Correlation between micro-cutting and static indentation

Abstract

Micro-cutting as a material processing process is completely different from classic macro cutting. Defining the mechanism of micro-cutting is one of the goals followed by the world's researchers. One of the most common approaches so far is the identification of micro-cutting with the static indentation of an indenter, which is the subject of this paper. In the case of micro-cutting of brittle materials, where the presence of its destruction during processing is pronounced, by static indentation it is possible to establish which types of cracks occur inside the material. Another important thing is that with this method it is also possible to define the critical penetration depth below which brittle materials can be processed by the mechanism of plastic deformation.
