ForewordThe 23rd edition of Innovative Manufacturing Engineering & Energy International Conference (IManEE 2019) is the result of a collaboration between the Department of Manufacturing and Industrial Management of the University of Piteşti (Romania) and the Department of Manufacturing Engineering of the “Gheorghe Asachi” Technical University of Iaşi (Romania).The first conference was organized in May 1996 at Iaşi and, since 1999, the conferences have been organized alternately, in Iaşi and Chişinău, by the collaboration of the Machine Manufacturing Departments from the “Gheorghe Asachi” Technical University of Iaşi (Romania) and from the Technical University of Moldova from Chisinau (Republic of Moldova). By considering the new trends and requests valid in the field of manufacturing engineering from the entire world, starting from 2013, the name of the conference was changed in „Innovative Manufacturing Engineering” and later in „Innovative Manufacturing Engineering and Energy”. Over the last few years, other departments from universities in Romania (Braşov, Bucureşti, Cluj, Galaţi and Piteşti) or other countries (Serbia, Greece) have been involved in organizing the conference.List of Honorary Committee, Scientific Committee, Organizing Committee, Keynote Speakers, Conference Chair, Sections Chairs, Sponsors and Partners are available in this PDF.
