Smart Green Machining

In the manufacturing sector in the last century and especially last decades, the emphasis was placed on productivity, efficiency and economic return to the detriment of an efficient ecological model. Today climate change and the resulting ecological awareness add a new card that must be ( played) in the industrial world. This fight challenges against global warming requires new paradigms for all industrial sectors and the world of machining is therefore awaiting a breakthrough to be able to reduce its environmental impacts. Besides, tools have emerged to calculate carbon footprint, to analyse life cycle, to improve recyclability and circularity. They are helped by the continuous improvement of simulation tools, the capacity to store information and data and can be coupled with concept as lean management. Nowadays, artificial intelligence is also usable and start to be included in a lot of manufacturing sectors. Nevertheless, machining still stay the poor relation of this evolution even though it is one of the major manufacturing processes in the world and is generally the basis of production’s means. Moreover, the emerging of new processes as Additive manufacturing (AM) will not fully replace machining as it remains an excellent industrial answer particularly for finishing AM parts. Use of embedded and miniaturized sensors can provide access to crucial data that can be exploited by new surveillance systems and AI algorithms. That should lead to several innovations in the machining field, such as cutting aids, dry cutting, green lubricant strategies, new toolpath optimizations, etc. this optimisation have to be managed with digital tools, like numerical twins for example, in order to be perfectly effective.
