Bridging the Divide Between Iterative Optical Polishing and Automation.

Several recent business reports have described the global growth in demand for optical and photonic components, paralleled by technical reports on the growing shortage of skilled manufacturing staff to meet this demand. It is remarkable that producing ultraprecision surfaces remains so dependent on people, in contrast to other sectors of the economy, e.g., car manufacturing. Clearly, training can play some role, but ultimately, only process automation can provide the solution. This paper explores why automation is a challenge and summarizes multidisciplinary work aiming to assemble the building blocks required to realize automation.Highlights: Capturing polishing craft-expertise was academically successful, but commercially unviable due to personal privacy issues. Automating software communication between optical-design and manufacturing can minimise manufacturing cost and risk. Computational fluid dynamics of abrasive-slurries, plus real-time process-sensing, promises improved rocessconvergence. [ABSTRACT FROM AUTHOR]
