Abstract
One aspect of the invention provides a cutting tool used for peripheral cutting operations, comprising: a plurality of peripheral cutting edges, and a plurality of flutes disposed between the peripheral cutting edges, wherein each of the flutes includes at least one surface, and at least one depression recessed into the at least one flute surface, wherein each of the depressions defines a depression interior configured to trap cooling liquid during operation of the cutting tool, and wherein at least one of the depressions is dimensioned and disposed to enhance heat dissipation at least one of the peripheral cutting edges.
Claims36
A cutting tool used for peripheral cutting operations, comprising:
- a plurality of peripheral cutting edges, and a plurality of flutes disposed between said peripheral cutting edges,
- wherein each of said flutes includes at least one surface, and at least one depression recessed into said at least one flute surface,
- wherein each of said depressions defines a depression interior configured to trap cooling liquid during operation of said cutting tool, and
- wherein at least one of said depressions is dimensioned and disposed to enhance heat dissipation at at least one of said peripheral cutting edges.
A cutting tool comprising:
- a plurality of end face cutting edges, and
- a plurality of flutes which terminate, with respect to an axial direction of said cutting tool, at said end face cutting edges,
- wherein each of said flutes has at least one flute surface and includes at least one depression recessed into said at least one flute surface,
- wherein each of said depressions defines a depression interior configured to trap cooling liquid during operation of said cutting tool, and
- wherein at least one of said depressions is dimensioned and disposed to enhance heat dissipation at at least one of said end face cutting edges.
A method for maximizing heat dissipation during a material removal operation performed with a fluted cutting tool, comprising the steps of:
- a) forming at least one depression for promoting cooling, the at least one depression being recessed into a flute surface of the cutting tool at a predetermined region of the flute surface;
- wherein the predetermined region of the flute surface is friction-prone during said material removal operation in connection with a predetermined tool cutting speed and a predetermined workpiece feed speed;
- b) operating a machine tool, with which said cutting tool is coupled at said predetermined tool cutting speed and said predetermined workpiece feed speed, to initiate said material removal operation with respect to the workpiece;
- and
- c) causing chips formed during said material removal operation to flow along the flute surface and across the at least one depression while being supported by one or more ribs adjoining each of the at least one depression, until being discharged from the cutting tool, to facilitate an increase in heat dissipation as a result of a reduction in chip-flute contact area.
