Single Point Diamond Turning Effects on Surface Quality and Subsurface Damage in Ceramics
Advanced ceramics, such as Silicon Carbide (SiC) and Quartz, are increasingly being used for industrial applications. These ceramics are hard, strong, inert, and light weight. This combination of properties makes them ideal candidates for tribological, semiconductor, MEMS and optoelectronic applications respectively. Manufacturing these materials without causing surface and subsurface damage is...
متن کاملLaser Induced Damage of Potassium Dihydrogen Phosphate (KDP) Optical Crystal Machined by Water Dissolution Ultra-Precision Polishing Method
Laser induced damage threshold (LIDT) is an important optical indicator for nonlinear Potassium Dihydrogen Phosphate (KDP) crystal used in high power laser systems. In this study, KDP optical crystals are initially machined with single point diamond turning (SPDT), followed by water dissolution ultra-precision polishing (WDUP) and then tested with 355 nm nanosecond pulsed-lasers. Power spectral...
متن کاملINCREASING THE LASER INDUCED DAMAGE THRESHOLD OF SINGLE CRYSTAL ZnGeP2 (PREPRINT)
The laser induced damage threshold (LIDT) of single crystal zinc germanium phosphide (ZGP), ZnGeP2, was increased to 2 J/cm at 2.05 μm and 10 kHz pulse rate frequency (double the previously measured value of 1 J/cm). This increased LIDT was achieved by improving the polishing of ZGP OPO crystals. The surface preparation of ZGP samples was determined to be of great importance because laser-induc...
متن کاملDuctile regime single point diamond turning of CVD - SiC resulting in an improved and damage - free surface
Silicon carbide (SiC) is one of the advanced engineered ceramic materials designed to operate in extreme environments. One of the main reasons for the choice of this material is due to its excellent electrical, mechanical or optical properties that benefit the semiconductor, MEMS and optoelectronic industry respectively. Manufacturing this material is extremely challenging due to its high hardn...
متن کاملDuctile behavior of optical glass in single point diamond turning
Single point diamond turning tests were carried out on a B270 type glass. Submicrometer cutting conditions were applied in order to generate ductile response during single point machining. The profile generated by the rapid removal of the tool tip from the machined surface, analyzed by atomic force microscopy, showed that the brittle-to-ductile transition occurs at a few tenths of micrometers. ...
