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:
“The axioms of physics translate the laws of ethics. Thus, “the whole is greater than its part;” “reaction is equal to action;” “the smallest weight may be made to lift the greatest, the difference of weight being compensated by time;” and many the like propositions, which have an ethical as well as physical sense. These propositions have a much more extensive and universal sense when applied to human life, than when confined to technical use.”
—Ralph Waldo Emerson (1803–1882)
“It has become a people’s war, and peoples of all sorts and races, of every degree of power and variety of fortune, are involved in its sweeping processes of change and settlement.”
—Woodrow Wilson (1856–1924)
