“…Cuba Ramos et al [10] found similar surfaces to those shown in Fig. 17e and f when micromachining AISI 1045 steel and attributed the surface pattern to the built-up edge formation and consequent inhomogeneous chip formation.…”

“…However, the structure height is smaller than the designed value of 200 μm. Based on Ramos's report [19], the radius of cutting edge is several micrometers in a new cemented carbide cutting tool. The edge radius of the textured cutting tool is measured by an optical microscope (Bruker NPFLEX, Billerica, MA, USA) after the WEDM process.…”

This paper studies micro structure fabrication by means of a textured tool cutting edge, which is manufactured by applying the wire cut electrical discharge machining (WEDM). Machining performance of the square structure fabrication on the tool cutting edge is investigated in the WEDM process, and the machining accuracy is explored in experimental analyses. In this proposed method, undesired overcut comes from the discharge between the processing debris and the side wall of the target structure. Furthermore, by applying the textured cutting tool, the target square structure is directly fabricated on the alumina workpiece with just a simple turning process, which verifies the feasibility of the proposed tool cutting edge textured method by applying the WEDM. This technology is expected to become a potential method for the mass production of micro structure surfaces in the future.

“…In case of microcutting, the main problem occurring during machining is related to the size effect [11,20]. This means that with a decrease of the depth-of-cut, a nonlinear relation between the uncut chip thickness and the cutting forces is observed.…”

In the paper, the concept of an electrochemically assisted microturning process is presented. This is a hybrid machining process in which microcutting directly removes the material while electrochemical passivation changes the conditions of material removal. A test stand was designed and built to investigate this process. The experimental part includes a discussion of the research methodology and a comparison of the straight turning results in the case of machining 1.4301 stainless steel without and with electrochemical assistance. The change of the main cutting force resulting from electrochemical assistance was selected as the main investigated technological factor. Based on this study, we can state that in the case analyzed here (when only passivation is taken into account), electrochemical assistance brings significant benefits when the depth-of-cut is ≤1 μm.
