  2. Machine taper - Wikipedia

    en.wikipedia.org/wiki/Machine_taper

    The Jacobs Taper (abbreviated JT) is commonly used to secure drill press chucks to an arbor. The taper angles are not consistent varying from 1.41° per side for No. 0 (and the obscure # 2 + 1 ⁄ 2) to 2.33° per side for No. 2 (and No. 2 short). There are also several sizes between No. 2 and No. 3: No. 2 short, No. 6 and No. 33.

  3. Thread angle - Wikipedia

    en.wikipedia.org/wiki/Thread_angle

    In mechanical engineering, the thread angle of a screw is the included angle between the thread flanks, measured in a plane containing the thread axis. [1] This is a defining factor for the shape of a screw thread .

  4. Windows Calculator - Wikipedia

    en.wikipedia.org/wiki/Windows_Calculator

    A simple arithmetic calculator was first included with Windows 1.0. [5]In Windows 3.0, a scientific mode was added, which included exponents and roots, logarithms, factorial-based functions, trigonometry (supports radian, degree and gradians angles), base conversions (2, 8, 10, 16), logic operations, statistical functions such as single variable statistics and linear regression.

    For example, the self-releasing NMTB/Cat taper is 3.5/12, which is only 16.5943° cone angle (8.2971°per side) (pictures available by typing "NMTB taper" into images.google.com). If one of the questions is "how did Morse know what degree of taper would produce self-holding rather than self-releasing", the answer is undoubtedly simple "cut and ...

  6. List of drill and tap sizes - Wikipedia

    en.wikipedia.org/wiki/List_of_drill_and_tap_sizes

    One of the most common ways to produce such threaded holes is to drill a hole of appropriate size with a drill bit and then tap it with a tap. Each standard size of female screw thread has one or several corresponding drill bit sizes that are within the range of appropriate size—slightly larger than the minor diameter of the mating male ...

  7. Reamer - Wikipedia

    en.wikipedia.org/wiki/Reamer

    A taper pin is a self tightening device due to the shallow angle of the taper. They may be driven into the tapered hole such that removal can only be done with a hammer and punch. They are sized by a number sequence (for example, a No.4 reamer would use No.4 taper pins).

  8. Drill bit sizes - Wikipedia

    en.wikipedia.org/wiki/Drill_bit_sizes

    One aspect of this method of sizing is that the size increment between drill bits becomes larger as bit sizes get smaller: 100% for the step from 1/64 to 1/32, but a much smaller percentage between 1 47/64 and 1 3/4. Drill bit sizes are written as irreducible fractions. So, instead of 78/64 inch, or 1 14/64 inch, the size is noted as 1 7/32 inch.

  9. Draft (engineering) - Wikipedia

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

    In engineering, draft is the amount of taper for molded or cast parts perpendicular to the parting line. It can be measured in degrees or mm/mm (in/in). Consider the fabrication of a hollow plastic box, without lid. Once the plastic has hardened around the mold, the mold must be removed. As the plastic hardens, it may contract slightly.
