Lantek Expert Tutorial Fixed May 2026

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:

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 comprehensive CAD/CAM system specifically designed for sheet metal manufacturing, automating the programming of CNC cutting (laser, plasma, oxy-fuel, waterjet) and punching machines. 1. Basic Configuration and Workspace

Before starting production, you must set up the database and environment:

Database Setup: Create your first database to store materials, machines, and customer data.

Job Explorer: Use the Job Explorer (located on the left side by default) to create folders for major projects or specific customers. lantek expert tutorial

System Configuration: Access the Manage tab to configure machines, system units (e.g., mm or inches), and material-specific data like thickness-dependent parameters. 2. Importing and Drawing Parts

Lantek allows you to bring in geometry or create it from scratch:

File Import: You can import standard CAD files such as DXF or DWG.

Assigning Attributes: Use specific colors to define tool paths. For example, light green often represents cutting, while yellow indicates marking (for bending lines or part numbers).

Text Management: Use "Mark Text" for serial numbers or "Aptext" for specialized cutting/marking fonts. 3. Nesting Strategies

Nesting optimizes material usage by placing as many parts as possible on a single sheet:

Automatic Nesting: The software can automatically arrange parts based on priority and due dates.

Manual Adjustments: Use manual tools like grid copying, rotating, and moving to fine-tune placement where automatic algorithms might leave gaps.

Remnant Management: You can define remnants (leftover material) to be used in future jobs. 4. Machining and Technology Settings

This step defines how the machine physically cuts the parts: 1. Basic1 screen configuration of LANTEK

This guide provides a structured walkthrough for Lantek Expert, the industry-standard CAD/CAM system designed for automating the CNC programming of sheet metal cutting machines (laser, plasma, oxy-fuel, and waterjet). 1. Project Setup and Database Management

Before drawing or nesting, you must define your environment. Lantek operates on a database-driven logic where "Jobs" organize your work.

Create a New Job: Open the Explorer and create a new Job. This acts as a folder containing all parts, sheets, and nesting layouts for a specific project.

Material and Thickness: Select the correct material (e.g., Stainless Steel, Aluminum) and thickness from the database. This ensures the software applies the correct Technological Table (feed rates, gas pressures, and lead-ins).

Machine Selection: Assign the specific CNC machine you will be using. This loads the post-processor required to generate the final G-code. 2. Part Importing and CAD Preparation

Lantek Expert can create geometry internally or import external files. Importing DXF/DWG: Go to Import and select your CAD files.

Cleanup: Use the "Automatic Clean" tool to remove duplicate lines, open contours, or tiny fragments that cause CNC errors. Lantek Expert is a high-end CAD/CAM nesting software

Layer Mapping: Ensure the geometry is on the "Cutting" layer and any etching/marking is on the "Marking" layer.

Defining Part Properties: Assign a name, quantity, and priority to each part. You can also define "Grain Direction" if the part must be oriented a certain way relative to the sheet metal grain. 3. Nesting Strategies (The "Nesting" Module)

Nesting is where you arrange parts on a sheet to minimize scrap.

Manual Nesting: Drag and drop parts onto the sheet. Use the mouse wheel to rotate parts or the "Arrow" keys for fine placement.

Automatic Nesting: Click Automatic Nesting. Lantek will run algorithms to find the tightest fit.

Tip: Use Grid Nesting for large quantities of the same rectangular part to save computation time.

Remnant Management: If you don't use a full sheet, Lantek can define a "Remnant" (scrap sheet) and save its irregular shape back into the library for future use. 4. Applying Toolpaths (The "Machining" Module) Once nested, you must tell the machine how to cut.

Lead-ins and Lead-outs: Configure the entry points. For thick materials, use a "circular" lead-in to prevent blowing a hole in the finished part.

Cutting Order: Use Automatic Machining to let the software determine the most efficient path. It typically follows a "Bottom-to-Top" or "Zig-Zag" logic to minimize head travel.

Micro-joints (Tabs): If parts are small and might tip over or fall through the slats, add micro-joints to keep them attached to the skeleton until the operator removes them.

Common Line Cutting: For rectangular parts placed side-by-side, use common line cutting to share a single cut path, reducing time and gas consumption. 5. Simulation and G-Code Generation Always verify your work before sending it to the machine.

CNC Simulation: Watch the 2D animation of the cutting head. Check for potential collisions or inefficient movements.

Generating the CNC File: Click G-Code (or "CNC"). The software translates the visual layout into the specific language of your machine (e.g., Fanuc, Siemens, Mazak).

Workshop Reports: Print the "Nesting Report." This provides the machine operator with a visual map of the sheet, the list of parts, and the estimated cutting time. Troubleshooting Quick-Tips

"Open Contours" Error: Use the Verify -> Open Contours tool to find gaps in your geometry that prevent toolpath generation.

Nesting Overlap: Ensure your "Part-to-Part" and "Part-to-Edge" distances are set correctly in the Machine Configuration to avoid cutting into adjacent parts.

Nesting best practices

  • Automatic nesting: good for high-volume/irregular shapes; enable common-line where beneficial.
  • Manual adjustments: lock critical parts, enforce spacing for heat dissipation, respect grain direction and material defects.
  • Nesting parameters: set sheet margin, part spacing, rotation limits, and minimal remnant size.
  • Common-line and skeleton nesting: use common-line for straight breaks to save material and reduce cutting time; use skeleton for progressive cutting on CNC punch/turret machines.

1. Drawing Tools

Lantek provides a robust 2D CAD engine.

  • Geometry Creation: Tutorials focus on standard shapes (lines, circles, rectangles) and specific sheet metal features like automatic corner radiusing and bridging.
  • Transformations: Users practice moving, rotating, and mirroring geometry.

7. Step 5 – Generate NC Code & Production Reports

Part 7: Simulation & Collision Detection

Never send code to the floor without simulating.

  • Click the 3D Simulation button (blue play icon).
  • Use the slider to watch the tool move.
  • Check for:
    • Rapid traverse crashes: Does the head drag across a tilted slug?
    • Pierce order: Is it piercing too close to a previously cut edge (which would heat warp the material)?

The "Red Zone" Warning: If Lantek highlights an area in red, it means Collision Detected. Go back to the Technology tab and increase the Micro-joint distance or change the Part exit point.
