  2. Bow and warp of semiconductor wafers and substrates

    en.wikipedia.org/wiki/Bow_and_warp_of...

    Warp is the difference between the maximum and the minimum distances of the median surface of a free, un-clamped wafer from the reference plane defined above. This definition follows ASTM F657, [ 2 ] and ASTM F1390.

  3. Elastics (orthodontics) - Wikipedia

    en.wikipedia.org/wiki/Elastics_(Orthodontics)

    They can be used for many different reasons, such as Class 2 malocclusions, to reinforce anchorage in a case where an extraction has been done, to allow the maxillary incisors to move backwards, and to correct midline deviation and allow buccal movement of backward-tipped lower incisors. Orthodontists generally use 12-16 oz elastics (3/16") in ...

  4. Bridgeport (machine tool brand) - Wikipedia

    en.wikipedia.org/wiki/Bridgeport_(machine_tool...

    Machine tapers for tool holding included Morse tapers (on early models) and the R8 taper (a widely used standard that Bridgeport created) on most models. Both Morse and R8 allowed for both collets and solid holders, and a drill chuck could be held by either of the latter. Currently R8 and Erickson #30 Quick Change tool holders are available.

    Modern machine shop workstation, 2009. A machine shop or engineering workshop is a room, building, or company where machining, a form of subtractive manufacturing, is done. In a machine shop, machinists use machine tools and cutting tools to make parts, usually of metal or plastic (but sometimes of other materials such as glass or wood).

    en.wikipedia.org/wiki/Gateway_(telecommunications)

    On an Internet Protocol (IP) network, IP packets with a destination outside a given subnetwork are sent to the network gateway. For example, if a private network has a base IPv4 address of 192.168.1.0 and has a subnet mask of 255.255.255.0, then any data addressed to an IP address outside of 192.168.1.0–192.168.1.255 is sent to the network ...

    OS/2 Warp offers a host of benefits over OS/2 2.1, notably broader hardware support, greater multimedia capabilities, Internet-compatible networking, and it includes a basic office application suite known as IBM Works. It was released in two versions: the less expensive "Red Spine" and the more expensive "Blue Spine" (named for the color of ...

  8. Way (machine tool element) - Wikipedia

    en.wikipedia.org/wiki/Way_(machine_tool_element)

    The geometry of the way can vary depending on the situation. The most common types are flat, vee, and dovetail ways. Flat ways are used when there is little requirement for the slide to be constrained perpendicular to the axis of movement, or the constraint is being provided by another component or otherwise not needed, such as on the carriage of a lathe.

  9. Tap and die - Wikipedia

    en.wikipedia.org/wiki/Tap_and_die

    where is the tap drill size, is the major diameter of the tap (e.g., 10 mm for a M10×1.5 tap), and pitch is the pitch of the thread (1.5 mm in the case of a standard M10 tap) and so the correct drill size is 8.5 mm. This works for both fine and coarse pitches, and also produces an approximate 75% thread.
