Abstract
A cutter bit (1) with a cutting edge adapted to come into contact with the piece to be machined and a chip-cutter bit (2) superposed with an edge located at least along a portion of its length behind the first cutting edge. The two edges define between themselves a slot (9) giving access to a channel (10) provided in the tool, this channel extending along the length of this slot and being open at at least one of its ends. The tool is particularly useful for machining composite materials comprising fibers embedded in a resin.
Claims11
A cutting tool adapted to be secured to a tool holder, comprising at least one first cutting edge adapted to enter into contact with the piece to be machined and at least one second cutting edge located along at least a portion of its length behind the first cutting edge, these two edges defining between themselves a slot giving access to a channel provided in the tool, said channel extending along the slot and being open at at least one of its ends, the channel having a cross section which is elongated in the direction away from said cutting edges, said cutting edges lying in a plane which extends lengthwise of said cross section of the channel.
A cutting tool adapted to be secured to a tool holder comprising at least one first cutting edge adapted to enter into contact with the piece to be machined and at least one second edge located along at least a portion of its length behind the first cutting edge, these two edges defining between themselves a slot giving access to a channel in the tool, said channel extending along the slot and being open at at least one of its ends, said tool comprising two superposed bits having an interface between them, each of said bits having one of said edges and defining a portion of the wall of the channel, said edges lying in the same plane as the interface between said bits.
A cutting tool adapted to be secured to a tool holder, comprising at least one first cutting edge adapted to enter into contact with a piece to be machined and to cut said piece by relative movement of said tool and piece in one direction, and at least one second edge located along at least a portion of its length behind the first cutting edge, these two edges defining between themselves a slot that opens in said one direction, said slot giving access to a channel in the tool, said channel extending along the slot and being open at at least one of its ends.
