High Speed Machining: Still a challenge for large scale and widespread industrial applications

TL;DRAbstract

The fundamentals of High-Speed-Machining (HSM) are clarified within the last 20 years and many effective industrial HSM-applications are state of the art. However, still a lot of machining processes like deep hole drilling and machining Difficult-To-Cut (DTC) materials, e.g. titanium and compacted graphite iron (CGI), are challenging to implement successful HSM strategies. The paper briefly introduces the fundamentals of HSM and mainly focuses on current research activities while machining titanium, steel and cast iron materials. By trend, automotive engine designers create their products out of higher strength cast iron materials with improved mechanical properties. Hereby machining of compacted graphite iron (CGI) is challenging. Cryogenic machining in combination with polycrystalline diamond tools could be reasonable to bridge the gap to large scale production and to overcome the difference in productivity comparing CGI and conventional grey cast iron machining. Furthermore, high sp
