    en.wikipedia.org/wiki/Speeds_and_feeds

    Cutting speed may be defined as the rate at the workpiece surface, irrespective of the machining operation used. A cutting speed for mild steel of 100 ft/min is the same whether it is the speed of the cutter passing over the workpiece, such as in a turning operation, or the speed of the cutter moving past a workpiece, such as in a milling operation.

  3. Quick return mechanism - Wikipedia

    en.wikipedia.org/wiki/Quick_return_mechanism

    A quick return mechanism is an apparatus to produce a reciprocating motion in which the time taken for travel in return stroke is less than in the forward stroke. It is driven by a circular motion source (typically a motor of some sort) and uses a system of links with three turning pairs and a sliding pair.

  4. Gear shaper - Wikipedia

    en.wikipedia.org/wiki/Gear_shaper

    A gear shaper is a machine tool for cutting the teeth of internal or external gears, it is a specialised application of the more general shaper machine. The name shaper relates to the fact that the cutter engages the part on the forward stroke and pulls away from the part on the return stroke, just like the clapper box on a planer shaper.

    The table may be supported at the outer end. The ram reciprocates and the cutting tool, held in the tool holder, moves forwards and backwards over the work piece. In a standard shaper, cutting of material takes place during the forward stroke of the ram and the return stroke remains idle. The return is governed by a quick return mechanism.

    length and orientation of the bevel; Cutting edge profile with parameters. One of the most important cutting edge parameters is the K factor. It specifies the form of the cutting edge. 1 means a symmetric cutting edge. If the value is smaller than 1 the form is called a waterfall. If the value is larger than 1 it is called a trumpet.

  8. Reciprocating saw - Wikipedia

    en.wikipedia.org/wiki/Reciprocating_saw

    A reciprocating saw is a type of handheld, small, machine-powered saw, in which the cutting action is achieved through a push-and-pull ("reciprocating") or back-and-forth motion of the blade. The original trade name, Sawzall , is often used in the United States , where Milwaukee Electric Tool first produced a tool of this type in 1951.

  9. Rotary saw - Wikipedia

    en.wikipedia.org/wiki/Rotary_saw

    A rotary reciprocating saw is a type of saw that spins a cutting implement around a rotary axis, instead of thrusting it along a linear axis. The first use of such devices was in medicine , where cutting through bone warranted the need for a saw with minimal stroke length, and a cutting action that could be implemented through depth cut rather ...
