CNC machining milling is a subtractive manufacturing process that uses computer-controlled cutting bits, which spin, to trim e\u00d7cess material away from the workpiece. That technology yields precision components that, after processing, can be the tiny part of a complex aerospace assembly or medical device. Read about each aspect of the milling workflow – types of machinery, machining processes, ISO 2768 tolerance specifications, material options and validated cost standards – before a quote Request shows up for the programmer\/machinist.<\/p>\n

What Is CNC Machining Milling?<\/h2>\n

\"What<\/p>\n

CNC milling is a Computer Numerical Control (CNC) machining operation that uses a CNC machine with a rotating cutter moving along multiple axes to achieve precise material removal from a workpiece and create the target shape. While drilling involves pushing a single-point cutting tool along a single axis, CNC milling cutters can engage with a workpiece at a multitude of angles, producing pockets, slots, bores, contoured surfaces, and intricate designs within tighter tolerances on a single fixture.<\/p>\n

The computer numerical control is basically a G-code program that tells the spindle how fast to turn; the table or tool how fast to traverse; the direction of travel; and when to kick in the coolant. Work is chucked to a workholding surface (the machine table) or the tool is mounted into the spindle: it rapidly rotates to cut away material. The axis movements are servo-controlled (often by stepping motors as well), driving the work piece and cutting tool along the exact path designated.<\/p>\n

To the thousandth (or whatever the programmed tolerance dictates), it should produce a part exactly like the computer design.<\/p>\n
