The cutting edge of a tooth’s rake angle and its longitudinal axis serve as important components for designing the tooth. Not only does this impact its ability to cut, but it also determines the efficiency of material removal, how much vibration is experienced, and the outcome of the cut itself.
When it comes to tooth design, the choice of rake angle is carefully considered as a way to achieve a balance between several elements. A larger rake angle, for instance, allows for a more efficient cutting action plus less material removed. On the flip side, though, the greater rake angle could lead to more vibration and a lesser cut finish.
Normally, the rake angle is defined as the angle between the edges of a tooth and its longitudinal axis. Depending on the particular purposes, this angle may assume three possible values – positive, negative, or zero. Positive rake angles bring the cutting edges forward, resulting in enhanced cutting performance. Alternatively, a negative rake angle puts the cutting edges behind the longitudinal axis to minimize material removal. On the other hand, when set at zero, the cutting edges become perfectly parallel to the longitudinal axis of the tooth.
Alterations to the shape and position of the tooth can adjust its rake angle, swiveling it from round to square or vice versa. Replacing the cutting edge at a different location on the tooth will also affect the rake angle.
The rake of the tooth is an essential feature for determining how it functions – from the action of cutting to the amount of debris and shuddering to the total finish of the job. Having this angle precisely calibrated can lead to a remarkable transformation in the tooth’s capacity to perform.
