On the precision single-point diamond machining of polymeric materials

This paper is a continuation of long duration research and it reports about new results in the investigation of wear of natural monocrystalline diamond cutting tool in single-point precision and ultraprecision machining process of thermoplastic amorphous polymeric materials for various application, e.g. for photon-optical and bioengineering applications. In these investigations we have been using up-to-date methods and devices, including atomic force microscope, interferometers and optical profilers, 3D topographic analysis systems, optical-polarizable microscope, etc. Wear criterion was chosen as the technological criterion of the diamond tool cutting wedge clearance face wear (hcf < 0.6 μm), what allows to provide high quality level of the machined surfaces of articles from polymers.
