The project has the aim to study theoretically and experimentally high quality and precision Hydro Abrasive Jet Machining (HAJM) of multilayer hybrid glass, marble and stone, bonded, reinforced or composed with a wide variety of materials, as polymers, metals, polymeric matrix fibre reinforced composites, wood, thin film painted and enamelled glass specifically developed and designed for civil construction, building, furniture, decorative and architectural external and internal applications. Panels, prefabricated components and products of high quality made by these advanced multilayer composite and hybrid materials offer high performance, high and wide use potential, but they present many difficulties to be machined by means of conventional processes. HAJM seems to be the most suitable process for the machining of this typology of materials, but its applications is still limited by the lack of knowledge on the material removal mechanism, of predictive, optimization and control models capable to correlate machining results with machining conditions, and the lack of principles and rules to design and operate efficiently advanced HAJM cells for the specific multilayer hybrid materials.
The major aims of the project can be summarized as follows:
- theoretical and semi-empirical HAJM cells modelling for prediction, optimization and computer control;
- definition and validation of a prototype precision HAJM cell advanced architecture designed for multilayer hybrid materials;
- characterization of multilayer hybrid materials for the specific application and test parts preparation;
- design, execution and results evaluation of systematical HAJM experiments;
- physical and logical integration of HAJM in a CIM environment;
-study and validation of innovative solutions for high quality machining, jet catching and ergonomy and safety in operation and for abrasive, chips and water collecting, recycling and disposing;
- definition of HAJM domain, of advanced HAJM cell design rules, of product design rules for HAJM machinability, with reference to the specific hybrid multilayer materials typology.
The project will provide the basis for optimal HAJM of the specific typology of multilayer hybrid composite materials with the benefit for the export of both products made by these advanced materials and advanced HAJM cell.
