Abstract: This paper presents the on-going activities performed on a Mori Seiki NL2000Y/500 mill-turn center, made available to the KU Leuven by the Machine Tools Technologies Research Foundation (MTTRF). Besides educational activities, the equipment has been involved in two research tracks. In a first track, the investigation of vibration assisted machining of ZrO2 is being studied. The development of machining strategies has led to surface roughness values (Ra) below 0.2 µm. In addition, the results are also compared with earlier performed machining experiments where no vibration is used. In the second track, focusing on energy efficient machining, a systematic energy-efficient approach, based on minimizing the production energy while complying with the required surface roughness, has been developed and validated to optimize the grinding stock for the turning-grinding process sequence. Compared to a conventional stock allocation method, the developed approach results in 16.6% of energy reduction for the turning-grinding process. In addition, a prototype software module has been developed to simulate the energy consumption of the machining processes based on the generated toolpath.
