P22: Advanced Metal Cutting #2

Aim

Through better understanding of today’s forefront of machining research the participants will be better suited to both implement and contribute to the continued development of the field of machining processes.

Course content

Analysis of production and production development of machining systems based on KPI numbers. Basic principles of metal cutting. Mechanical analysis and modelling, cutting resistance, load functions and variation numbers. Cutting force measurement and development of equipment for cutting force measurements. Thermal analysis and modelling. Stress analysis of cutting tools. Tribological analysis of surfaces in contact and contact relations in the cutting process. Archards modified wear equation and Colding equation. Mechanics of chip generation and process dynamics and segment formation. Vibrations and instability as well as process damping. Micro geometries and its influence on cutting process with respect to vibrations and mode-locking. Tool properties for different application areas. Tool material and tool deterioration regarding cracking, chipping, breakage and deformation. New potential high-performance cutting materials are processed in connection with the future challenges in metal cutting are discussed. Micro- and macroeconomic models for evaluation and simulation of the cost outcomes.
