Journal ArticleDOI
A review of surface roughness generation in ultra-precision machining
TL;DR: In this article, a review of the current state of the art in studying the surface roughness formation and the factors influencing surface rouness in UPM is presented. And several principle conclusions about the challenges and opportunities faced by industry and academia are discussed.
Journal ArticleDOI
A review of machine-tool vibration and its influence upon surface generation in ultra-precision machining
TL;DR: In this paper, the authors reviewed the latest research into vibration characteristics and the effect of vibration on surface generation in ultra-precision machining and found that active vibration can possibly be employed to improve surface quality influenced by passive vibration.
Journal ArticleDOI
A novel hybrid actuation mechanism based XY nanopositioning stage with totally decoupled kinematics
TL;DR: In this article, a parallel two degree-of-freedom compliant stage for XY nanopositioning was designed and tested using an innovative hybrid actuation mechanism, which mainly features the combination of two Scott-Russell and a half-bridge mechanisms for double-stage displacement amplification as well as moving direction modulation.
Journal ArticleDOI
Development of a piezoelectrically actuated two-degree-of-freedom fast tool servo with decoupled motions for micro-/nanomachining
TL;DR: In this article, a 2DOF FTS-assisted diamond turning is proposed and demonstrated to enable the cutting tool to move along two directions with decoupled motions using a novel guidance flexural mechanism constructed using the newly proposed Z-shaped flexure hinges.
Journal ArticleDOI
A review of fly cutting applied to surface generation in ultra-precision machining
TL;DR: In this paper, the authors focus on the current investigation of fly cutting applied into surface generation in ultra-precision machining (UPM), and the challenges and opportunities for further studies are discussed.
