Abstract [en]

Recent developments into virtual machining from a research point of view in combination with experiences in a collaboration project with machining companies spawned the question of how complex it is to setup a virtual machining solution and if such a solution is accurate. In the herein presented thesis, a virtual machining solution consisting of cutting data selection, vibration management, machine tool dynamics modelling, tool path programming and geometrical verification, physics based cutting mechanics simulation, geometrically based optimization, physics based optimization, and postprocessing have been successfully setup, tested and described. The physics based cutting mechanics simulation have been compared to analytical force calculations and force measurements. Physics based cutting mechanics simulation were shown to be more accurate by a factor of almost two compared to analytical force calcula-tions. A smaller case study to compare different approaches to tool path optimization was per-formed and physics based optimization showed greater promise compared to geometrically based.
