Keynote title: Increased Performance and Flexibility in Machining through Process Modeling

Abstract: Machining is a commonly used manufacturing process in many industries such as automotive, aerospace, energy, die and mold, medical etc. due to its flexibility and ability to produce high quality parts. Although there have been significant advances in machine tool, control and CNC, CAD/CAM and cutting tool technologies over the last couple of decades, the productivity in these processes is still limited due to the process related problems such as excessive cutting temperatures and forces, process instability and chatter vibrations, part/tool/machine deflections etc. Current CAM systems or CNCs do not provide solutions to these problems. Process models (or digital twins), on the other hand, can be used to predict, avoid or reduce these problems through determination of the appropriate process conditions. In this talk, a brief overview of machining process modeling fundamentals such as chip formation mechanics, shearing, friction etc. will be given, and their use in calculation of process forces will be presented with examples. As one of the main and common problems in machining, cutting dynamics and stability will be explained through process-structure interactions where effects of structural dynamics and process conditions will be presented. Commonly used chatter suppression methods will be demonstrated with examples. Implementation of the models for production process simulations will be discussed, and process optimization will be demonstrated through industrial application examples. Modeling and simulation of special machining operations such as simultaneous turning/milling and turn-milling will also so be presented. The presentation will be concluded with future aspects machining process modeling and simulation.

Keynote title: 3D printing of parts using Metal Extrusion: an overview of Shaping Debinding and Sintering technology

Abstract: Additive Manufacturing (AM) is the fabrication of real three-dimensional objects from plastics and metals by adding material, layer by layer. One of the most common AM processes is the Material Extrusion (ME) based on different approaches: plunger, filament and screw. Material Extrusion technologies of metal-polymer composites is expanding and it mainly uses the filament or plunger based approaches. The feedstock used is a mixture of metal powder (from 55 vol% to about 80 vol%) dispersed in a thermoplastic matrix, as the Metal Injection Molding (MIM) materials. The Metal Extrusion process consists of three steps: shaping, debinding and sintering. The first step provides the extrusion of filament to realize a primary piece called “green part”; subsequent steps, debinding and sintering, allow to obtain a full metal part by dissolving the polymeric binder. The latter can be carried out using solvents, heat and the combination of them. Compared to other Metal AM process such as Selective Laser Melting or Direct Energy Deposition, the equipment used for FFF is low-priced and very easy to use. The interest, toward this technology, is driven by the low costs of the manufactured parts, the safety of feedstock materials and sustainability of the process. The aim of this keynote is to provide a general overview of the main Metal ME technologies considering the more technical aspects such as process methodologies, 3D printing strategy, process parameters, materials and possible applications for the pieces manufacturing on a 3D consumer printer.

Keynote title: Green and sustainable machining processes as a basis for innovations

Abstract: The manufacturing industry is a global base for prosperity and key to Europe’s economic, social and environmental sustainability. While the main driver for development are innovations, this does not mean to be focused just on the fundamental research innovations, but also to the innovations and their evolution to the level that make contribution to the society, are on lunched to the market, etc. For this purpose the EIT (European Institute of Innovation & Technology) has been established, also in the manufacturing field – EIT Manufacturing, with the objective to unite EU production in innovation ecosystem that would give to the EU products, processes and services unique value for making more global competitive and sustainable production. This is therefore emphasizing the need for usage of fundamental research results to be progressed in development and raised to high TRL levels and lunched into the industry, market, etc. In this presentation will be thus presented the EIT innovation community, with the challenges in manufacturing and machining industry, as well as EIT activities. Additionally, the speech will be focused on the case study on supported innovation project - Transitioning to a waste-free production – international cryogenic+MQL machining activity, with the road map of clean and dry cryogenic machining, where the fundamental research is lately been pushed to the industry and market with the help of EIT platform.
