Fabrication technology, concept of production engineering and mechanical engineering, is the study of the economic production of formed work pieces from given starting materials according to given geometric determinants ( subject to certain tolerances) and their assembly into functional products. A product can be a final product or a semifinished product, for example in the form of an assembly. The basic concepts of manufacturing processes are summarized in DIN 8580. Working field of manufacturing technology is developing, further development and application of manufacturing processes.
The production technology influences the conversion of a workpiece from the raw state to the state of production. In this respect, its history is as old as mankind. However, only since the beginning of the industrial revolution in the mid 18th century, the manufacturing technique was developed using scientific methods.
Johann Beckmann founded the general technological science. He introduced the concept of technology already 1769. Frederick Winslow Taylor in 1900 used the term management science and reasoned Taylorism. Henry Ford continued with the Production Line of typing and mass production. The production technology is part of the production research (see also: Industrial Engineering ).
Basic concepts of manufacturing technology are in accordance with DIN 8580:
- Production methods: Method for producing geometrically defined solid body
- Workpiece: item of a technical fabric in the manufacturing
- Active medium: Formless, solid, liquid or gaseous substance which causes through various forms of energy, as well as by chemical reactions changes on the workpiece.
- Action pair: Made out of workpieces on the one hand and tool or action medium / media on the other hand
- Archetypes: A solid body of formless substance (liquid, powdery raw material or plastic mass ) created by producing the cohesion eg by casting, sintering, calcining or baking.
- Forming: Forming the Customize by image- Sames ( plastic ) Changing the shape of a body, without the amount of material is changed, eg by bending, pulling, pressing, pushing or rolling.
- Add: The introduction of previously separate workpieces in a fixed connection at designated joints, such as by welding, soldering or gluing.
- Disconnect: Changing the form of a solid body in which the cohesion is released locally, eg by cutting, machining or machining.
