Learning Week I: Academic skills and advanced topics in CAD

The first Learning Week will take place in Barcelona from September 6 to 10, 2021. It will be a physical event but talks will be broadcasted online via zoom for those who cannot attend in person. Updated information on the COVID19 related measures in force in Barcelona can be found here.

The event will be co-organised with the Barcelona Graduate School of Mathematics (BGSMath) and the University of Strathclyde. It aims to help ESRs develop complementary and transferable skills in Academia. Topics to be covered include communication/presentation to diverse audiences, Fund-raising and Proposal writing, and Knowledge Transfer Basics. These sessions will often include hands-on activities.

The event will include a 2-day scientific workshop with courses on advanced topics of CAD. Confirmed speakers include Sandra Di Rocco (KTH), Denys Plakhotnik (ModuleWorks), Christian Arber (Topsolid), Michael Floater (U. Oslo), Tamás Várady (Budapest U. of Technology and Economics) and Jiri Kosinka (U. Groningen).

11:00 Tutorial [Part A]: Alexander Leutgeb (RISC-Software): Dynamic Cutting Force Prediction (During Simulation of Machining Processes) (Chair: A. Fabri)
Abstract: The problem domain is to predict the cutting forces during simulation of metal cutting processes. There already exist several force computation models. These models have in common, that for different material combinations (cutting tool and workpiece) the determination of their coefficients is a time consuming task by performing different metal cutting patterns with the real machine and measuring the resulting cutting forces over the time. The novel approach of our research project should learn this coefficients from regular machining processes. That means we need on the one hand the data from the simulation (machining parameters and geometric representation of cutter workpiece engagement) and on the other hand the measured forces of the sensors from the real machine. Because usually the real machines do not come with sensors providing force measurements we will use an Internet-of-Things sensor from Pro Micron, which measures the forces directly on the tool side. So from a Machine Learning standpoint we have to first correlate the time series data from the simulation with that of the sensor. Later on we perform model fitting/regression (linear & non linear) to learn the coefficients for the force computation model.
After the model is trained, the simulation of the machining process can predict the cutting forces over the time. The application of these forces is relevant for machine vibration analysis, feed rate optimization, increase of energy efficiency, geometric errors in finished workpieces caused by tool cutter deflections, and so on.

17:00 Seminar: Managing and sharing research outputs: all you need to knowcialis 80 mg
Presenters: Elli Papadopoulou, Athena RC/ OpenAIRE, Iryna Kuchma, Electronic Information for Libraries – eifl / OpenAIRE
Abstract: This is an introductory session to the Open Science model. It aims to ensure that all ESRs have a comprehensive understanding of the basics of Open Science and are able to apply them in their everyday work using available resources. Presentations will highlight good practices in scientific publishing and data management activities that increase researchers recognition and at the same time achieve compliance with European requirements (e.g. grants received under H2020, HorizonEurope and ERC). A “first-aid toolkit” will be provided so that researchers can practice Open Science skills at their own time and pace.
18:15 End of the Doctoral School
