Our first Conference on Mechanical Engineering (OGET) took place in 1990. Over the years, the conference was at times part of the more comprehensive symposium called National Professional Days, but since 1995 OGET stands on its own as a separate and successful conference. We cultivate professional relationships with numerous universities from Romania and Hungary, but we also have valuable contacts in the business world. Among our returning participants and lecturers are also members of fellow associations and organizations from several cities in Hungary, such as Budapest, Miskolc or Veszprém. Papers presented at this symposium are published in a conference volume every year.
