Gコード(正式名称はRS-274)は最も普及している プログラミング言語 for controlling CNC machines. It consists of sequential commands that instruct the machine on positioning, speed, and specific actions. Commands begin with a letter address; ‘G’ denotes preparatory commands for motion (e.g., G01 for linear feed), while ‘M’ signifies miscellaneous functions (e.g., M03 for spindle start). G-code is an engineering programming language in its own right, aimed at machine tools rather than general computing.
