Abstract
The modern machine tool is virtually unrecognisable in terms of its physical appearance and technical capabilities compared to those which were in use only a few years ago. Developments such as high speed spindles, live tooling and multi-axis machining have been combined with advances in cutting tool design, materials and coatings plus enhancements in cutting fluid performance in order to achieve unprecedented improvements in productivity. However, the continual development of increasingly difficult-to-machine materials, combined with the ever present desire for further increases in productivity, continue to drive the evolution of machine tools and machining processes. This paper will consider two techniques which although they have been known about for some time, have recently matured to the point that they are demonstrating commercial potential for further improvements in conventional machining processes; cryogenic cooling and ultrasonic assisted machining.
Cryogenic cooling of the cutting tool or the cutting zone has the potential to remove the heat generated during machining more efficiently that conventional cutting fluid and various researchers have investigated a range of techniques over the years. However, this presentation will describe research at WMG using a commercially available system and consider the advantages / viability of the process.
Ultrasonic assisted machining is also a technique which has been known to have a positive effect on certain aspects of machining for some time with several laboratory scale set-ups being developed by researchers. However, the system which is being used at WMG is integral within a commercially available, fully functional, 5-axis machine tool provided by DMG Mori Seiki. The application of this commercially available implementation of the technology will be reviewed along with some of the research work performed using this facility.
