Lantek Expert is a premier CAD/CAM nesting software designed specifically for automating the CNC programming of sheet metal cutting machines (laser, plasma, oxy-cut, waterjet, and punch).
This write-up covers the essential workflow for a standard project, from importing geometry to generating the final CNC code. 1. Job Setup and Material Selection
The process begins by defining the environment for the specific task. Create a New Job: Open the Lantek Expert explorer and start a new project. Material and Thickness:
Select the appropriate material (e.g., Stainless Steel, Aluminum) and thickness from the database. This ensures the software applies the correct cutting technology tables, such as feed rates and lead-ins. Machine Selection: Choose the specific CNC machine you will be using. 2. Importing and Preparing Parts
Parts can be drawn directly within Lantek or imported from external CAD files. Importing Geometry: Lantek Import tool to bring in DXF, DWG, or IGES files. Cleaning Geometry:
Ensure all contours are closed. The software often includes a "Clean" function to remove duplicate lines or small gaps that could cause errors during machining. Defining Quantities:
Assign the number of units required for each part within the "Part Data" window. 3. Machining (Toolpath Generation) Before nesting, the software needs to know to cut each individual part. Automatic Machining:
For most standard parts, use the "Automatic Machining" feature. It automatically assigns lead-ins/lead-outs and cutting directions based on your machine's technology tables. Manual Machining:
If a part has complex internal cutouts or requires micro-joints (tabs) to keep it from falling through the slats, you can manually place these elements using the Manual Machining 4. Nesting Optimization
Nesting is the process of arranging parts on a sheet to minimize scrap. Automatic Nesting:
Lantek’s algorithm calculates the most efficient layout. You can define parameters like part rotation (e.g., 90° or 180° increments) and the distance between parts. Manual Adjustments:
You can drag and drop parts to fill gaps or use "Common Line Cutting" to share a single cut between two adjacent parts, saving time and gas. Remnant Management: If a sheet is not fully used, Lantek can create a remnant
, saving the leftover geometry back into the library for future jobs. 5. Simulation and G-Code Generation
The final step is verifying the sequence and exporting the instructions for the machine. Simulation:
Run the 2D/3D simulation to watch the cutting head's path. Check for potential collisions or inefficient rapid movements between cuts. Post-Processing: lantek expert tutorial
Once satisfied, click "CNC Generation." The software translates the visual layout into the specific G-code language (e.g., ESSI, ISO) required by your machine controller.
Generate a "Nesting Report" for the machine operator, which typically includes a visual map of the sheet, a list of parts, and estimated cutting time. Punching-specific AI responses may include mistakes. Learn more
A compelling feature for a Lantek Expert tutorial should focus on Nesting Optimization and Automation
, as this is a core strength of the software that directly impacts production efficiency.
Below are several specific feature ideas for a tutorial, categorized by skill level: 1. Advanced Nesting & Material Optimization
This is often the most sought-after topic because it relates directly to reducing scrap and costs. Automatic vs. Manual Nesting Strategies : A deep dive into the Lantek Expert Cut
module to show how to balance fully automatic algorithms with manual "fine-tuning" like rotating or moving parts for maximum plate utilization. Common Line Cutting

Lantek Expert Tutorial: A Comprehensive Guide to Mastering CAD/CAM for Sheet Metal
Lantek Expert is a world-leading CAD/CAM nesting software specifically designed to automate the CNC programming of sheet metal cutting and punching machines. Whether you are working with laser, plasma, oxy-fuel, water jet, or punching technology, this tutorial provides a structured path from basic setup to advanced optimization. 1. Getting Started: Basic Configuration
Before you begin designing or nesting, you must configure the software environment to match your workshop's workflow. Lantek Expert is a premier CAD/CAM nesting software
Database and Installation: Your first step is to create a database to store all your projects, parts, and machine data.
The Interface: Lantek operates across three primary screens:
Main Screen: Used for general management, creating folders (for projects), and setting permanent machine configurations.
Drawing Screen: Dedicated to creating, importing, and verifying 2D geometry.
Nesting and Machining Screen: Where you arrange parts on sheets and generate the CNC code.
Organizing Work: Use Folders for major projects or customer data and Orders to manage specific batches of parts.
Tip: Avoid using special characters like "@" or "%" in order names to prevent Windows file system errors. 2. The Drawing Module: Design and Import
Lantek Expert features a powerful 2D CAD module built specifically for plate part design.
Importing Files: You can import standard formats like DXF, DWG, IGES, and DSTV.
Part Verification: After importing, always use the Part Verifier tool. It automatically identifies and highlights geometric errors that could cause machining failures.
Design Tools: The "Start" menu contains standard CAD tools such as "Draw," "Modify," and "Transform".
3D Integration: For complex designs, Lantek can automatically unfold 3D models from software like SolidWorks, Autodesk Inventor, and Solid Edge. 3. Mastering Nesting: Maximizing Material Yield
Nesting is the process of arranging parts on a metal sheet to minimize scrap. 1. Basic1 screen configuration of LANTEK
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 Step 1: Importing Your Part Design
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:
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
In modern fabrication, most parts arrive as DXF or DWG files. The tutorial covers the Import Wizard, which automates the cleaning of "dirty geometry" (overlapping lines, open corners) often found in customer CAD files.
