CNC Machining Processes and Technologies Overview
What are the Different Processes of CNC Machining?
The requirements for a particular design can be achieved using different methods of machining processes. These are: CNC milling, CNC turning, CNC grinding, and electrical discharge machining (EDM). During CNC milling, a workpiece with varying dimensions and surface finishes is achieved through the removal of materials by rotary cutting tools. In CNC turning, the workpiece is rotated, and a cutting tool is used to shape the workpiece, which is ideal for cylindrical workpieces. Ultra-smooth surfaces and precise dimensional accuracy are produced using abrasive tools in CNC grinding. This technique is often utilized for finishing work. EDM creates intricate shapes in hard materials by using electrical discharges to erode the material. Different geometric shapes and distinct CNC machines are used for each of the machining processes to achieve specific features and characteristics.
In What Aspects CNC Turnning and CNC Milling are the Same or Related?
CNC milling and CNC turning differ in gewometric shape being machined but the differences are mainly in methods of cutting as well as the ranges of products applicable. In CNC milling, multi-point rotary tools are positioned above the workpiece to remove material; this process can create parts with complex geometries. Moreover, the capabilities of a milling machine allows operations on flat surfaces, contour or irregular surfaces, and very intricate pieces detailing.
Instead, CNC turning attaches the workpiece to a rotating spindle which turns while a stationary cutting tool moves linearly toward and away from the workpiece. This method is ideal for manufacturing cylindrical or symmetrically shaped features like shafts and other cylindrical elements. Both approaches require accuracy and a high degree of automation, and determining whether to use CNC milling or turning is based on the geometry and fabrication needs of the part.
