Microstructural characterisation of material adhered over cutting tool in the dry machining of aerospace aluminium alloys

Machinability of a near beta titanium alloy

“…While cutting ductile workpieces (such as aluminium alloys) at low to moderate cutting speeds, a chip built-up edge significantly adheres to the tool rake face [27,28] due to the combination of compression force over the rake face and the visco-plastic state of the ductile metallic workpieces [29]. The built-up edge chip thickness increases with increasing ductility of the workpiece at lower cutting speeds, and no difference in the built-up edge chip thickness during cutting of workpiece materials with different ductility is observed at higher cutting speeds [30].…”

Fabrication of a micro-pin array with high density and high hardness by combining mechanical peck-drilling and reverse-EDM

“…In this part, the conditions of peck-drilling and the types of micro-holes are fixed, while the wave and frequency of the vibration are varied to study their effects on the formation of built-up edge (BUE) of micro-drills and the diameters of micro-holes on the entrance and exit sides. The BUE is come from that the workpiece material adheres to the chisel edge and rake face of micro-drill during mechanical drilling process, which can affect the life of the micro-drill and the quality of the micro-hole (Carrilero et al, 2002;Sánchez et al, 2005).Four experiments are executed and their machining conditions are listed in Table 3.…”

Influence of nanostructured CVD diamond coatings on dust emission and machinability of SiC particle-reinforced metal matrix composite

“…This adhesion phenomenon exists also on the rake face, creating a built up layer and a built up edge [13] which are taken off regularly by chip flow with abrasives particles. The smooth surface of C2 induced a great adhesion area, which put significant stress on the diamond film, resulting in the striping of diamond particles from tool tip.…”
