On stability of emulated turning processes in HIL environment

Hardware-in-the-loop simulator for emulation and active control of chatter

“…HiL simulators have been shown to be useful to investigate chatter [3][4][5][6][7][8][9][10][11][12][13], and to actively control it [3][4][5][9][10][11][12][13]. Ganguli et al [3,4] and Mancisidor et al [5] used a cantilever beam approximating a flexible workpiece and actuators for cutting force emulation.…”

“…However, such setups have less space for mounting and testing actuators that are generally used for controlling vibrations in typical CNC milling machines or portal milling machines. Matsubara et al [6] and Stepan et al [7] , [8] used a realistic machine with an actual spindle unit and a dummy tool/workpiece to emulate chatter vibrations while incorporating speed-dependent dynamics. They, however, did not investigate any active damping strategies.…”

“…They, however, did not investigate any active damping strategies. Though the setups used in [6] , [7] , [8] are real machines with an actual spindle unit, they are costly. Mancisidor et al [9] , [10] and Sahu et al [11] , [12] , [13] have used a simpler flexure that approximates a linear flexible single degree of freedom workpiece.…”

Effect of axial force on the stability of milling: Local bifurcations around stable islands

“…The more precise description of either the material removal mechanism (see Altintas (2012); Stepan (2001); Kurata et al (2010)) or the dynamics of the machine tool (see Budak et al (2006); Kivac and Budak (2004)) helps reduce the extensive and costly laboratory tests in the detection of unwanted vibrations. The recently developed hardware-in-the-loop methodology (see Beri et al (2020); Matsubara et al (2015); Sahu et al (2020); Stepan et al (2019)) also provides an intermediate tool between theoretical modelling and experimental work by carrying out semi-virtual cutting processes.…”

In-Process Monitoring of Changing Dynamics of a Thin-Walled Component During Milling Operation by Ball Shooter Excitation

“…An additional challenge in this task is that dynamic behaviour can vary significantly during the machining process itself. The dynamic characteristics of a tool may vary, depending on the actual configurations of the machine tool structure within the workspace [19][20][21][22] and it may also change for different spindle speeds (e.g., Campbell diagram) [23]. In addition, the changing dynamic behaviour can also correspond to the workpiece, as its geometry varies according to the removed material quantity.…”
