High Speed Cutting of Grey Cast Iron

High Speed Cutting (HSC) is recognised as one of the key manufacturing technologies for higher productivity and throughput. This report describes the application of High Speed Milling (HSM) to end milling of grey cast iron with polycrystalline cubic boron nitride (PCBN) and Cermet (HT) cutting tools in terms of performance and wear behaviour of these tools. The calculation of cutting forces by the use of an active magnetic bearing spindle (AMB) is dealt with as well as the resulting surface roughness depending on the tool geometry and wear behaviour.
