Conversion of tool angles from one system to another: Mechanics of Machining

Purposes of conversion of tool angles from one system to another • To understand the actual tool geometry in any system of choice or convenience from the geometry of a tool expressed in any other systems • To derive the benefits of the various systems of tool designation as and when required • Communication of the same tool geometry between people following different tool designation systems. Methods of conversion of tool angles from one system to another • Analytical (geometrical) method: simple but tedious • Graphical method – Master line…
