Titel
'iTool' - Process and design considerations for innovative diamond tool making
Abstract
In various products that can be found in expanding markets such as medicinal devices, consumer products and measurement technology, smallest diffractive and aspherical structured optics are demanded. Due to the very high quality requirements regarding geometry and surface roughness only the diamond cutting process is feasible for the manufacturing of these optics and its mould inserts respectively. The applied diamond tools need to fit specifications regarding cutting edge and radius tolerances of up to 50 nm. Furthermore, the geometrical shape of state of the art diamond tools is limited to spherical edges. For this reason, the Fraunhofer IPT is developing a novel diamond grinding and lapping machine with an integrated interferometer-based measurement system for the manufacturing of ultra precision diamond tools with spherical and as well as aspherical cutting edges in one setting.
