Machining techniques are processes used to shape and finish materials, primarily metals and plastics, into desired forms. Common methods include turning, milling, and drilling, each utilizing specialized tools to remove material. These techniques are essential in manufacturing industries for producing precise components. In addition to traditional methods, advanced machining techniques like CNC machining and 3D printing have emerged. CNC machining uses computer-controlled tools for high accuracy, while 3D printing builds objects layer by layer from digital models. Both approaches enhance efficiency and allow for complex designs that were previously difficult to achieve.
