Abstract: Broadly contemplated herein, in accordance with at least one embodiment, is a multi-flute end mill configuration that maintains circumferential spacing between the rake surface and clearance surface adjoining two adjacent end face cutting edges, respectively, regardless of the number of flutes and the desired end face configuration.

Abstract: A face milling cutter has a shank portion adjoining a cutting portion. The cutting portion terminates in a plurality of cutting edges extending in a radial direction from a central axis of the face milling cutter. The cutting edges are convexly curved at least along a part of their length. A portion of the cutting edges proximate the central axis is nearer in an axial direction to the shank portion than a point, X, on the cutting edges that is farthest away from the shank portion. A distance Y, between the point, X, and the central axis is between 20% and 40% of a diameter, D, of the face milling cutter, and a central portion extends the distance, Y, and has a radius of curvature of about 110% of the diameter, D.

Abstract: A chatter-resistant end mill and a method of making such an end mill, in which the teeth of the end mill are unequally spaced apart to substantially reduce or eliminate vibrations produced during cutting of a work piece.

Abstract: A method of orbital milling is performed using an orbital end mill, which has a cutting bit designed for orbital end milling. The abstract of the disclosure is submitted herewith as required by 37 C.F.R. §1.72(b). As stated in 37 C.F.R. §1.72(b): A brief abstract of the technical disclosure in the specification must commence on a separate sheet, preferably following the claims, under the heading “Abstract of the Disclosure.” The purpose of the abstract is to enable the Patent and Trademark Office and the public generally to determine quickly from a cursory inspection the nature and gist of the technical disclosure. The abstract shall not be used for interpreting the scope of the claims. Therefore, any statements made relating to the abstract are not intended to limit the claims in any manner and should not be interpreted as limiting the claims in any manner.

Abstract: A method for making by assembling a tool to and in a tool holder, and the tool and tool holder, and the assembled tool and tool holder. The tool is shrink-fitted into a cylindrical bore of the tool holder, and a shoulder of the tool abuts an abutment face of the tool holder. Structure, such as press, a screw, a draw bolt, or a cylinder, for example, is provided to apply an axial force to the cutting tool to force the tool shoulder against the abutment face of the tool holder.

Abstract: A machining tool, such as a ballnose end mill, a flat end mill, or a drill, which has a center area that is designed for improved ejection of chips produced during cutting of a workpiece. The machining tool has an edge on the end or tip of the tool starting proximate to the central rotational axis of the tool at a position located a distance above the x axis and to the right of the y axis.

Abstract: A multi-purpose end-mill to be used for different machining purposes, in particularly useful for closed or open contours machining. The end-mill comprises a cylindrical shank portion connected to a first cutting portion provided with a plurality of spaced-apart cutting teeth and a second portion provided with a plurality of different spaced-apart cutting teeth.

Abstract: A rotary multi-tooth milling cutter, each tooth having a tooth face is provided. The tooth face has at least two sections, a first section nearest the cutting edge having a convex form as viewed in a cross section perpendicular to the cutter axis and a second section in a concave form.
