Polycrystalline diamond (PCD) tools are widely used in industry due to their outstanding physical properties. However, the ultra-high hardness of PCD significantly limits machining efficiency conventional abrasive grinding processes, which utilized manufacture tools. In contrast, electrical discharge (EDG) has higher because its unique material removal mechanism. this study, quality and perform...

This paper presents some important, recently performed investigations on the laser texturing technology applied to PCD and PCBN cutting tools resulting process outputs including forces, tool wear indexes concerning both rake flank faces. It was documented that properly texturized faces results in a substantial reduction of elimination adhesion interaction between chip, abrasive diffusion wear. ...

An attempt has been made to investigate the machinability of zirconia toughened alumina (ZTA) inserts while turning AISI 4340 steel. The insert was prepared by powder metallurgy process route and the machining experiments were performed based on Response Surface Methodology (RSM) design called Central Composite Design (CCD). The mathematical model of flank wear, cutting force and surface roughn...

In a modern machining system, tool condition monitoring systems are needed to get higher quality production and to prevent the downtime of machine tools due to catastrophic tool failures. Also, in precision machining processes surface quality of the manufactured part can be related to the conditions of the cutting tools. This increases industrial interest for in-process tool condition monitorin...

Tool runout, cutting edge radius-size effect, and tool wear have significant impacts on the force of micro-milling. In order to predict micro-milling related performance, it is necessary establish a model including radius, wear. this study, an instantaneous uncut chip thickness (IUCT) considering nonlinear shear/ploughing coefficient cutting-edge friction embedded with flank width are respectiv...

A new prediction method was proposed based on the positive feedback relationship between tool geometry and wear rate. Dry orthogonal cutting of Inconel 718 used as a case study. Firstly, rate models flowchart were proposed. Secondly, evolution during analyzed considering combined effect crater flank wear. Thirdly, temperature, normal stress tool–chip relative sliding velocity surface studied, r...

Hard turning with cubic boron nitride (CBN) tools has been proven to be more effective and efficient than traditional grinding operations in machining hardened steels. However, rapid tool wear is still one of the major hurdles affecting the wide implementation of hard turning in industry. Better prediction of the CBN tool wear progression helps to optimize cutting conditions and/or tool geometr...
