CNC Simulator Pro — Watch Your G-code Cut Metal in the Browser, for Free

Description and use

CNC Simulator Pro is a free, browser‑based 3‑axis milling simulator that lets users see 3D material removal in real time, ideal for CNC education.

Problem

Industrial CNC simulators cost thousands and free tools are limited to 2D or require heavy installation, leaving students unable to see 3D machining in real time.

Outcome

The simulator offers a free, install‑free, browser‑based environment that accurately visualizes 3‑axis milling, enabling learners to practice CNC programming safely and realistically.

Workflow

• 1. Open https://rudra496.github.io/cnc/ in a browser. 2. Load a G‑code file or select an example program. 3. Observe real‑time 3D machining with Three.js rendering. 4. Use the DRO control bar to monitor live position. 5. Adjust feeds and speeds via the calculator for realistic parameters. 6. Explore tool and material libraries to set up realistic machining scenarios.

Evidence

CNC education is stuck: industrial simulators cost thousands, and free tools are either 2D toys or install‑heavy desktop software.

Source

CNC Simulator Pro is exactly that: a free, open‑source, professional‑grade 3‑axis milling simulator that runs 100% client‑side.
