Forces Shapes in 3-Axis End-Milling: Classification and Characteristic Equations

In 3-axis milling, cutting force analysis represents one of the main methods to increase quality and productivity process. this context, shape gives information both monitoring prediction However, is not unique, it changes according strategy, tool geometry, parameters. This paper presents a comprehensive approach predict classify shapes in milling operations. detail, proposed starts by classifying for single fluted endmill (i.e., flute shape), and, considering how may overlap another, extends classification general multiple-fluted endmill. Moreover, method provides, through analytical equations, angles, magnitude dimensionless parameters each key point, describing classified. Finally, was experimentally validated several tests different conditions.
