Physical Processes
There are several physical processes for reshaping a material by cutting, folding, joining or polishing, developed on a large scale from workshop techniques.
See also: Fabrication (metal)- Forging - the shaping of metal by use of heat and hammer
- Casting - shaping of a liquid material by pouring it into moulds and letting it solidify
- Machining - the mechanical cutting and shaping of metal
- Progressive stamping - the production of components from a strip or roll
- Hydroforming - a tube of metal is expanded into a mould under pressure
- Sandblasting - cleaning of a surface using sand or other particles
- Soldering, Brazing, Welding - a process for joining metals
- Tumble polishing - for polishing
- Precipitation hardening - heat treatment used to strengthen malleable materials
- Work hardening - adding strength to metals, alloys, etc.
- Case hardening, Differential hardening, Shot peening - creating a wear resistant surface
- Die cutting - A "forme" or "die" is pressed onto a flat material in order to cut, score, punch and otherwise shape the material
- Machining- the process of giving desired shape which involves the loss of material. Examples: planing, shaping, milling, punching, drilling, grinding

Famous quotes containing the words physical and/or processes:
“Women are to be lifted up to a physical equality with man by placing upon their shoulders equal burdens of labor, equal responsibilities of state-craft; they are to be brought down from their altruistic heights by being released from all obligations of purity, loyalty, self-sacrifice, and made free of the world of passion and self-indulgence, after the model set them by men of low and materialistic ideals.”
—Caroline Fairfield Corbin (b. c. 1835–?)
“The vast results obtained by Science are won by no mystical faculties, by no mental processes other than those which are practiced by every one of us, in the humblest and meanest affairs of life. A detective policeman discovers a burglar from the marks made by his shoe, by a mental process identical with that by which Cuvier restored the extinct animals of Montmartre from fragments of their bones.”
—Thomas Henry Huxley (1825–95)
