摘要： A cutting element for a tool to create a helically extending, trapezoidally undercut groove in a cylindrical surface of a bore. The cutting tool, preferably configured as a cutting insert, has groove-cutting teeth to create a symmetrically cross-sectioned groove which are arranged in series in a division harmonized with the pitch of the groove to be created. These groove-cutting teeth comprise at least one pre-machining tooth to create and machine a base groove and several trapezoidal teeth following the at least one pre-machining tooth, which have a tooth head profile which expands trapezoidally in cross-section in the vertical direction of the tooth with two flanks delimiting a flank angle for further machining the base groove to a trapezoidally undercut final cross-section. The flank angle delimited by the two flanks increases from at least one trapezoidal tooth to a following trapezoidal tooth to a defined final dimension.

摘要： The present disclosure relates to cubic boron nitride (cBN) cutting elements that have high cBN content and that are cuttable by electric discharge machining (EDM). A cutting element according to an embodiment includes a self-sintered polycrystalline cubic boron nitride (PCBN) compact, having a first phase of cubic boron nitride (cBN) particles and a ceramic binder phase with titanium compounds. The first phase occupies greater than 80% by volume of the self-sintered PCBN compact. The self-sintered PCBN compact has an electrical conductivity sufficient to be cuttable by electrical discharge machining.

摘要： Processes for high speed machining of workpiece materials using high performance tools with prolonged tool life and improved surface finish are provided by vibrating the tool and/or the workpiece at a frequency greater than the frequency of shear localization in the primary shear zone or chip segmentation occurring in the absence of tool vibration, with an amplitude sufficient to break up the tool-chip atomic contact, thereby decreasing the tool-chip contact length through decreasing the tool-chip contact time, thereby suppressing accelerated chemical tool wear caused by dissolution of the tool into the workpiece by nanocrystalline grain boundary diffusion and grain boundary sliding mechanisms by preventing shear localization associated with nanocrystalline grain formation in the primary shear zone of the chip, and suppressing oxidation wear of the tool by preventing segmentation of the chip.
