“…Wan [25] has experimentally verified that wear affects the change in cutting force in such a way that the feed and passive forces are more influenced by tool wear than the cutting force. It is further reported in his study that if there is an increase in wear on the clearance angle, the contact area increases and also the amplitude of the dynamic force oscillations increases, which leads to a reducing the stability of the cutting tool.…”

The article deals with the specification of the most suitable machining parameters for three newly designed end mills in the term of stability of the deep groove machining, at which the depth of cut is minimally twice higher the diameter of the cutter. Online vibration analysis was selected as a tool for goal achievement. The partial objective of the first phase of experimental research was to set the boundary conditions of vibrodiagnostics at the specification of the behaviour of three commercially produced milling cutters when the results were compared with the surface roughness achieved at the machining with individual cutting parameters. Vibrodiagnostic conditions were subsequently applied in the second phase of the experiment to determine the most suitable machining parameters of newly designed milling cutters. The Pinnacle VMC 650 CNC machining centre with Fanuc control system was used to perform the experiments. The material of cutters was S-grade sintered carbide, and all the designed cutters were PVD coated with the same AlTiN (aluminium titanium nitride) coating. The machined material was 16MnCr5 (1.7131) steel. The surface roughness analysis after machining by newly designed cutters pointed out that they are better as for the surface quality in comparison with the commercially produced end mills. Finally, it was possible to state that the four-tooth cutter 01-FVT with helix angles (β1= 39° and β2 = 41°) and tooth pitch (τ1 = 83° and τ2 = 97°) seems to be the best tool for milling deepshaped grooves among all the tested milling cutters.

This paper investigates the stabilizing effect of process damping at low cutting speeds for regenerative machine tool vibrations of milling processes. The process damping is induced by a velocity-dependent cutting force model, which takes into account that the actual cutting velocity is different from the nominal one during machine tool vibrations. The chip thickness and the cutting force are calculated according to the direction of the actual cutting velocity. This results in an additional damping term in the governing delaydifferential equation, which is time-periodic for milling and inversely proportional to the cutting speed. In the literature, this term is often assumed to be constant and is considered to improve stability properties at low spindle speeds. In this paper, it is shown that the velocitydependent cutting force model captures the improvement in the low-speed stability only for turning operations and milling with large radial immersion, while it results in a negative process damping term for lowThis work has been supported by theÚNKP-16-3-I.

“…However, for unstable milling process, the dominant frequency structure in the spectra can be characterized by complex coupling of TPF, resonance and self-excited vibration. Resonance can be easily described by the natural frequency of the machine tool structure while self-excited vibration are related to regenerative chatter or introduced by excessive tool chipping (Wan et al, 2011) (Moradi et al, 2013.…”
