“…To reach good functionality and suitable mechanical properties different manufacturing processes for the surface modification are possible, for instance micro milling [1] or laser structuring [2]. These processes introduce very small notches, whose in dimensions which vary from smaller than the grain size up to a depth of a few grains, into the component surfaces.…”

Surface modification could improve functional or mechanical properties of components, which are used for example in biotechnological or automotive applications. Thereby, small structures produced by micro milling or laser structuring processes are in the same order as the grain size. They act as geometrical notches and could reduce the mechanical properties. In this work we will show detailed investigations of the fracture morphology of tension-compression tested micro notched specimens. The fracture surfaces were analyzed with a Scanning Electron Microscope (SEM) to determine the location of the failure. Furthermore metallographic microsections of some specimens were prepared to analyze the crack growth in detail: the aim is to investigate whether the crack propagation is affected by metallurgical features, such as the crystallographic orientation of the grains or microstructural barriers like grain boundaries. With these analyses we expect to be able to correlate the different stages of crack growth. The contents of this work are part of a research topic of the Collaborative Research Centre 926 "Microscale Morphology of Component Surfaces".

“…The axial cut depth was a p =10 l m, the feed per tooth f z =0.42 l ma nd the resulting surface roughness R a <0.1 l m. In as econd step, micro-notches were produced with5 0 l md iameter microend-mills by micro-slot milling. The tools used weres ingle-edged micro-end-mills withacylindrical cutting section, aflat face and aminor cutting edgeangle of v r ' =12 8 [16].

The functionality of components can be improved by surface modifications such as micro-milling. The micro-milled structures (notches) can cause changes in the mechanical properties of the components. To be able to predict or prevent component failure, the influence of these micro-milled notches on the deformation behaviouro fc ommercially pure titanium under tensile loading is investigated. Quasistatic tensile tests show that the tensile strengthisincreased by deeper notches and the fracture elongation of the specimens decreases. Metallographic analyses and nanoindentation tests of systematically interrupted tensile tests at different strain rates show the developmento ft he plastic deformation and the inhomogeneous deformation behaviour of the material.

“…Recent research associated with the micromilling process has focused on issues such as machine tool design [8][9][10][11][12][13], miniature cutting tools [14][15][16], process mechanics [17,18], surface finish [19] and CAM systems [20][21][22]. However, in the research literature there is relatively little attention to the micromilling process planning issue, i.e.…”
