is a short for a parameter that was defined to determine how well and effectively a specific production equipment is used.
OEE means Overall Equipment Effictiveness.
The parameter indicates the maximum possible output in defined production intervals.
This corresponds to the real productivity in percent.
The calculation is made by multiplying the factors availability (A) in percent, the performance (P) in percent, and the quality (Q) of the manufactured parts in percent.
This results in the formula to:
OEE = A * P Q
Example:
Availablility (0,85) x Performance (0,90) x Quality (0,985) = 0,75 OEE by means 75%
A (theoretical value) OEE of 100% means that there is 100% availability of an production equipment in a production.
This means that there are no production failures, a cycle time to speed performance of 100% and also 100% production of good parts.

In this case, a tolerance to be maintained is described by two parallel planes or straight lines.
These are spaced at the specified distance and are parallel to the specified reference.
A measured value must lie within these planes or straight lines.
For cylindrical moldings, the tolerance zone is formed by a cylinder with the diameter of the specified tolerance value.
The axis of the cylinder needs to be parallel to the reference.
Quality assurance: The axis of the hole must be within a cylinder of 0.01mm.

On technical drawings, this tolerance is specified if it is to apply to surfaces that the toleranced surface is to lie between two planes.
These planes are at the specified distance from each other and are perpendicular to the reference.
If cylinder axes are toleranced, they must lie within an imaginary cylinder with the specified diameter.
The axis of the imaginary cylinder is perpendicular to the reference surface.
Quality assurance:
Tolerance zone through two planes at a distance of 0.06mm from the reference surface A

This is a modern field of knowledge that refers to the comprehensive analysis and examination of plastics to identify material properties, damage or defects.
Plastics diagnostics includes methods such as microscopy, spectroscopy, thermal analysis and chemical analyses to determine the composition, structure and possible degradation processes of plastics.
It is often used to identify the causes of material failure and to develop solutions to improve material quality.
Plastics diagnostics play a central role in quality assurance, damage analysis and product development.
It makes it possible to make targeted optimizations in material selection and processing.
Potential weak points can be identified at an early stage and extend the service life of plastic products.

This term refers to a systematic examination of the physical, mechanical, thermal and chemical properties of plastics.
This makes it possible to assess their quality and suitability for specific applications. The most important test methods include tensile, compression and bending tests, hardness tests, impact strength tests and thermal analyses such as DSC and TGA. These tests help to precisely characterize the material properties and ensure that plastics meet the requirements of their subsequent application. The results of plastics testing are crucial for the selection of suitable materials and the development of new plastic products. They also enable quality control in production and the verification of material conformity in accordance with norms and standards. Plastics testing therefore makes a significant contribution to the safety, functionality and durability of plastic products.
