“…The smaller the Dr value is, the sharper the cutting edge is. Yussefian et al [62] proposed a method to identify the cutting edge by the adaptive placement of the knots that minimizes the residual error from fitting the B-spline to the tool profile data. Subsequent to edge identification, the edge is modeled by parametric quadratics.…”

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.

“…It is evident from the background study that the asymmetrical edge hone has an impact on tool life and surface quality. But it has to be ensured that the extreme care is taken while measuring the edge profile since incorrect measuring methods will lead to a false characterization [9,10]. A decrease in form factor with larger contact length along flank face resulted in a increase in tool load as well as tool wear [11,12].…”

Cutting edge preparation is proven to improve the tool life by avoiding sudden failures. Honed edge is effective in stabilizing the tool but has an adverse effect on surface quality. Tailored edge draws attention for research in improving the tool life and surface quality compared to symmetric honed edge. This research describes the advantages and limitations of trumpet edges over symmetrically honed edges in tool life and surface quality. The analysis carried out in milling of AISI 4140 steel with the trumpet edge of K=1.6 produced a surface of stable Ra value around 0.2μm with good quality. The tool life was not significantly varied with the trumpet edges since the both trumpet edge and symmetrical edges resulted in a tool life around 95 minutes. The results predict a distortion of tailored edge as it machines the work piece since the K-factor was reduced from 1.6 to 0.9.

“…1. Terminology of tool edge profile [17] In terms of edge characterization, it has thus far been expedient in most instances to specify the geometry of honed edges by a simple edge radius parameter. This inherently assumes the edge profile that bridges the rake and flank faces to conform to an arc of a circle.…”

The paper deals with the issue of cutting edge preparation and tool treatment before the coating and their influence on the tool life of coated cutting tools. The aim was to examine the influence of cutting edge radius sizes on the tool life of cemented carbide turning inserts. Theoretical analysis was focussed on the issue of cutting edge microgeometry, discussing the classification and importance of cutting edge microgeometry. The most famous and used edge preparation methods are summarized in article along with the results of current research of famous tool companies and institutions. In this article, the tool lives of cemented carbide turning inserts which were prepared by several methods were compared. Cemented carbide turning inserts were deposited by AlCrSiN nanocomposite hard coating. Long-term tool live tests were carried out on DMG CTX alpha 500 turning centre. The tool wear of cemented carbide turning inserts was measured on Dino-Lite digital microscope during the turning. The tool lives of prepared cemented carbide turning inserts with required cutting edge radius and unprepared ones were compared. These results were investigated in the process of machining of austenitic stainless steel material X6CrNiTi18-10 by DIN EN (AISI 321), which shows higher strain hardening tendency.
