CUTTING TOOL WITH ADJUSTABLE INDEXABLE CUTTING INSERT

摘要

A cutting tool (10) is provided and includes a plurality of cutting inserts (12, 100) located in respective insert pockets (14, 114). The cutting inserts (12, 100) each include a top cutting plane (60, 102) with at least one cutting edge (70, 72, 128, 130) and a bottom support plane (62, 104). The top cutting plane (60, 102) includes an engagement portion (64, 108) for mating with a respective engagement portion (66,110) located in the respective insert pocket (14, 114). A clamping wedge (18) clamps the cutting insert (12, 100) against the respective insert pocket (14, 114). A shear resistance created between the engagement portions (64,108) of the cutting insert (12, 100) and the respective insert pocket (14, 114) during operation of the tool (10) is greater than a centrifugal force created during operation of the cutting tool (10). In an exemplary embodiment, the engagement portions (64, 108) are shown as a plurality of serrations (67, 120). The cutting tool (10) is particularly useful in high speed milling operations.
