Snet Machining is any of various processes in which a piece of raw material is cut into a desired final shape and size by a controlled materialremoval process. The processes that have this common theme, controlled material removal, are today collectively known as subtractive manufacturing, in distinction from processes of controlled material addition, which are known as additive manufacturing.

Milling is the most common form of machining, a material removal process, which can create a variety of features on a part by cutting away the unwanted material. The milling process requires a milling machine, workpiece, fixture, and cutter. The workpiece is a piece of preshaped material that is secured to the fixture, which itself is attached ...
Sep 21, 2005· A surface machining process, such as conventional grinding and lapping, introduces damages into ground surface layers of ceramic materials [1012]. Excessive forces during the grinding process generate defects such as chips, cracks, flaws, and/or fissures. The grinding defects decrease the strength of ceramics [13, 14].

WET GRINDING. The raw materials are taken in a ball mill and them grinded with water for certain hours. The grinding media is usually alumina because it has good wear resistance and good density. This process is known as wet grinding. The raw material will be obtained in a slurry form at the end of the wet grinding process.
