Rotary fast tool servo component design
… of the components of a novel rotary fast tool servo (RFTS). The RFTS enables diamond turning of rotationally asymmetric optics, with an emphasis on eyeglass lenses. These components include the rotary arm which supports the cutting tool, a high resolution angular sensor for position …

Design and control of a long stroke fast tool servo
… the design and control of a linear long stroke fast tool servo (FTS) with integral balance mass. The long stroke fast tool servo consists of an air bearing stage driven by a unique three phase oil cooled linear motor. The linear FTS has a travel range of 25 mm and is capable of 100 m/s² …

A rotary fast tool servo for diamond turning of asymmetric optics
… The asymmetric features in such parts require a fast tool servo to synchronize the motion of the cutting tool with the motion of the workpiece spindle. At present, elements with low-amplitude asymmetry ( < 500[mu]m) can be fabricated on commercially-available machines. However, no device …

Design and implementation of a rotary fast tool servo for a turning machine
… the design and implementation of a rotary fast tool servo (RFTS) in a machine tool for turning ophthalmic lenses. To machine nonrotationally symmetric lenses, the cutting tool on the RFTS must move synchronously with the spindle rotation. Therefore, to cut a lens at high spindle speeds, the …
