Machining is a process that shapes a desired product or part by removing material from a larger piece using power-driven tools for cutting, grinding, or chipping. It's a form of subtractive manufacturing, where the desired shape is created by removing unwanted material instead of adding it. 


Typical machining process includes but not limited to the following:


Turning:

Using a lathe to rotate the workpiece while a cutting tool removes material to create cylindrical shapes. 


Milling:

Using a milling machine with a rotating cutter to remove material and create complex shapes. 


Drilling:

Using a drill bit to create holes in the workpiece. 


Grinding:

Using a rotating abrasive wheel to remove material and achieve precise finishes. 


Also tapping, knurling, and so on.


In essence, machining is a fundamental manufacturing process for creating parts with precise shapes and dimensions by removing material from a larger piece, often using specialized machines and tools like lathes, mills, and grinders.
