Paper Abstract

The requirements for surface quality of workpieces such as metal-optics are increasing, specially if they are used as optics in high energy laser systems. This fact leads to an ongoing optimization effort of the microturning respectively fly-cutting process with a single point diamond tool. A selection of insufficiently machined workpieces has demonstrated that vibrations at the cutting zone modulate the surface contour. Recent measurements have shown that the static and dynamic compliance of ultraprecision machines has a great influence on these effects. In the past several ultraprecision machines have been studied and the results are presented here statistically. Further examinations have pointed out that it is possible to correlate the measured vibration amplitudes at tool and headstock during the cutting process with the generated texture on the workpiece.
