GetGCode is a free online G-code simulator and editor for CNC lathes and mills, built by a senior CNC setter who works in aerospace machining. Paste or upload your program and see the toolpath in 2D/3D, step through it line by line, catch mistakes before they reach the machine and get a realistic cycle time. It works in the browser, with nothing to install. Around the simulator, GetGCode brings the references a CNC shop checks every day: • Thread charts and tap drill sizes: metric, UNC/UNF, NPT, BSP and Helicoil • Cutting speed, RPM and feed calculators by material and operation • G and M codes with syntax for Fanuc, Haas, Siemens and Heidenhain • CNC alarm guide, ISO 286 fits and GD&T symbols GetGCode Pro adds AI: upload a drawing and get a G-code program to review and simulate, plus a process assistant for programming and machining questions. Available in English and Spanish.
