Czech Technical University in Prague now offers a new fellowship program, the CTU Global Postdoc Fellowship. This new and attractive two-year fellowship-program offers excellent researchers who have recently completed their PhD the chance to continue their research career at CTU. Fellows receive a two year fellowship and become members of a team led by a mentor.
Digital Twins of machine tool and machining process represent upto-date advanced tools for more efficient process planning and improved machine tool performance. Unique concept of machine tool and proces Digital Twins for technology applications has been developed at CTU since almost 15 years. Currently it has reached a level of software solution, which allows virtual machining simulations for prediciting machining process results (time, quality and accuracy of machined surfaces) and optimization of process strategies and process parameters. Workpiece digital twin is a result of the complex simulation of the machine tool – process interaction and dynamic behavior of the machine tool and the workpiece. Our research goal is enhancing and mastering this concept for every-day practical implementation in the industrial production. Research topics: Dynamic interaction of compliant machine tool and workpiece, modeling of machining stability, predictions of machining performance and strategies for the optimization of machining process parameters and machine tool control parameters Integration of process data from the machine tool and from the simulation, development of strategies for automated analysis of machining process status and adaptive corrections of machining process parameters Inprocess monitoring of machine tool and process status, identification of chatter in machining Dynamics of machining thin-walled workpieces Virtual modeling of machine tool dynamic and thermomechanical behaviour during machining proces. Use of MOR techniques. Coupled digital models with retunable dynamic properties. Machine tool Digital Twin updating by using machine learning strategies.
