Machining. Machining is manufacturing process that involves removing materials using cutting tools for getting rid of the unwanted materials from some workpiece and converting it into the shape you desire. A large piece of stock is used for cutting the workpiece. The large stock might be in any shape such as solid bar, flat sheet, beam or even hollow tubes.
