“…However, the effect of v C on the size of the unsafe zone is negligible for realistic machine tool and cutting parameters with the exemption of low cutting speeds where process damping becomes relevant [14,15], or at low chip loads [2]. In other words, the size of the unsafe zone depends mostly on the cubic power of the chip thickness variation in (1), and it is roughly constant all along the lobes whatever vibration (chatter) frequency v C occurs in the system.…”

“…However, the cutting force identification tests are affected by the variations of material microstructures at different batches, dependency on cutting speeds and chip size. Due to uncertainties in the material behaviour, continuum mechanics modelling of chip formation [1,2] does not substitute the cutting experiments. Sample cutting force dependencies on chip thickness obtained from experiments and modelling approaches published in the literature are given in Fig.…”

“…The stagnation angle in their model is 58:5 AE 0:5 with the UCT of 2 to 20 lm and cutting speed of 100 m/ min. Jin et al [125] proposed a slip-line model for microcutting considering the effect of tool edge radius. The model based on the existence of stagnation point on the tool edge and the stagnation angle is calculated by the finite element model.…”

Micro-and nano-machining technology has been applied in industry to generate high-precision parts with micro/nanometric accuracy or feature size in the recent decades. Cutting is one of the most powerful manufacturing processes, and the material removal mechanism is urgently demanded by the industry to understand and improve the micro/nano-machining process efficiently at a low cost. This paper presents the recent advances in cutting mechanism and its applicability for predicting the surface generation and chip formation, especially when material is removed in micro-and nanoscale. In addition to the industry-concerned performance parameters, fundamental physical parameters such as stresses, strains, temperatures, phase transformation, minimum uncut chip thickness and size effects are discussed in this paper for the indepth understanding of the micro/nano-cutting process.
