What type of machine typically uses G-code for operation?

CNC machines use G-code for operation, which stands for "Geometric Code." This code is a language that instructs the CNC controller on how to move the machine's components. G-code commands dictate the movement of the cutting tool (including its speed, feed rate, and path) and are essential for automating machining processes. This automation allows for precise and repeatable manufacturing, making CNC machines suitable for complex tasks that require high accuracy.

In contrast, manual mills, band saws, and drill presses do not require G-code for operation. Manual mills are operated by human operators who control the machine directly, requiring no programming. Band saws and drill presses also do not utilize G-code, as they are typically set up for specific tasks without the need for computer programming. This distinction highlights the technological advancement and efficiency offered by CNC machines as compared to traditional machining methods.
