A schematic showing positive (left) and negative (right) rake angles. 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 ...
A stone rake is similar to a landscape rake, but with a narrower head of about 18 to 28 inches and is constructed from steel or aluminum. The head sits at a 90-degree angle to the handle. A thatch rake's primary function is to eliminate thatch—an organic layer situated between the lawn and the soil surface.
A motorcycle or bicycle fork rake, the angle at which the forks are angled down towards the ground; Rake angle in machining and sawing, the angle of a cutting head; Rake (geology), the angle at which one rock moves against another in a geological fault; Rake (theatre), the slope of a stage angled towards the audience for a better view
Side rake along with back rake controls the chip flow and partly counteracts the resistance of the work to the movement of the cutter and can be optimized to suit the particular material being cut. Brass for example requires a back and side rake of 0 degrees while aluminum uses a back rake of 35 degrees and a side rake of 15 degrees.
Setting the blade on an angle decreases the amount of force required, but increases the stroke. A 5-degree shear angle decreases the force by about 20% [citation needed]. The amount of energy used is still the same. The moving blade may also be inclined 0.5 to 2.5°, called the rake angle, to keep the material from becoming wedged between the ...
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].
In motorcycles, the steering axis angle is measured from the vertical and called the caster angle, rake angle, or just rake; [5] a 0° rake is therefore vertical. For example, Moto Guzzi [6] offers: a 2007 Breva V 1100 with a rake of 25°30′ (25.5 degrees) a 2007 Nevada Classic 750 with a rake of 27.5°
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 ...
