Professor Anthony Beaucamp's research lab specializes in advanced finishing technologies for precision engineering components, with a focus on ultra-precision surface finishing using innovative methods such as fluid jet polishing, computer-controlled sub-aperture polishing, and shape-adaptive grinding. The lab addresses critical challenges in finishing additively manufactured titanium alloys, photomask substrates for extreme ultraviolet lithography, and diamond-turned optical surfaces, emphasizing surface integrity, nanoscale accuracy, and the mitigation of mid-spatial frequency errors. Key research directions include process optimization for ultra-smooth surfaces, minimizing surface defects, and enabling next-generation optical and biomedical components through deterministic, high-precision finishing techniques.

In recent years, rapid prototyping of titanium alloy components for medical and aeronautics application has become viable thanks to advances in technologies such as electron beam melting (EBM) and selective laser sintering (SLS). However, for many applications the high surface roughness generated by additive manufacturing techniques demands a post-finishing operation to improve the surface quality prior to usage. In this paper, the novel shape adaptive grinding process has been applied to finish
