Experimental Investigation of Subsurface Damages Made by Cup Grinding and Lapping Process of Optical Glass BK7 in Ductile Mode
Conventional material removal of BK7 optical glass will normally result in brittle fracture at the surface, generating severe subsurface damage and poor surface finish. Subsurface damages induced by grinding strongly influence the mechanical strength and optical quality of optical glasses. However, through ductile mode grinding it is possible to reduce the surface and subsurface cracks. It is m...
متن کاملSubsurface Damage in Microgrinding Optical Glasses
LLE Review, Volume 73 45 In cold processing of optical glasses by microgrinding,1,2 the resulting brittle-material-removal rate induces a cracked layer near the glass surface, referred to as subsurface damage (SSD). [Editor’s note: The acronym for subsurface damage (SSD) used in this article should not be confused with its more common use as an acronym for smoothing by spectral dispersion.] In ...

متن کاملSubsurface damage in single-crystal silicon due to grinding and polishing
Grinding and polishing are widely used surface finish operations for a variety of precision and delicate component of ceramics, such as silicon wafers and gauges. However, the formation and evaluation of the subsurface damage induced have not been investigated, although subsurface damage is extremely important to the quality of the products. Grinding and polishing are usually carried out by a s...
متن کاملModeling of Hygrothermal Damage of Composite Materials
Composite materials have been used extensively in various applications, such as mechanical engineering, aerospace engineering, and aviation thanks to their interesting mechanical properties. However, a substantial drawback in the use of such composite materials is that they absorb a significant amount of moisture when exposed to severe hygrothermal conditions. This factor dramatically affects t...
