WebThe effective rake angle is the combination of the tool holder’s angle of inclination and the rake built into the insert. The lead or entry angle is the angle between the direction of the cutting tool feed and the cutting edge. The tool nose radius is the angle formed by the point of the tool. This radius may be large for strength, or sharp ... WebEffective rake angles are highly negative which leads to a large compressive plastic zone ahead of and under the grain followed by a shallower tensile zone behind the grain. It was described in Chapter 14 that the depths of grain penetration are usually very small. This has implications for the geometry of the grain contact. WebWithout running any rake, the diffuser is limited by regulation to a shallower angle than seen in years gone by. By increasing the rake, the effective angle of the diffuser is increased, thereby increasing the potential peak … how earth got its beauty
