| Environmentally conscious hard turning of cemented carbide materials on the basis of micro-cutting in SEM: stressing four kinds of cemented carbides with PCD tools

Abstract : Environmentally conscious hard turning and technology has placed more importance on the machining process. In
this research, the possibility of environmentally conscious hard turning of cemented carbides was studied. The effects
of cutting methods of dry and wet (vegetable oil mist, and mineral oil) and work material on cutting resistance and
wear characteristics of cutting tools were experimentally investigated. The turning and micro-cutting process in SEM
was carried out by using four kinds of tungsten carbides with the PCD cutting tools. Specifically, an emphasis was put
on the effect of WC and Co additives in four kinds of cemented carbides on machinability and tool wear characteristics.
The tool wear width and the cutting resistances were measured, and the worn flank was observed..
