WebOct 5, 2024 · As a general rule, chip thickness must be at least as large as the radius of the cutting edge. For example, a 60 μm edge radius requires feed be adjusted to produce chip thickness of at least 60 μm. At a feed rate that is too low, the edge will rub and fail to cut the workpiece material. WebJan 1, 2011 · In a milling tool there are always two cutting edges jointed by a round corner (defined by the so-called corner radius, rε). The major edge is responsible for the material removal process whereas the minor edge is directly related to the final roughness produced on the machined surface.
