“…Moreover, the dimple is on the "softer" grain "C" side, while the bulge is on the "harder" grain "B" side (Fig 3(a)). This effect is also observed in steels, at the interface between the harder pearlite and the softer ferrite [29]. The analysis of m after sectioning at a feed of 1 µm indicated that grain "E" opposed more to the deformation than grain "F".…”

tomy reveals the crystallographic information on the sectioned surface of the metallic block specimen. Philosophical Magazine, Taylor & Francis, 2010, 90 (29) Ultramicrotomy is widely regarded as a thin section preparation method for transmission electron microscopy (TEM) investigations. Here, we show that ultramicrotomy can also provide a simple path for microstructure analysis and assessment of mechanical properties for the sectioned blockface. Furthermore, electron backscatter diffraction (EBSD) analysis can be applied directly on ultramicrotomed surfaces without any additional polishing or etching. EBSD analysis relates the inherent cutting artifacts to the crystallographic orientations of the grains, hence delivering a rough assessment of their deformation resistance. TEM investigations revealed that crystallographicrelated cutting artifacts, which exhibit a wave-like pattern, are the result of the dislocation pile-ups close to the knife-specimen interface. We consider that this technique is suitable to be coupled with EBSD for three-dimensional microstructure reconstructions when used for serial sectioning of large volumes.

-Manufacturing is as old as the human race. Modelling and Simulation of Machining Operations are mainly based on the development of the Natural Sciences. Within the last 40 years there have been dramatically improvements of both: the scientific foundations of models and simulation techniques on one hand side and a strong industrial application on the other hand. The main focus of this paper is a critical assessment of the relevant single modelling methods for the simulation of machining, as well as providing some roadmaps for further directions towards the closed-loop modelling of machining. Limitations are discussed and challenges for the future are highlighted.

This article presents a laboratory machine designed to perform orthogonal micro-cutting experiments. The machine allows an accurate control of the various cutting parameters and a direct comparison of micro-and macrocutting tool-material data bases. Research with the machine will focus on validating the application of macrocutting data to at least a range of microcutting applications and to define the limits beyond which such applications are no longer possible. The paper describes the machine and its design specifications and provides the validation of the performances claimed. The machine can cut in a reproducible manner with depths of cut as low as 1 lm, at speeds in the range 50-1000 mm/s, while measuring the cutting and thrust forces. The variability in nominal depth of cut is equal or better than 1 lm. Application examples illustrate the influence of lubrication and lead additions on the cutting process and demonstrate that the machine is indeed suitable for the application for which it was designed.
