Cutting insert with chip control
Abstract
Abstract This disposable polygonal, indexible cutting insert is provided with longitudinally curved channels, along the side edges of the insert, meeting at the corners of the insert. These channels are also transversely curved. At each corner of the insert, V-shaped shallow grooves are depressed into the joining or merging portions of the deeper longitudinal channels. With this construction the shallow, corner V-grooves provide good chip control for shallow depth cuts of the cutting tool and for fine longitudinal feed of the cutting tool relative to the work piece, per revolution of the rotating work piece, whereas the longitudinally curved deeper channels alongside the edges of the insert provide for good chip control for greater depth cuts and for greater longitudinal feed of the tool relative to the work piece, per revolution of the work piece. When profiling, both the shallow corner V grooves and the deeper longitudinal side channels, automatically provide good chip control as the depth of the cut increases and decreases during the profiling operation.
