What are areas for production engineering

Production engineering

1. Term: Transformation of scientific knowledge into procedures and processes that are technologically controllable by humans and can be integrated into economically usable production systems.

2. Species: The field of production technology can be subdivided into different sub-areas in relation to the type of service to be provided: a) Energy Technology: Generation, conversion and transmission of useful energy. The useful energy is divided into thermal energy for space heating and hot water, energy for carrying out industrial production processes, and drive and light energy.

b) Process technology: Techniques used in the production of fluid goods. Flowing goods are goods that are not macrogeometrically defined, such as bulk goods, liquids and gases. The production of such goods usually takes place in three Stages:
(1) Extraction of raw materials;
(2) Production of intermediate products;
(3) Production of final products. Within these three stages, one can basically differentiate between the processes of substance conversion and substance preparation:
(a) The procedures of Substance conversion are based on chemical and chemical-physical processes and include the analytical conversion of substances (e.g. hydrogen production by electrolysis), the synthetic substance conversion (e.g. gasoline synthesis), the analytical-synthetic substance conversion (e.g. pig iron production) as well as the substance reforming (change of the molecular structure).
(b) The procedures of Stock preparation are based on physical processes and include the separation (e.g. sorting, distillation), the mixing (e.g. alloying) and the structuring of substances (e.g. grinding).

c) Manufacturing engineering: Techniques used for the production of geometrically defined solid bodies (piece goods). As the central object of consideration in manufacturing technology, DIN 8580 distinguishes six main groups of manufacturing processes:
(1) Archetypes: The original molding processes cause certain bodies to be shaped; An individual part with complex geometry is created from a shapeless material, e.g. by casting or sintering.
(2) Forming: The forming techniques change the shape of the original body while maintaining the cohesion, e.g. extrusion, upsetting and folding.
(3) Separate: The shape of the original body is also changed when separating, but the cohesion is reduced, e.g. turning, grinding and unscrewing.
(4) Put: Joining processes, e.g. welding, soldering and gluing, increase cohesion and lead to a change in the shape of the original body.
(5) Coating: Coating is understood to mean the application of a firmly adhering layer to a workpiece. This allows various basic materials, e.g. metal, plastic and paper, to be refined (refinement). Coating processes are e.g. painting and electroplating.
(6) Change material property: The change in the properties of the material can take place once by rearranging material particles (e.g. magnetizing, hardening), whereby the cohesion is maintained. Furthermore, the material properties can also be changed by separating out material particles (e.g. decarburizing). The cohesion is reduced. The cohesion is strengthened by the introduction of material particles (e.g. nitriding, aluminizing).
