Industrial NC Program Verification.

Verify your actual CNC programs on a perfect digital twin.
Catch collisions, gouges, and logic errors before you cut metal.

What is NC program verification? It is specialized software that interprets the actual NC program—the post-processed G-code—and executes it on a virtual machine model to catch collisions and errors before machining. With Eureka3X, your CNC machine simulator serves as a perfect digital twin for rigorous NC program verification.

Trusted by professionals who can't afford mistakes

Eureka3X is built on Eureka Virtual Machining — 20+ years of industrial CNC simulation, used in production by world-class manufacturers.

Sound familiar?

These happen every week in every shop. Eureka3X fixes all three.

THE PROBLEM

Post-processor bugs and errors

CAM simulation shows a perfect part, but the post-processor generates an unexpected retract or incorrect cycle parameter.

THE FIX

Verify the actual CNC program

Eureka3X simulates the exact G-code that goes to the machine, catching post-processor issues before they hit the controller.

THE PROBLEM

Setup and fixture collisions

Unexpected rapid moves (G0) into clamps, vises, or the machine table cost thousands in damage.

THE FIX

Full digital twin simulation

We simulate the entire machine kinematics, including your specific fixtures and tools, catching any physical interference.

THE PROBLEM

Machine-specific logic mistakes

Missing M-codes, incorrect work offsets (G54-G59), or tool length compensation errors (G43).

THE FIX

Controller-accurate emulation

Eureka3X emulates the exact logic of your specific controller (Fanuc, Haas, Heidenhain, Siemens), warning you of logical errors instantly.

Frequently Asked Questions

+What is NC program verification?

It is the process of simulating the actual post-processed CNC code to ensure it is collision-free and runs correctly on the real machine.

+Why can't I just use CAM simulation?

CAM simulation verifies the toolpath before post-processing. NC program verification verifies the exact G-code the machine will read, catching post-processor errors and machine-specific logic.

+Which machines are supported?

Eureka3X includes ready-to-use digital twins for Fanuc, Haas, Siemens, and Heidenhain machines out of the box.

+Can I load my own tools and fixtures?

Yes, Eureka3X allows you to import your exact tooling, fixtures, and stock to simulate the real-world setup perfectly.
