What is CNC Milling?
CNC milling machines are automated cutting machines that use a rotating spindle head to cut away unwanted material. CNC milling machines come in a variety of sizes and with different axis configurations. This manufacturing process is primarily used to cut harder metals, but can also process workpiece materials ranging from plastics and aluminum to stainless steel and titanium.
CNC milling machines excel at cutting harder materials. Like all CNC machines, CNC milling machines are controlled through G-Code created by CAM software. The G-Code instructs the machine where to move the tool head, how fast to spin the tool, how deep to cut, how to move the workpiece, and other factors related to speed, feed rate, and coordination. The complexity of the G-Code depends on how many axes the milling machine has.
