A STUDY ON NOVEL COMPLIANT MECHANISMS FOR ULTRAPRECISION MACHINING

Ultraprecision machining and compliant mechanisms (CMs) are pivotal in advanced manufacturing, offering superior motion repeatability, zero backlash, and high output quality. This thesis develops three novel CMs for ultraprecision setups: a 1DOF CM with an improved stiffness-to-weight ratio for microstructured surfaces, a 2DOF topologically optimized CM for enhanced dynamics and reduced mass, and a MEMS sensor-embedded anti-tri-chiral (ATC) flexure hinge addressing motion inaccuracies. Leveraging additive manufacturing, topology optimization, mechanical metamaterials, and MEMS technology, the study introduces innovative design approaches for precision machine tools, advancing their functionality and performance in producing high-value components.
