摘要

A cutting tool system is designed to have a combined sinusoidal-shaped and helical-shaped cutting edge formed by an assembly of aligned common cutting inserts each having a sinusoidal and helical cutting edge.

主权项

1. A cutting tool system comprising:
a tool holder comprising a plurality of common insert pockets positioned in a helical orientation about a longitudinal axis of the tool holder; and a plurality of common cutting inserts removably attachable to the plurality of common insert pockets in the tool holder to form at least one cutting flute on the tool holder, the at least one cutting flute comprising a helical grouping of common cutting inserts positioned in the insert pockets; wherein the common cutting inserts each comprise at least one sinusoidal and helical cutting edge; and wherein the at least one cutting flute comprises a sinusoidal and helical cutting edge positioned about the longitudinal axis of the tool holder and formed by alignment of the individual sinusoidal and helical cutting edges of the common cutting inserts that comprise the at least one cutting flute.
