What does CNC mean?
CNC stands for computer numerical control, representing a sophisticated manufacturing process that employs software to oversee the operations of various CNC machines. Simply put, a CNC machine refers to any machine integrated with CNC technology and functionalities.
This technology enables machinists and skilled professionals to utilize mechanical design, drawings, mathematics, and computer programming expertise to fabricate precise parts. With CNC programming and operation, a metal workpiece can be transformed into a crucial component for aerospace or automotive applications with unparalleled accuracy. Contemporary machines often consolidate multiple tools into one, enhancing the efficiency of the CNC machining process.
What does a CNC machine do?
The main purpose of CNC is to manage the movements of a machine tool. Digitized data, a computer, and a computer-aided manufacturing (CAM) program collaborate to oversee, automate, and supervise the actions of the CNC tools. In extensive industrial machines, an integrated computer serves as a dedicated onboard controller, whereas smaller hobbyist models rely on an external computer.
Every CNC controller collaborates with multiple motors and drive components to carry out and regulate the programmed motions. In advanced machines, a feedback system consistently monitors and fine-tunes the cutter’s speed, feed rate, and position.
What is an example of a CNC machine tool?
The milling machine stands out as perhaps the most widely recognized example of a CNC machine tool. However, numerous others exist, including lathes, electric discharge machines (EDM), grinders, laser cutters, plasma cutters, waterjet cutters, CNC routers, and 3D printers. While the CNC machining process may differ to some extent for each of these, the fundamental principles of the machining process remain consistent across all.
CNC machines are also available in various sizes, ranging from compact desktop CNC machines like tabletop mills or benchtop routers to robust, large horizontal machining centers. Let’s delve into each of these machines individually to explore their distinctive features.
