Which G code is used to identify linear interpolation (feed in a straight line)?

The G code used to identify linear interpolation, which allows for feed in a straight line from one point to another, is G01. This command instructs the CNC machine to move the tool in a straight line at a specified feed rate, providing precise control over the movement during machining operations.

In contrast, G00 is used for rapid positioning, moving the tool quickly without concern for the feed rate. G02 and G03 codes are utilized for circular interpolation, where G02 denotes a clockwise arc and G03 denotes a counterclockwise arc. Understanding these distinctions is crucial for effective programming and operation of CNC machinery, as each G code serves a specific purpose in the machining process.
