  2. Rake angle - Wikipedia

    en.wikipedia.org/wiki/Rake_angle

    In machining, the rake angle is a parameter used in various cutting processes, describing the angle of the cutting face relative to the workpiece. There are three types of rake angles: positive, zero or neutral, and negative. Positive rake: A tool has a positive rake when the face of the cutting tool slopes away from the cutting edge at inner side.

  3. Milling cutter - Wikipedia

    en.wikipedia.org/wiki/Milling_cutter

    The tooth cuts the material, and chips of this material are pulled up the flute by the rotation of the cutter. There is almost always one tooth per flute, but some cutters have two teeth per flute. [1] Often, the words flute and tooth are used interchangeably. Milling cutters may have from one to many teeth, with two, three and four being most ...

  4. Kuhn slide - Wikipedia

    en.wikipedia.org/wiki/Kuhn_slide

    The Kuhn slide (German: Kuhnsche Schleife) is part of a modified Walschaerts (German: Heusinger) valve gear on steam locomotives [1] and is named after its inventor, Michael Kuhn (1851–1903). The term is also used to refer to this particular type of Walschaerts valve gear system as a whole.

  5. Broaching (metalworking) - Wikipedia

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

    In rotary broaching, the broach is rotated and pressed into the workpiece to cut an axisymmetric shape. A rotary broach is used in a lathe or screw machine. In both processes the cut is performed in one pass of the broach, which makes it very efficient. Broaching is used when precision machining is required, especially for odd shapes.

  6. Rack and pinion - Wikipedia

    en.wikipedia.org/wiki/Rack_and_pinion

    A rack and pinion has roughly the same purpose as a worm gear with a rack replacing the gear, in that both convert torque to linear force. However the rack and pinion generally provides higher linear speed — since a full turn of the pinion displaces the rack by an amount equal to the pinion's pitch circle whereas a full rotation of the worm screw only displaces the rack by one tooth width.

  7. Hay rake - Wikipedia

    en.wikipedia.org/wiki/Hay_rake

    A hay rake may be mechanized, drawn by a tractor or draft animals, or it may be a hand tool.The earliest hay rakes were nothing more than tree branches, but wooden hand rakes with wooden teeth, similar in design to a garden rake but larger, were prevalent in the 19th and early 20th centuries, and still are used in some locations around the world.

  8. Chuck (engineering) - Wikipedia

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

    A drill chuck is a specialised self-centering, three-jaw chuck, usually with capacity of 0.5 in (13 mm) or less, and rarely greater than 1 in (25 mm), used to hold drill bits or other rotary tools. This type of chuck is used on tools ranging from professional equipment to inexpensive hand and power drills for domestic use.

  9. Rake (tool) - Wikipedia

    en.wikipedia.org/wiki/Rake_(tool)

    Garden rakes typically have steel teeth and are intended for heavier use in soil and larger debris. They have long, stiff teeth which must be able to withstand abrasion and bending forces. Bow rakes are a subset of garden rakes which separate the handle and bar with a bow-shaped extension which allows the flat back of the bar to be used for ...
