Marco Leonesio is born in Bollate (MI) in 1975. He obtained a MSc in Mechanical Engineering at POLITECNICO OF MILAN in 2000, with a specialization in Automation and Robotics. He conducted his Master Thesis work at CNR-ITIA (now STIIMA, Institute of Intelligent Industrial Technologies and Systems for Advanced Manufacturing), developing a software tool for the conceptual design of parallel kinematic manipulators. In 2001 he started working in DASM group (Dynamic Analysis and Simulation of Machinery) of CNR-STIIMA, coordinated by Giacomo Bianchi. In 2008 he became permanent researcher. Firstly, his activities ranged over multibody modelling and simulation, geometrical calibration of machine tools and parallel manipulators, and mechanism analysis. Since 2004 he started working on metal cutting analysis and simulation, in particular tackling the problem of process stability, integrating theoretical studies with proper experimental tests. In the field of mechanism analysis, he has conceived a new approach to assess the self-locking occurrence in closed kinematic chains, that has been the first attempt to tackle this problem in a general way. Recently, he was involved in process monitoring and control of grinding and milling processes. In February 2021 he joined the Ph.D. Program in Information Technology (Systems and Control) of POLITECNICO OF MILAN. In the framework of his Ph.D., he wants to develop control systems for industrial processes, exploiting hybrid machine learning and physic-based modeling approaches. He participated to several national and European projects (from 5FP to H2020), being responsible of particular tasks. He supervised and co-supervised master thesis in the field of machine tools and machining process and he is currently co-supervising a Ph.D. in Mechanical Engineering. Member of AITEM (Associazione Italiana delle Tecnologie Manifatturiere); project reviewer for the Italian Ministry of University & Research (REPRISE) and Ministry of Economic Development (in the framework of CNR – MISE convention).
