prioritize larger components first.
Remnant Management: Lantek automatically detects leftover material (remnants) in your warehouse and prioritizes using them before starting a new sheet. 4. Applying Technology & Machining Lantek Expert CAD/CAM Nesting Software
Lantek Expert is a powerhouse in the sheet metal industry, widely used for CAD/CAM nesting to automate CNC programming for laser, plasma, waterjet, and punching machines.
Below is a structured guide to getting started with Lantek Expert, covering everything from initial setup to final nesting. Getting Started with Lantek Expert 1. Understanding the Workspace
Before diving into production, familiarize yourself with the core modules:
Job Explorer: The "brain" of your projects. It uses a tree-like folder structure to organize your parts, materials, and sub-jobs.
Drawing Module: While you can import external files, Lantek includes a full CAD system for creating geometry from scratch or "cleaning up" messy third-party DXF/DWG files. 2. The Core Workflow (Step-by-Step) Most users follow this standard "Job-to-Nest" sequence: Description 1 Create a Job Lantek Expert is a powerful CAD/CAM/Nesting software suite
Open Job Explorer and start a new job. Define the customer, material type, and sheet thickness. 2 Import or Draw
Import your DXF/DWG files. If they contain "loose" lines or extra layers, use the drawing module to clean the contours. 3 Apply Machining
Set your lead-ins, lead-outs, and micro-joints. Advanced versions (2022+) feature Automatic Micro Joint Configuration for faster processing. 4 Nesting
Arrange parts on the sheet. You can use Automatic Nesting for speed or Manual Nesting for prototypes and high-material-value jobs. 5 CNC Generation
Once satisfied with the layout, generate the CNC code (Post-Processing) specific to your machine (e.g., Trumpf, Amada, Mazak). 3. Advanced Productivity Features Sheet Happens I: How to use Lantek Job Explorer effectively
