Chip formation in monocrystalline iron-aluminum

CIRP Journal of Manufacturing Science and Technology, 2014
Abstract Iron-aluminum has an excellent corrosion resistance, low density and high specific strength compared to conventional steel. In addition, the raw materials and manufacturing costs of iron-aluminum alloys are relatively low. However, the machinability is challenging.

Chip formation analysis in micromilling operation

The International Journal of Advanced Manufacturing Technology, 2009
In mechanical micromachining, understanding the chip formation mechanism is critical to optimize the machining parameters and improve the workpiece performance. In this work, the entire slot micromilling process on Al6061-T6 by one flute carbide cutter was simulated by means of finite element method (FEM).

Fracture mechanisms in chip formation processes

Materials Science and Technology, 1997
AbstractMetal cutting is accompanied by extensive plastic deformation and fracture. Quick stop sectional specimens of the chip formation of medium carbon and resulphurised free cutting steel have been studied in order to determine the nucleation and growth mechanism of cracks during machining and their relation to the fracture process. During machining

Modelling chip formation of alloy 718

Journal of Materials Processing Technology, 2009
The aim of this article is to investigate the effect of different fracture criteria on the chip formation process. focusing on the formation of segmented chips and what happens around the cutting edge. Furthermore, it is investigated how well the finite element model is able to capture the transition from continuous to segmented chip formation in alloy

Mechanics of Chip Formation

1989
Abstract The relative motion between the tool and the workpiece during cutting compresses the work material near the tool and induces a shear deformation that forms the chip. This article discusses the fundamental nature of the deformation process associated with machining.
