  2. Guillotine cutting - Wikipedia

    en.wikipedia.org/wiki/Guillotine_cutting

    Guillotine cutting is the process of producing small rectangular items of fixed dimensions from a given large rectangular sheet, using only guillotine-cuts. A guillotine-cut (also called an edge-to-edge cut) is a straight bisecting line going from one edge of an existing rectangle to the opposite edge, similarly to a paper guillotine.

  3. Grinding (abrasive cutting) - Wikipedia

    en.wikipedia.org/wiki/Grinding_(abrasive_cutting)

    Grinding is a subset of cutting, as grinding is a true metal-cutting process. Each grain of abrasive functions as a microscopic single-point cutting edge (although of high negative rake angle), and shears a tiny chip that is analogous to what would conventionally be called a "cut" chip (turning, milling, drilling, tapping, etc.) [citation needed].

  4. Cutting tool (machining) - Wikipedia

    en.wikipedia.org/wiki/Cutting_tool_(machining)

    The main features of the cutting edge are: form of the cutting edge: radius or waterfall or trumpet (reverse waterfall) cutting edge angles; form and size of the chamfers; The measurement of the cutting edge is performed using a tactile instrument or an instrument using focus variation. To quantify a cutting edge the following parameters are used:

  5. File (tool) - Wikipedia

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

    Joint round edge files are parallel in width and thickness, with rounded edges. The flats are safe (no teeth) and cut on the rounded edges only. Used for making joints and hinges. Knife files are tapered in width and thickness, but the knife edge has the same thickness the whole length, with the knife edge having an arc to it. Used for slotting ...

  6. Tool and cutter grinder - Wikipedia

    en.wikipedia.org/wiki/Tool_and_cutter_grinder

    During normal use, cutting edges either wear and/or chip. The geometric features of cutting tools can be automatically measured within the CNC tool grinder and the tool ground to return cutting surfaces to optimal condition. Significant software advancements have allowed CNC tool and cutter grinders to be utilized in a wide range of industries.

  7. Sharpness (cutting) - Wikipedia

    en.wikipedia.org/wiki/Sharpness_(cutting)

    Sharpness refers to the ability of a blade, point, or cutting implement to cut through materials with minimal force, and can more specifically be defined as the capacity of a surface to initiate the cut. [1] Sharpness depends on factors such as the edge angle, edge width, and the fineness of the cutting edge, and is aided by material hardness.

    The highest 36-hole cut came in 1955 at an astounding 15-over par. The lowest came just last year, when the cut was 2-over par at Los Angeles Country Club. The 1996 U.S. Open saw 108 players make ...

  9. Built up edge - Wikipedia

    en.wikipedia.org/wiki/Built_up_edge

    The built up edge effectively changes tool geometry and rake steepness. It also reduces the contact area between the chip and the cutting tool, [1] leading to: A reduction in the power demand of the cutting operation. [1] Slight increase in tool life, since the cutting is partly being done by the built up edge rather than the tool itself. [4]
