About this app

Transform your smartphone into a powerful CNC programming tool with the CNC G-Code Simulator!

Whether you are a professional CNC machinist, a programmer, or a student learning the trade, this app is the ultimate companion for visualizing, generating, and converting G-codes on the go.

🛠️ POWERFUL 2D & 3D VISUALIZATION
Never guess what your toolpath will look like. Input your external or internal contour G-codes and instantly visualize the machining process.
• 2D View: Clean and precise cross-section verification.
• 3D Spatial View: Rotate, pan, and zoom to inspect your workpiece from every angle.
• Customizable Stock Dimensions: Adjust the raw diameter and length to match your real-world material.

📂 EFFICIENT FILE MANAGEMENT: IMPORT & EXPORT
Work smarter wherever you are:
• Program Import: Load your existing G-code files (.prg, .txt, .arc) directly into the editor and pick up exactly where you left off.
• TXT Export: Save your generated toolpath or G-code with a single tap. Share it as a file to your workshop or send it directly to your machine controller.

⚙️ ADVANCED G-CODE CROSS-COMPILER
Struggling with controller incompatibilities? Our built-in geometry engine automatically converts modern, angle-based G-codes into elemental X-Z coordinates.
• Resolves G01 A-angle linear movements using advanced trigonometry.
• Flawlessly handles complex geometries, including chamfers (,C, D, B-, CHR) and radiuses (G1 R).

🌍 MULTI-LANGUAGE SUPPORT
The app is available in 16 languages, allowing you to work comfortably in your native language anywhere in the world, ensuring technical terms are always clear and easy to understand.

🎛️ SUPPORTED CNC CONTROLLERS
Generate output code specifically formatted for your machine's language. Supported outputs include:
• Fanuc, Mitsubishi, Traub, Siemens D/C, and Point-to-Point modes.

🌟 FREE TRIAL & PRO UPGRADE
Try it for free for 14 days! Download the app and enjoy full access to G-code conversion, file management, and simulation features for two weeks with no strings attached.
