Based on the hobbing process characteristics, we propose a modification calculation method by calculating the vertical distance at engagement points between this envelope and the circular spline teeth profile, the modification values that ensure non-interference engagement is obtained. Besides, the introduction of the machining fillet feature into the tooth profile design is explored, revealing its positive impact on the stress distribution of harmonic drive. A finite element model is utilized to assess the effectiveness of modification and optimization of spatial tooth profile for harmonic drive. Finite element simulation results demonstrate that the modification and optimization considering fillet feature proposed in this paper effectively redistributes contact stress towards the middle section of the teeth and improves stress concentration at the ends.

Achieving nanometric surface finish and high form accuracy in sc-Ge via diamond turning machining (DTM) is challenging due to the material's brittleness. To overcome this, a novel groove generation model is developed to optimize DTM parameters and minimize brittle fractures using various cutting approaches. Additionally, the study demonstrates that a hybrid cutting approach, which combines constant angle and arc methods, achieves ductile-based machining and enhances surface quality significantly. Precise workpiece alignment is vital for ensuring high form accuracy in freeform optics; therefore, a fiducial-based method is developed for characterization using a mechanical profilometer, and a long-wavelength interferometry measurement. Final surface evaluation utilized a computer-generated hologram (CGH) in a Fizeau interferometer, achieving a form error of 0.47 μm and surface roughness (Sa) of 2 nm for cubic freeform optics which is acceptable in the infrared imaging system.

These parasitic resonances typically limit the actuation bandwidth, can lead to long settling times and can degrade the end-effector standstill performance when disturbance forces or floor vibrations are present. As a complicating factor, the parasitic resonance frequencies may vary over the workspace of the system. Conventional design guidelines focuses on stiff and lightweight design, leading to high parasitic resonance frequencies. However, for further improvement in performance, damping of some of the problematic resonances is required. In this work, a flexure-based manipulator is considered that exhibits performance limiting resonances, of which the frequencies vary with the deflection of the manipulator. An active damping approach, based on integrating piezoelectric material in the flexures which actively suppress the parasitic vibration modes is proposed and experimentally validated. Using a scheduled vibration controller, the actuation budget is effectively and efficiently used to suppress targeted parasitic resonances over the entire workspace, leading to a significant increase in the dynamic and steady state performance of the flexure-based manipulator. The resonance peak height of the first four parasitic resonances is reduced by a factor 10 over the majority of the workspace.
