Sustainable management of machining waste
With the Industrial Revolution in the XVIII and XIX centuries, started a huge development of techniques and machines to improve and increase the product manufacture. One of the greatest fields of mechanical engineering is the manufacturing, that includes the machining processes which consists of cut the raw material (mostly metal) into a desired final shape and size. This processes requires specific techniques depending on the material and on the final shape desired. As the most of the processes, machining processes also demand work, tools, fluids and energy. The result of this is the final product and the waste of the processes (material, energy, fluids and tools). Currently is crescent the worries about the environmental damages and the green wave are present in all economic and industrial scenarios. Thus, the main objectives of this work are to study what types of waste are generated by machining processes, how it can be reduced and correctly treated as well as to present sustainable alternatives to conventional operations. As secondary objective, this paper presents a quick review of the main conventional machining processes by chip removal, its history, a short background about environmental responsibility and some economical justifications for concerns about machining waste.
