  2. Chuck (engineering) - Wikipedia

    en.wikipedia.org/wiki/Chuck_(engineering)

    By having twice as many clamping points, a six-jaw chuck induces less than half as much clamping distortion in a thin-walled workpiece, compared to a three-jawed chuck. Two-jaw chucks are available and can be used with soft jaws (typically an aluminium alloy) that can be machined to conform to a particular workpiece.

  3. Capstan equation - Wikipedia

    en.wikipedia.org/wiki/Capstan_equation

    The capstan equation [1] or belt friction equation, also known as Euler–Eytelwein formula [2] (after Leonhard Euler and Johann Albert Eytelwein), [3] relates the hold-force to the load-force if a flexible line is wound around a cylinder (a bollard, a winch or a capstan).

  4. Bending of plates - Wikipedia

    en.wikipedia.org/wiki/Bending_of_plates

    The left half of the plate shows the deformed shape, while the right half shows the undeformed shape. This calculation was performed using Ansys. Bending of plates, or plate bending, refers to the deflection of a plate perpendicular to the plane of the plate under the action of external forces and moments.

  5. Leadscrew - Wikipedia

    en.wikipedia.org/wiki/Leadscrew

    If the leadscrew has a collar which the load rides on, then the frictional forces between the interface must be accounted for in the torque calculations as well. For the following equation the load is assumed to be concentrated at the mean collar diameter ( d c {\displaystyle d_{\text{c}}} ): [ 12 ]

  6. Machine taper - Wikipedia

    en.wikipedia.org/wiki/Machine_taper

    An HSK connection depends on a combination of axial clamping forces and taper-shank interference. All these forces are generated and controlled by the mating components' design parameters. The shank and spindle both must have precisely mating tapers and faces that are square to the taper's axis. There are several HSK clamping methods.

  7. Vacuum table - Wikipedia

    en.wikipedia.org/wiki/Vacuum_table

    A vacuum table consists of a typically flat rigid surface with small holes to move air from under a workpiece, as to apply varying vacuum from between the desired workpiece and table to maintain a clamping force greater than that needed to machine a part, generally, in a mill, lathe, EDM (Electro-Discharge Machine), pantograph or any other ...

  9. Bending (metalworking) - Wikipedia

    en.wikipedia.org/wiki/Bending_(metalworking)

    In coining, the top tool forces the material into the bottom die with 5 to 30 times the force of air bending, causing permanent deformation through the sheet. There is little, if any, spring back. Coining can produce an inside radius as low as 0.4 T, with a 5 T width of the V opening.
