Models of grindinginduced surface and subsurface

Combined the kinematics of grinding process, the theoretical models of surface damage (SD) and subsurface damage (SSD) depths are developed considering Fused silica is a typical brittle material However, surface damage (SD) and subsurface damage (SSD) appear unavoidably in the grinding process of brittle Models of grindinginduced surface and subsurface

Controlled material removal mode and depth of micro

A critical function for crack propagation for the single grit scratching of fused silica is developed based on the fracture mechanics The effects of original crack This study is based on fused silica samples prepared by pellet grinding using bound abrasive diamond grits with different matrices and with different grit sizes Fractal and multifractal analysis on fused silica glass formed by

(PDF) Ductile and Brittle Mode Grinding of Fused Silica

A creep feed taper grinding method was applied to investigate the relationship between maximum grit depth of cut and surface integrity of fused silica Combined the kinematics of grinding process, the theoretical models of surface damage (SD) and subsurface damage (SSD) depths are developed considering the strain rate Models of grindinginduced surface and subsurface damages in

Models of grindinginduced surface and subsurface

Many fused silica samples are processed under different grinding parameters, and their SD and SSD depths are measured In combination with the The existing research about ductile grinding of fused silica glass was mainly focused on how to carry out ductile regime material removal for generating very Micro/nano Indentation and Single Grit Diamond Grinding

Fractal and multifractal analysis on fused silica glass formed by

This work is based on the fractal and multifractal based study on the surface roughness of fused silica glass samples lapped with a deterministic grinding method Optical component fabrication involves highly controlled polishing and lapping methods The method used for polishing and lapping depends upon the application and the properties required The main properties of materials for the optical purpose are roughness (Ra) and Subsurface damage (SSD) The control of these parameters has to be done right from Fractal and multifractal analysis on fused silica glass NASA/ADS

High Efficient Precision Conditioning of the Electroplated Diamond
