What Is CNC Milling?

Computer Numerical Control (CNC) milling uses commands or G-codes to program machinery. Each alphanumeric code has a designated function to be performed by the machine. The mills drill and turn along axes to cut and shape metal and wood. CNC milling machines create graphic, logo and web designs. The process can be used with router, lathe, laser and foam cutter machines.

 Computer Numerical Control Milling
Milling is a cutting operation with a geometrically specified cutting edge in which the tool makes the rotating main movement, and the feed as well as the in feed movement are generally made by the work part.
Milling operations are classified according to the position of the position of the milling axis towards the work part, i.e. between face milling and peripheral milling. In case of face milling, the milling axis is located vertically to the machining.

Milling (machining) – Wikipedia, the free encyclopedia

CNC machines can exist in virtually any of the forms of manual machinery, like horizontal mills. The most advanced CNC milling-machines, the multi-axis machine, add two more axes in addition to the three normal axes (XYZ). Horizontal milling machines also have a C or Q axis, allowing the horizontally mounted workpiece to be rotated, essentially allowing asymmetric and eccentric turning.

 Cnc Machining Handbook: Basic Theory, Production Data, and Machining Procedure

James Madison, published 1996, 380 pages

This all new handbook is the most comprehensive and authoritative reference available on CNC machining centers and their capabilities, commonly used CNC commands, and CNC related tooling for the production of precision machined components. Written for programmers, engineers, and operators, it provides a ready reference for basic theory, production data, and machining procedure. Both apprentices and experienced operators and programmers will find this invaluable reference an essential source for all their needs.
