Research and Development Work on Customers' Request
There is a long personal history of successful dedication to development for precision,
both as an employee as well as an independent technology consultant and researcher.
Research and Development Work with Public Funding
A speciality is the design and coordination of European research projects for Metrology.
This work includes usually the formulation of the research tasks and the entire project
plan and the allocation of work to suited partners.
.... here some nostalgic retrospectives of "firsts"....
(will be continued)

First sketch of Fibre Probe (1997)
First large ball plate of carbon fibre suited for CMM error correction (1986-2001)
First prototype of Disassemblable Ball Bar (1991), today the most used artefact for large CMM testing;
artefact built and marketed by KOBA, AIMESS, Retter, and Trapet Precision
First time systematic modelling of "elastic errors" (non-rigid body errors) of HAM machines (1990-1991);
similar algorithms and measurement methods used today by ZEISS, WENZEL, METROLOGIC
On the way to fast machine tool checking:
1. Using machining sequences on special 1D, 2D and 3D-artefacts and then measuring on a CMM and alalyzing;
2. First self-centring probe (EU project "MT-Check") measuring a ball tetrahedron
This image shows a funny but effective experimental improvization: using the machining artefact as a base for the ball tetrahedron. (2002)
Today the MT-Check probe is built and marketed by IBS-PE
In the following:
first publication in of Self-Qualification of "3D-Interferometer" (Multi-Lateration) and realization suggestions.
(1981-1982); the "long-time-sleeping" concept which was realized in the 1980ies only in form of a research-prototype at Aachen Univerity (WZL) has been re-vived by ETALON Germany and a similar system was developed from scratch and is marketed today as the "Laser Tracer"
