WebFinally, the global and local chip flow angles are investigated under various conditions of tool geometry (edge inclination angle, lead angle, nose radius) and cutting parameters … WebAbstract. A full geometrical analysis of a cutting tool edge is made, in which an effective rake of universal application is defined in terms of the primary rake and the angle of obliquity of the edge. The fundamental angles are related in an easy manner to the traditional workshop terms, and may readily be applied to any cutting tool.
