A Study on Fracture Behavior of Brazed Multicrystalline CBN Abrasive Grains During Grinding
This paper analyses the fracture behavior of the brazed BCBN grain by comparison with brazed PCBN grain through grinding test of Nickel-based superalloy. The self-sharpening effect is created by timing micro-fracture behavior for BCBN abrasive grains, but by macro-fracture behavior for PCBN abrasive grains. During grinding with brazed BCBN abrasive grains, the material is removed together with ...
متن کاملInvestigation of Surface Roughness and Flank Wear by CBN and PCBN Tools on Hard Cr - Mo Steel
Hard turning is the latest technology and is used to turn hard materials by using cutting tools like CBN and PCBN. Certain hard materials like titanium, Inconel and stainless steel are pronounced as difficult to cut materials. The superior cutting tools effectively machine such hard materials and produces desirable surface roughness with less tool wear. The present research was carried on hard ...
متن کاملPCBN Tool Wear for Hard Materials Based on Thermodynamics Principals
The temperature rise exceeds over 1000°C in cutting process while working with PCBN tools high speed machining. This intense temperature results in wearing of tools and thus diffusion and oxidation are mainly responsible for wearing. This paper proposes the oxidation and diffusion wearing for PCBN cutting tools and analysis has been carried out considering thermodynamics principles. The next st...
متن کاملHard turning with variable micro-geometry PcBN tools
This paper presents investigations on hard turning with variable edge design PcBN inserts. Turning of hardened AISI 4340 steel with uniform and variable edge design PcBN inserts is conducted, forces and tool wear are measured. 3D finite element modelling is utilized to predict chip formation, forces, temperatures and tool wear on uniform and variable edge micro-geometry tools. Predicted forces ...
متن کاملCrack separation mechanism applied in CO2 laser machining of thick Polycrystalline Cubic Nitride (PCBN) tool blanks
The main objectives of this work are: (1) to explore and improve the hybrid CO2 laser/waterjet (LWJ) technique, developed by Iowa State University’s Laboratory for Lasers, MEMS and Nanotechnology, to machine thick polycrystalline cubic boron nitride (PCBN) tool blanks both in 1D and 2D with minimum energy consumption and good cut quality; (2) to examine the mechanism of crack separation in the ...
