Research Group Profile

The history of scientific research in the area of technologies begins once with setting up in 1949 of a section of Tools, Devices and Apparatuses. Landmark moments in scientific research development were in 1953 and in 1964 when have been established the specialisation and Faculty of Machine Manufacturing Technologies, respectively. Within „Manufacturing Engineering” Department the research tradition goes on in the area of technologies. Relevant are the scientific achievements of professors Sauer L,. Secară Gh. and Roşca D. M in the area of cutting processes and tools, as well as professor’s Stănescu I. and Vasii-Roşculeţ S. ones in the area of manufacturing devices. Remarkable contributions in the area of manufacturing technologies had professors Drăghici G. and Ivan N. V. Professor Ivan N. V. added more features to scientific research by approaching in nineties new domains – CAD, CAPP, CAM and their integration. The prestige of the Effective Manufacturing Technologies and CAD/CAPP/CAM Systems group was recognized and strengthened by gaining numerous national and international research grants. These grants allowed developing a high performance research infrastructure. The research infrastructure of the group developed permanently, being added to it CNC machine-tools, data acquisition/distribution devices, high performance measurement equipment, and a modular set for devices building. Total investments in research infrastructure after 1990 overcome the amount of Lei 3 million. In 2013 the research group counts six PhD advisers, who coordinate thirteen PhD students.

R&D products, patents, use cases

1. Diţu V., DiaconuŞt. Combined drill. Patent #90 799/8.09.1986. The patent is a consequence of studying the thermocurrent at cutting process. The novelty is a drill having a cutting edge made of two different materials: HSS inside, and metal carbide outside. The length of cutting edge was optimized.

2. Stamate, V.M., Thermo-baro-polymerization inductive apparatus. Patent #RO126523 A2/2011, issued by

OSIM Bucureşti. The apparatus polymerizes composite materials in controlled temperature and pressure environment. The novelty of the apparatus consists of using a special way to warm the work liquid. The work-space and subsequently, the liquid warming are based on self-induction principle.

3. Stamate, V.M., Warming, melting, and modelling electric device. Patent#111888 C1/1998, issued by OSIMBucureşti. The device can be used in dental technique and in pasting parts on the electronic boards. Its, main characteristic feature is the ability to adjust the temperature of work head.

4. SanzVico, J., Stamate, V.M., Procédé et dispositif pour fabriquer des cigarettes par remplissage de tubes en papier avec du tabac. Patent request registration 10/01595 - 15/04/2010, 75 INPI-Paris 26
