2. Valve seat - Wikipedia

   en.wikipedia.org/wiki/Valve_seat

   Valve seats are often formed by first press-fitting an approximately cylindrical piece of a hardened metal alloy, such as Stellite, into a cast depression in a cylinder head above each eventual valve stem position, [1] and then machining a conical-section surface into the valve seat that will mate with a corresponding conical section of the ...

3. Multi-seat valve - Wikipedia

   en.wikipedia.org/wiki/Multi-seat_Valve

   Due to the compact layout of the multi-seat valve, its dimensions are smaller, hence the (sub-) system requires less space. [2] Furthermore, the surface in contact with medium inside the valve can be significantly reduced compared to the circular construction, which is advantageous in terms of cleaning and draining capability.

4. Valve guide - Wikipedia

   en.wikipedia.org/wiki/Valve_guide

   In the 1980s, many U.S. production engine remanufacturers began reaming valve guides, rather than replacing them, as part of their remanufacturing process. They found that by reaming all the valve guides in a head to one standard size (typically 0.008 in. diametrically oversized), and installing remanufactured engine valves having stems that are also oversized, a typical engine head can be ...

5. Rapid prototyping - Wikipedia

   en.wikipedia.org/wiki/Rapid_prototyping

   The first 3D rapid prototyping system relying on Fused Deposition Modeling (FDM) was made in April 1992 by Stratasys but the patent did not issue until June 9, 1992. Sanders Prototype, Inc introduced the first desktop inkjet 3D Printer (3DP) using an invention from August 4, 1992 (Helinski), Modelmaker 6Pro in late 1993 and then the larger ...

6. ACIS - Wikipedia

   en.wikipedia.org/wiki/ACIS

   The 3D ACIS Modeler (ACIS) is a geometric modeling kernel developed by Spatial Corporation (formerly Spatial Technology), part of Dassault Systèmes.ACIS is used by software developers in industries such as computer-aided design, computer-aided manufacturing, computer-aided engineering, architecture, engineering and construction, coordinate-measuring machine, 3D animation, and shipbuilding.

7. 2.5D (machining) - Wikipedia

   en.wikipedia.org/wiki/2.5D_(machining)

   A 2.5D machine, also called a two-and-a-half-axis mill, possesses the capability to translate in all three axes but can perform the cutting operation only in two of the three axes at a time due to hardware or software limitations, or a machine that has a solenoid instead of a true, linear Z axis. A typical example involves an XY table that ...
