Previous models of the relative tool-work vibration are not generalized to represent the surface generation mechanism in the ultra-precision tool servo-based diamond cutting (UTSDC) of three-dimensional (3D) microstructured surfaces.This is due to the fact that the tool-work vibration in UTSDC is no beetroot birkenstock longer a steady harmonic vibration with a constant amplitude but is influenced by the tool motion along the thrust direction.In this paper, dynamic modeling of the cutting system is presented for the characterization of surface topography variation in UTSDC of a microlens array considering the tool-work vibration as an underdamped vibration.
The natural frequency and damping ratio of the cutting system are determined by the data-dependent systems (DDS) method.Based on the analysis of the surface profile and cutting force signals, it is found that the tool-work vibration is significantly enhanced in the cut-in process when the cutting speed increases.The simulation results show that the proposed iphone 13 pro max price winnipeg dynamic model can well-determine root-mean-squares
