Jargon

It merges in about about 80% of the Steele-1983 text, omitting some framing material and a very few entries introduced in Steele-1983 which are now also obsolete. This new version casts a wider net than the old jargon file; its aim is to cover not just AI or PDP-10 hacker culture but all the technical computing cultures wherein the true hacker-nature is manifested.

Experimental study on surface integrity and subsurface damage of fused

The ultra-precision grinding of fused silica in cross grinding modes has been carried out. The ultra-precision grinder is self-developed by National University of Defense Technology, shown in Fig.1. It adopts hydrostatic guideway, whose motion accuracy is less than 0.2 μm/ 200 mm. The spindle of grinding wheel is an air spindle, has a nominal

Surface microroughness of optical glasses under deterministic

01.08.1996This result is in contrast to loose abrasive grinding (fixed nominal pressure), in which surface microroughness is determined by the elastic stiffness and the hardness of the glass. We summarize measurements of fracture toughness and microhardness by microindentation for crown and flint optical glasses, and fused silica. The microindentation

Kaolin has a Moh's hardness of about 2. Of course, all of these cited values are useful only if the material in question is relatively pure and properly labeled. As will be noted later, fillers can be highly abrasive if they contain a significant amount of quartz impurity, which has a crystalline hardness of 7 (Wypych 1999). Refractive index

This material is commonly referred to simply as "quartz." It is compatible with silicon-wafer processing steps, and may find application as a substrate in RF MEMS as it is not conductive, eliminating eddy

Mechanism of material removal by fixed abrasive lapping of fused quartz

01.10.2019Blaineau et al. found that for the coarse abrasive grinding of fused silica, if the feed rate and depth of cut are minimized and the spindle speed is maximized, the depth of SSD is minimized. However, most of these studies focused on the surface and subsurface damages of traditional lapping technology, which can only satisfy the processing of ordinary optical glass

To sense the force at which grinding-milling is conducted and provide real-time feedback on the milling tool's feed-rate, load-cells are devised on 3 axes. Using an appropriate grinding-milling technique in combination with proper feedback to control the machining feed-rate, quartz glass is machined layer-by-layer under a ductile regime.

Silica, crystalline: quartz dust, cristobalite

Glass-producing industry: quartz sand as the most important starting material for the manufacture of industrial glass (50–80 %); very pure quartz (e.g. rock crystal, vein quartz) for the production of quartz glass or optical glass; quartz sand with increasing levels of impurities (e.g. sedimentary quartz sand) for the production of fused silica, crystal glass, sheet glass, glass fibre and

Quartz Glass: What Is It? How Is It Made? Properties, Uses

Grinding: The quartz glass surface may be smoothened and its thickness may be reduced, depending on the end-use application. Hot Forming. The quartz glass is quite complex to thermoform due to its high melting point and steep viscosity, allowing it to be formed on a very narrow temperature range. If the temperature is too low, the glass is solid; if the temperature is

02.03.2011Definition of pneumoconiosis. The term 'pneumoconiosis' is an abbreviation (and etymological corruption) of Zenker's pneumonokoniosis, 3 which derives from pneumon (lung) and konis (dust) and therefore translates as dusty lung; in practice the term is confined to the effects of mineral dust on the lungs. Diseases caused by organic dusts are

FAQ

The nature of diamond grinding on ultra hard materials translates into tight tolerances being routinely achieved. The actual limits to the attained precision depend on variables like the machine tool used, the general shape and size of the part, and the sequence of operations needed to complete the task.

High

09.04.2021The fused silica prepared by our process shows an only slightly higher absorption at 2750 nm than that of fused quartz and a much lower signal than that of regular, fused silica. The calculation gives an OH concentration of 12 parts per million (ppm) for the injection-molded glass and 5 and 102 ppm for fused quartz and commercial fused silica, respectively ( 33 ).

Advances and Processes in Precision Glass Polishing Technique

Fused quartz is used in applications where good ultraviolet light transmission, very good thermal stability and chemical inertness (resistance to stains) are required. Fused Quartz is harder and more difficult to polish than borosilicate, so the cost is higher. For applications where prolonged or periodic temperatures are more extreme or there is a need for higher purity, fused quartz is an

Synthetic Sapphira vs. Glass, Fused Quartz Silica

Fused quartz and fused silica are the amorphous form of quartz. Fused quartz is made from purifying and melting natural crystalline quartz, usually natural quartz sand. Fused silica is a purer version of fused quartz that is made from various silicon gasses. Chemically known as SiO2, silica is pure glass.
