Entry from a textbook
High Speed machining or cutting is defined as the cutting speed above which shear localization develops completely in the primary shear zone.
600 to 1,800 metres/minute is termed HSM.
1,800 to 18,000 metres/minute is termed Very high speed machining
Above 18,000 metres/minute it is termed ultra HSM
In the case of difficult to machine materials, High throughput machining is used.

Generally, the wheel velocity between 30 and 35 m/s is defined as conventional grinding;
The wheel speed exceeding 45 to 50 m/s is defined as high speed grinding;
The wheel speed between 150 and 180 m/s or higher is defined as Super-high Speed Grinding.
Volkswagen Group China applied the high speed grinding technique to grind engine camshafts. The wheel rotation-velocity is 4300 r/min, and 3000 workpieces can be ground each wheel dressing.

The term “stereolithography” was coined in 1986 by Chuck Hull. Chuck Hull patented stereolithography as a method of creating 3D objects by successively "printing" thin layers of an object using a medium curable by ultraviolet light, starting from the bottom layer to the top layer. Hull's patent described a concentrated beam of ultraviolet light focused onto the surface of a vat filled with a liquid photopolymer. The UV light beam is focused onto the surface of the liquid photopolymer, creating each layer of the desired 3D object by means of crosslinking (or degrading a polymer). In 1986, Hull founded the world's first 3D printing company, 3D Systems Inc. It is currently based in Rock Hill, SC. Stereolithography had success in the automotive industry. The technology continues to find innovative uses in countless fields of study.
Stereolithography works by focusing an ultraviolet (UV) laser on to a vat of photopolymer resin. With the help of computer aided manufacturing or computer aided design software (CAM/CAD), the UV laser is used to draw a pre-programmed design or shape on to the surface of the photopolymer vat. Because photopolymers are photosensitive under ultraviolet light, the resin is solidified and forms a single layer of the desired 3D object. This process is repeated for each layer of the design until the 3D object is complete.
• Digital Light Processing
The digital micromirror device (DMD) found at the core of DLP technology enables companies to develop uniquely fast and accurate 3D printers. These printers make use of liquid photopolymer resins to build objects. For each crosssectional slice of the object, the DMD projects patterned light
that selectively exposes and hardens the resin. Because an entire layer is exposed with a single pattern, fast build speeds are achieved independent of layer complexity. Projection optics can also be used to control the resolution on the image plane and adjust the layer thickness, leading to smooth and accurate finished parts. These benefits, combined with its proven reliability, make DLP technology the ideal solution for 3D printing systems.
