A universal cutting blade blank and cutting blades formed therefrom. The front face of the blank and blade comprises a pair of mounting surfaces with a front rake surface and connecting surface located therebetween. The cutting blade formed from the blade blank is more stable in a cutter head during cutting operations such as in the production of gears and related toothed articles. A single cutting blade blank can be used for forming inside and outside cutting blades regardless of the direction of cutter rotation.

Universal cutting blade blank and method for forming a cutting blade

Disclosed herein is a method of truing and angling the blades of a form-relieved face mill cutter during the blade sharpening process thus eliminating a separate time-consuming procedure for truing and angling. The position of the cutting edge of each blade is determined and a reference blade is selected. The sharpening plane of each remaining cutting blade is repositioned, if needed, such that after removing stock material from the blades in accordance with the newly repositioned sharpening plane, the cutting edge of each blade will follow essentially the same path when the cutter is rotated about its axis.

Method of truing and angling cutter blades by sharpening

Disclosed herein is a rotary cutter for cutting gears and the like. The rotary cutter has an axis of rotation and comprises a disc-shaped cutter head having a circumferential edge surface. The cutter head further includes an inner wall surface located radially inwardly with respect to the edge surface and being concentric about and extending parallel to the axis of rotation. The rotary cutter further includes a cutter ring located on the cutter head. The cutter ring has at least one stock removing surface located on a base portion with the base portion having an inside ring surface, an outside ring surface, and a base surface with the outside ring surface being perpendicular to the base surface. The cutter ring is in a radially expanded condition whereby the outside ring surface is seated against the inner wall surface of the cutter head and the base surface is seated against the first surface of the cutter head. The cutter ring is expanded by an expanding means located within the cutter ring and contacting the inside ring surface. The expanding means effects and maintains the cutter ring in a radially expanded position whereby the cutter ring is centered on the cutter head concentrically about the axis of rotation.

A face milling type gear cutting assembly including contiguous cutting tools positioned in a common slot with means for preserving clearance for chip removal between these tools. The cutting assembly also includes a tool clamping arrangement featuring a novel clamping block which is releasably attached to a screw element in situ.
