CNC machine pouring coolant to keep the tool and parts from getting hot Lathe machine. 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.
Schematic of ultrasonic machining process An ultrasonic drill from 1955. Ultrasonic machining is a subtractive manufacturing process that removes material from the surface of a part through high frequency, low amplitude vibrations of a tool against the material surface in the presence of fine abrasive particles.
A 3-axis clone of a Bridgeport-style vertical milling machine. Milling is the process of machining using rotary cutters to remove material [1] by advancing a cutter into a workpiece.
Bessemer converter, schematic diagram. The Bessemer process was the first inexpensive industrial process for the mass production of steel from molten pig iron before the development of the open hearth furnace.
Microfabrication technologies originate from the microelectronics industry, and the devices are usually made on silicon wafers even though glass, plastics and many other substrate are in use.
Mechanical problems in early satellites were sometimes attributed to cold welding.. In 2009 the European Space Agency published a peer reviewed paper detailing why cold welding is a significant issue that spacecraft designers need to carefully consider. [3]
Forging a nail. Valašské muzeum v přírodě, Czech Republic. Forging is one of the oldest known metalworking processes. [1] Traditionally, forging was performed by a smith using hammer and anvil, though introducing water power to the production and working of iron in the 12th century allowed the use of large trip hammers or power hammers that increased the amount and size of iron that could ...
Brazing practice. Brazing is a metal-joining process in which two or more metal items are joined by melting and flowing a filler metal into the joint, with the filler metal having a lower melting point than the adjoining metal.
