Ultra-high speed turning operations are very rare, unlike their milling counterparts, which are becoming a popular production technique for aerospace machining strategies of late. The technique in this current work, utililizes the precision placement of a large diameter circular workpiece in a dual-plane balanced dogless-driven adaptorkolder in the spindle of a vertical machining centre. The turning tool with its associated cutting insert is situated radially to that of the workpiece periphery, the tool being situated on a Kistler platform dynamometer, enabling the simulataneous collection of cutting force data whilst an axial turning (in-cut) pass occurs. Surface speeds are generated in a
