Chronological Over-view

Continuity and development 50 years EXAPT-Verein

The paper tape was the symbol from the beginning of the NC technique. It was also put into the cradle of the EXAPT organisation. Later the slogan computer-integrated manufacturing (CIM) defined the scene and, in the meantime, one slogan follows to the next slogan ´digital factory´ - ´PLM´ - ´Work Flow´ - ´Lean Management´  … and mirrors the dynamics, with which is tried to rise to the new economic challenges, which specially arise from the rapidly preceding globalization. EXAPT has adjusted to this field of tension and asserts itself as re-search centre and system developer with its differentiated orientation. A positive balance can be drawn to the 40th anniversary. Continuity and competence with a view to the essential have enabled the spin-off company from the university sector to establish firmly in the area of CAD-CAM and offer the potential for a successful future in the partnership with the users and for the users.

On the occasion of the anniversary the most important steps on this successful path of the EXAPT-Verein from the founding idea up to now are sketched here in retrospect.

At the beginning of the 1960s four university institutes - the WZL of the TH Aachen, led by Prof. Opitz, the "Institut für Steuerungstechnik der Werkzeugmaschinen und Fertigungseinrichtungen der TH Stuttgart" led by Prof. Stute, the "Lehrstuhl für produktionstechnische Automatisierung der TU Berlin" led by Prof. Simon and the "Institut für Werkzeugmaschinen und Fertigungstechnik der TU Berlin" with Prof. Spur at the top - concluded after an investigation of the programming systems offered in the Federal Republic: "The available programming systems do not meet the production requirements of the German industry."

This conclusion was the starting-point for the development of the programming language and the programming system EXAPT, the four university institutes developed in cooperation with the industry. With EXAPT it was possible for the first time to program geometry and technology of different machining processes computer-aided. The result protection when creating NC programs, especially by graphic visualisation, was a part of the system as well as the parameter-controlled generation of NC programs, e.g. for part family variants or the macro technique for the provision of repetitive tasks. The prototype systems EXAPT 1 for drilling and milling processes and EXAPT 2 for turning operations were created in several years' development work in accordance with the American programming language APT.

The development of EXAPT was of great interest for research centres and the national and international indus-try. 19 company representatives met on 22.03.1967 in Frankfurt to found the "Verein zur Förderung des EXAPT-Programmiersystems". The association registered on 23.03.1967 made it its business to take over the research and development results of the EXAPT system after the expiration of the public funding and to put into practice as soon as possible.

The product range was extended permanently and adapted to new basic conditions, which arose especially from the areas NC controls, machine technique, integration requirements because of electronic networking, hard- and software technique, market and organizational processes for users.

The following chronology shows the develop-ment of the EXAPT-Verein from 1967 to 2017:

22.03.1967
19 companies get together in Frankfurt for the foundation meeting of the "Verein zur Förderung des EXAPT-Programmiersystems e.V." (EXAPT-Verein). EXAPT provides the system EXAPT 1 for drilling and simple milling processes.
