Current freeform metrology methods

Jessica DeGroote Nelson

Optimax, United States of America

Advancements in freeform manufacturing have been substantial in the last decade. The current limiting factor in the production of higher precision freeform manufacturing is metrology. This presentation will survey freeform metrology methods used in the industry today and highlight opportunities for future advancement in the field of freeform metrology to further higher precision freeforms.

A brief application of material parameters to predict polishing rates for optical glasses

This paper investigates the effects of material parameters of optical glasses on the polishing rate of these glasses. For this purpose, the material removal of various glasses was determined in laboratory tests under identical polishing conditions with respect to polishing pad and polishing suspension. The material removal was then evaluated for its dependence on material parameters. The goal of this paper is to derive a rule of thumb which allows an estimation of the material removal and the obtainable surface quality based on certain parameters of the workpiece material under comparable conditions. This rule of thumb can provide an initial insight into the polishability of a material and can be used to estimate polishing times and achievable surface qualities.

Ultra-short pulse laser-based fabrication process for lightweight structures in quartz glass applied for mirrors

David Bischof, Michael Kahl, Markus Michler

OST Eastern Switzerland University of Applied Sciences, Switzerland

In the following work a manufacturing process for light weight structures in Fused Silica is presented. Such structures can potentially be used for mirrors to decrease the mass by simultaneously ensuring high stiffness. This talk should give the audience the possibility to assess the selective laser etching technology for mechanical structures in the field of optical mirrors.

Development of a methodology for evaluating the process window of ductile machining for brittle-hard materials

Oliver Faehnle1, Thomas Liebrich2, Henrik Surberg1

1OST – Ostschweizer Fachhochschule, Switzerland; 2Rhysearch

This paper presents a standardized methodology for determining the process window for ductile machining of brittle materials. Its application for CaF2 is reported, identifying an optimized process window for single-point diamond turning on UPM machines by determining optimized process parameters.
