Summary
Ultra-precision diamond machining is now capable of generating surfaces with sub-micrometer form accuracy and nanometer surface roughness, which are of high demand in the optical, electronic, and aerospace industries. The process of metrology and compensation is essential to align the diamond tool and control the surface generation process, and improve machining accuracy. One technical hurdle in high throughput precision diamond turning fabrication is metrology. This presentation will first discuss the challenges, review current techniques, and then discuss snapshot interferometric systems for on-machine metrology.
