The ADDICLEAN project will generate knowledge in the field of additive manufacturing of metal materials that will serve to develop technologies aimed at integrating these additive manufacturing operations with chip removal technologies in a machine designed for this purpose, as a means to promote the development and use of clean, green and low-intensity manufacturing processes in the consumption of energy resources and materials. To this end, the project proposes as technological objectives to generate fundamentals of metal additive manufacturing processes by laser and design and manufacture a competitive hybrid machine that integrates contributes more start-up to implement these technologies at an industrial level. Additive manufacturing is included in the list of the ten disruptive technologies with the highest capacity to transform the productive fabric in the 21st century, according to research in business and economics conducted by McKinsey Global Institute; it has also been rated by The Economist as the manufacturing technology that will change the world. Additive Manufacturing consists basically of manipulating material on a micrometric scale and depositing it accurately until a solid is built. This stage of deposition of material allows to obtain a piece of almost final geometry, which is subsequently subjected to a stage of machining for its finishing, in which the geometric precision and the surface finish of the provided material is improved. This hybrid process, additive + start, would replace the traditional starting processes, which start from a block of material, from which is eliminated by intensive machining, all the leftover material in the form of chips until the desired part appears. Compared to conventional technologies, additive technology provides and processes the minimum material, allowing a substantial saving of materials and energy. In addition, the handling of the material at micro scale allows to overcome the limits in the design of the parts imposed by conventional manufacturing, making it possible to design parts with textures and details that provide improved functionalities during their use, so they optimise the operation of the devices that integrate them, reduce energy losses and increase their useful life. In this context of opportunity, this project is a research commitment led by IBARMIA, in cooperation with the company BATZ, the Department of Mechanical Engineering of the UPV-EHU and TECNALIA, to develop the technologies that lead to the manufacture of the first Spanish hybrid machine (laser + starter) of metal part and facilitate its use in metal parts manufacturing companies, contributing to a transformation towards a greener industry while productive and competitive. In order to achieve the main objective, the following specific objectives are set out: 1) Integrate selective material input systems by laser into machine tools; 2) Characterising the additive metal base laser processes of three metal alloys that allow the optimal process conditions to be selected; 3) Develop process models to define optimal contribution strategies; 4) Define control strategies and optimal trajectories of the contribution process, and finally 5) Manufacture in an eco-efficient way two pieces of high added value that demonstrate the viability of the technology.
