Principles of Cutting Edge Engagement

Knowledge of the basic principles of a machining method is an essential prerequisite for the full realisation of its potential. Yet research into the essential features of material removal with geometrically undefined cutting edges is beset with great difficulties. The determination of the cutting edges used in the procedure is hampered by the extremely complex microstructure of the tools. Because of the large number of grain points acting on the component part, material removal is made up of the sum of many different cutting edge engagements that remove the individual chips from the material surface
