“…The most relevant ones are the cutting forces between tools and workpieces, which can excite the system resonances in a wide frequency band (primarily determined by the tooth passing frequencies and their harmonics) and induce chatter phenomena and high vibration levels (Altintas et al 2004, Mahnama et al 2012, Sam Paul et al 2016, Zigulic et al 2017. Additionally, inertial loads associated with rapid movements for tool positioning, or even vibrations transmitted by the ground, can trigger elastodynamic phenomena (Troncossi et al 2009, Wójcicki et al 2015.…”

Vibration monitoring and control are central topics for machine tools, since high vibration levels reduce the quality of machined surfaces and shorten the tool life. In order to predict potential vibration issues since the early design stage, it is necessary to implement ad hoc numerical models for modal analysis. This requires significant efforts and possible conflicts with tight production scheduling of companies. This work focuses on a specific family of rotary transfer machines for the manufacturing of parts related to lock&keys industry. It investigates the possibility to achieve an acceptable estimation of the elastodynamic behavior of the machine tools through limited modifications of the Finite Element (FE) models used for structural analysis, which are generally available in the early phases of the design process. The structural FE model of a new machine tool is implemented and validated through experimental tests performed on a prototype. Then, the elastodynamic FE model is derived and simulated. The numerical results are consistent with the data provided by Experimental Modal Analysis (EMA). Hence, the proposed approach is confirmed viable and will be integrated in the company workflow of future machine designs.

“…Many researchers have been simulated Orthogonal cutting with the use FEM simulation by using the Johnson-Cook plasticity model. Most of them were investigated tool wear, cutting force, temperature, heat transfer, deformation tool or workpiece material, chatter vibration during cutting process in lathe machining [1][2][3][4][5][6][7][8]. The HSS tool material was simulated where the model used in [6] for analysis bending occurring on material C1060 cutting process under constant conditions.…”

“…The HSS tool material was simulated where the model used in [6] for analysis bending occurring on material C1060 cutting process under constant conditions. The most of them using FEM 2D to simulate cutting process, 2D ABAQUS/explicit and FEM code Deform-2D being employed [7][8][9][10][11][12][13][14]. FEM simulation of cutting processes has been changed to be an analysis effective method for minimizing the use of experimental work.…”
