42CrMo4 is a steel alloy that contains chromium (Cr) and molybdenum (Mo) in addition to carbon. It is a heat-treatable steel with high toughness and strength, which can be used in a wide range of applications, including mechanical engineering, automotive engineering and aircraft construction.


Abrasive materials have a cutting characteristic. They can therefore be used for cutting processes such as grinding. This is often demonstrated by a particularly high hardness and the property of being able to generate sharp cutting edges.

Additive manufacturing processes

In an industrial context, 3D printing processes are often referred to as additive manufacturing processes. This is because these processes allow components to be manufactured by adding material layer by layer.

Adhesive strength

Adhesive forces determine the strength of the interface between the part to be joined and the adhesive layer.

Aerosol Jet Process

This process is also known as aerosol jet printing (AJP). This non-contact direct printing process allows the most delicate structures to be printed from a wide variety of substrates.


The German Platform Industrie 4.0 accomplished a standard for an homogenous and consistent implementation of an digital twin. The Asset-Administration-Shell (AAS) provides an interoperable and standardized information model.


In forming technology, the burr is the part of the component flowing over the edge of the engraving as excess material after the die has been filled. In most cases, this is subsequently removed by machining.

Cleave process

Cleaving refers to a process for preparing the end faces of glass fibers by controlled breaking.


A collimator is an optical device for parallelizing light beams, such as converging lenses or concave mirrors.

Confocal microscopy

Confocal microscopy is an optical imaging technique for generating high-resolution 3D images. Here, a laser scans multiple image planes, which are then assembled by a computer. Only the reflected light from the focal plane is detected through a pinhole. This allows very high resolutions to be achieved.
