High Speed Finish Turning of Inconel 718 Using PCBN Tools under Dry Conditions

Metals, 2018
Inconel 718 is a superalloy, considered one of the least machinable materials. Tools must withstand a high level of temperatures and pressures in a very localized area, the abrasiveness of the hard carbides contained in the Inconel 718 microstructure and

The Influence of PCBN Inserts Microgeometry on Cutting Forces, Surface Roughness, and Tool Wear When Milling Inconel 718

Advances in Mechanical and Materials Engineering
This study investigates the effect of cutting edge microgeometry on the milling of Inconel 718, a superalloy widely used in aircraft engine components. Face milling tests were conducted using a Ø63 mm tool with unevenly distributed polycrystalline cubic ...

Fracture behavior and self-sharpening mechanisms of polycrystalline cubic boron nitride in grinding based on cohesive element method [PDF]

, 2018
Unlike monocrystalline cubic boron nitride (CBN), polycrystalline CBN (PCBN) shows not only higher fracture resistance induced by tool-workpiece interaction but also better self-sharpening capability; therefore, efforts have been devoted to the study of ...
