Recent Advances in Micro/Nano-cutting: Effect of Tool Edge and Material Properties

Abstract

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.

Homogeneous and Localized Deformation in Poly(Methyl Methacrylate) Nanocutting

“…Strictly, molecular dynamic (MD) method is more suitable for the nanocutting simulation than the finite element method considering the strong interplay among atoms and molecules under nanoscale deformation [17,18]; however, the MD method can only model a rather small volume cutting due to its computational limits. Therefore, the commercial finite element code Abaqus/Explicit (version 2017) is chosen to investigate the nanocutting of PMMA.…”

On-machine and in-process surface metrology for precision manufacturing

“…In recent years, on-machine and in-process surface metrology is playing an increasingly important role in the process chain of traditional manufacturing that is composed of cutting, grinding and polishing for precision workpieces with complex shapes and/or extremely tight tolerances, such as freeform optics in head-up displays, large roll moulds for roll-to-roll replication and turbine blades of airplanes [220] [108] [27]. Similar trends are observed in the non-traditional manufacturing processes, such as additive manufacturing [199] and nano-scale manufacturing [55] [54].…”

Mechanically Enabled Two-Axis Ultrasonic-Assisted System for Ultra-Precision Machining

“…Complex surfaces are widely demanded in various applications including optics, bioengineering, and advanced manufacturing [1][2][3]. Ultra-precision diamond cutting is normally used for the fabrication of complex surfaces because it allows a high degree of freedom for the structural design [4,5].…”
