2. Rake angle - Wikipedia

   en.wikipedia.org/wiki/Rake_angle

   Negative rake: A tool has a negative rake angle when the face of the cutting tool slopes away from the cutting edge at outer side. Positive rake angles generally: Make the tool more sharp and pointed. This reduces the strength of the tool, as the small included angle in the tip may cause it to chip away. Reduce cutting forces and power ...

3. Profile angle - Wikipedia

   en.wikipedia.org/wiki/Profile_angle

   The profile angle gives the direction of the tangent to a tooth profile. [1] In spur gears and straight bevel gears, tooth profiles are considered only in a transverse plane, and the general terms profile angle and pressure angle are customarily used rather than transverse profile angle and transverse pressure angle. In helical teeth, the ...

4. Chainsaw - Wikipedia

   en.wikipedia.org/wiki/Chainsaw

   Chainsaw engines are traditionally either a two-stroke single-cylinder gasoline (petrol) internal combustion engine (usually with a cylinder volume of 30 to 120 cm 3) or an electric motor driven by a battery or electric power cord. In a petrol chainsaw, fuel is generally supplied to the engine by a carburetor at the intake.

5. Chainsaw safety features - Wikipedia

   en.wikipedia.org/wiki/Chainsaw_safety_features

   The chain has to be properly matched to the guide bar and the saw. Chainsaw manufacturers specify a selection of suitable chains for each model of saw. Best safety requires that the chain is properly sharpened. One key sharpening parameter is the depth gauge setting. The depth gauge is the small steel protubera

6. Saw - Wikipedia

   en.wikipedia.org/wiki/Saw

   The basic version has a circular blade fixed at a 90° angle to the vertical. A "compound miter saw" has a blade that can be adjusted to other angles. A "sliding compound miter saw" has a blade that can be pulled through the work, in an action similar to that of a radial-arm saw, which provides more capacity for cutting wider workpieces.

7. File (tool) - Wikipedia

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

   Saw sharpening files are usually single cut to deliver a smooth finish. They are suited to sharpening saw blades and dressing tool edges, especially where a finer, sharper edge or smoother surface finish is desired. The Chainsaw file is one example, used primarily for sharpening chainsaws. These appear to have a round cross-section, but are ...

9. Center gauge - Wikipedia

   en.wikipedia.org/wiki/Center_gauge

   Center gauges and fishtail gauges [1] are gauges used in lathe work for checking the angles when grinding the profiles of single-point screw-cutting tool bits and centers. In the image, the gauge on the left is called a fishtail gauge or center gauge, and the one on the right is another style of center gauge. [2]
