Machining is a manufacturing process where a desired shape or part is created using the controlled removal of material, most often metal, from a larger piece of raw material by cutting. Machining is a form of subtractive manufacturing , [ 1 ] which utilizes machine tools , in contrast to additive manufacturing (e.g. 3D printing ), which uses ...
He is one of the founding members of Machining Science and Technology Journal and serves as a member of the editorial boards of five other scientific journals. He is a Fellow of ASME (American Society of Mechanical Engineers), ASM International(American Society for Metals), SEM ( Society for Experimental Mechanics ), SME (Society of ...
Laser machining is a traditional technique that uses nanosecond pulses of ultraviolet light to create mesoscale features like holes, fillets, etc. The removal of material during laser machining is proportional to exposure time and therefore this process can be used to create three dimensional features.
Multiaxis machining is a manufacturing process that involves tools that move in 4 or more directions and are used to manufacture parts out of metal or other materials by milling away excess material, by water jet cutting or by laser cutting. This type of machining was originally performed mechanically on large complex machines.
Electrical discharge machining is a machining method primarily used for hard metals or those that would be very difficult to machine with traditional techniques. EDM typically works with materials that are electrically conductive, although methods have also been proposed for using EDM to machine insulating ceramics.
CAD model and CNC machined part. Computer-aided manufacturing (CAM) also known as computer-aided modeling or computer-aided machining [1] [2] [3] is the use of software to control machine tools in the manufacturing of work pieces.
A part's-eye view of a boring bar. Hole types: Blind hole (left), through hole (middle), interrupted hole (right). In machining, boring is the process of enlarging a hole that has already been drilled (or cast) by means of a single-point cutting tool (or of a boring head containing several such tools), such as in boring a gun barrel or an engine cylinder.
Erosion technologies: by water jet, electric discharge, or abrasive flow machining. Chemical technologies: Photochemical machining; Cutting fluid or coolant is used where there is significant friction and heat at the cutting interface between a cutter such as a drill or an end mill and the workpiece. Coolant is generally introduced by a spray ...
