No, not all CNC machines use the exact same programming language, though G-code (also known as RS-274) is the de facto industry standard and the most widely used across mills, lathes, routers, and other types. Variations in G-code dialects—specific to manufacturers, controllers (e.g., Fanuc vs. Haas), or machine types—mean that the same program might need tweaks for compatibility, such as differences in coordinate systems, canned cycles, or auxiliary commands. Some machines also incorporate M-codes (for miscellaneous functions like coolant control) alongside G-code, but these follow similar standardization with local flavors.

Proprietary or Alternate Languages: Certain specialized machines, like Swiss-style lathes or older controls, use custom languages instead of pure G-code. Conversational programming interfaces (e.g., wizard-style software) on some modern machines bypass G-code entirely, generating it automatically in the background.

Hybrid Approaches: Many CNCs support multiple input methods, including G-code, but may default to CAM-generated code from software like Fusion 360 or Mastercam, which outputs machine-specific variants.

In practice, portability issues are common when moving programs between machines, so always verify compatibility via simulation or testing. As of 2025, standardization efforts continue, but full uniformity remains elusive due to legacy systems and innovation.
