Abstract
The increase in productivity regarding metal machining is one of the main efforts in industries dealing with automotive components and air & space applications. This productivity is reached by increased cutting speeds (high speed cutting, HSC), high feed rates (high performance cutting, HPC), and overall the increase in metal removing rates (high efficient production, HEP). Especially difficult to machine materials like superalloys, high alloyed steels for turbine blades, and modern cast iron materials require high performance cutting tool systems with new approaches regarding coating, substrate material, chip geometry, and tool concept. In the following presentation this issues are targeted describing special tool and grade developments for HEP metal cutting processes. Additional new developments regarding cast iron materials with high fatigue resistance and increased machinability are highlighted as well. (...)
