Abstract

A high bandwidth rotary fast tool servo (40) provides tool motion in a direction nominally parallel to the surface-normal of a workpiece (50) at the point of contact between the cutting tool (44) and workpiece. Three or more flexure blades having all ends fixed are used to form an axis of rotation for a swing arm (42) that carries a cutting tool (44) at a set radius from the axis of rotation. An actuator (68) rotates a swing arm assembly (42) such that a cutting tool is moved in and away from the lathe-mounted, rotating workpiece in a rapid and controlled manner in order to machine the workpiece. A pair of position sensors provides rotation and position information for a swing arm to a control system. A control system commands and coordinates motion of the fast tool servo with the motion of a spindle, rotating table, cross-feed slide, and in-feed slide of a precision lathe.
