The quality of a machined surface is becoming more and more important to justify the increasing demands of sophisticated component performance, longevity, and reliability. Usually, any machining operation leaves its own characteristic evidence on the machined surface in the form of finely spaced micro irregularities (surface roughness) left by the associated indeterministic characteristics of t...

Direct machining steel parts at a hardened state, known as hard turning, offers a number of potential benefits over traditional grinding in some applications. In addition, hard turning has several unique process characteristics, e.g., segmented chip formation and microstructural alterations at the machined surfaces, fundamentally different from conventional turning. Hard turning is, therefore, ...

The friction contact boundary between the tool flank of milling cutter and machining transition surface is important indicator to reveal third deformation zone relationship assessing frictional wear performance cutter. existing models for identification pay attention maximum width accumulated on flank, ignoring variability overall local morphology flank. Aimed at influence vibration instantaneo...

Instantaneous friction and wear energy density are important indicators of the state tooth flank milling cutter. Existing methods for identifying on cutters mainly focus overall level consumption maximum width accumulated teeth flanks, ignoring unevenness variability volume distribution tool flank, dynamic relationship between instantaneous each cutter is to be revealed. Transient cutting posit...

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. ...
