Basic overview of machining types
Processing type
All "manufacturing" is inseparable from "processing". Completing a product involves a variety of processes, from the manufacturing of parts and machines to consumer goods. In this sense, processing can be said to be the basis of manufacturing. With the advancement of technology, various processing methods have emerged, but they can be divided into several categories. But in reality, these types of machining are difficult to draw a line between, and each machining method has parts that are common to other machining or parts that are intricately intertwined with each other, so this is just a matter of convenience.
Processing that changes the shape of an object by applying force: polishing, grinding, cutting, pressing (bending, shearing, drawing), drawing, extrusion, rolling, forging;
Processing by heating: heat treatment, casting, welding, sintering, fusion;
Processing using electrical or chemical power: electrical discharge machining, electroplating, electropolishing, laser processing, electron beam processing, electrodeposition, electroforming;
Processing that applies force includes processing using blades such as grinding, cutting, and cutting, and processing that applies pressure to cause deformation such as pressing and rolling. Polishing is considered a complex process as it involves not only cutting aspects but also chemical elements such as CMP. Processes that apply heat include heat treatments that change the hardness and mechanical properties of the metal, welding, fusion, casting (which involves pouring molten metal into a mold and allowing it to solidify), and sintering (which involves baking and solidifying the powder). Recently, various electrical and chemical processing methods have been put into practical application, including electrical discharge machining and laser processing, as well as surface treatment techniques such as electroplating, thermal spraying, sputtering, CVD and vapor deposition to apply thin films. Formation can also be added.
