The formation of tribo-layers during machining is very common phenomena, especially when machining 'free machining' steels. Several kinds of tribo-layers formed in metal cutting processes have been reported, layers of inclusions from the workpiece, oxide layers due to chemical reaction, plastic deformation layers, material transfer layers (MTLs) or built-up layers (BULs). A new tool-chip contact model...
The formation of tribo-layers during machining is very common, especially when machining 'free machining' steels. Previous flow zone models of metal cutting have not included the shear strain rate distribution at the tool-chip interface, although the distribution directly affects contact behaviour. A new flow zone model is developed, based on the concept of the cutting interface, which occurs where...
