To recommend one suitable tool material for the cutting of marine steels under special conditions and requirements in emergency rescues capsized steel ships, cermet tools, cemented carbide tools coated were evaluated using a fuzzy evaluation method concerning force, temperature, surface roughness wear. Experimental results indicate that performance was diverse difficult to evaluate with single ...

The current experimental study is to investigate the effects of process parameters (cutting speed, feed rate and depth of cut) on performance characteristics (surface roughness, machining force and flank wear) in hard turning of AISI 4340 steel with multilayer CVD (TiN/TiCN/Al2O3) coated carbide insert. Combined effects of cutting parameter (v, f, d) on performance outputs (Ra, Fm and VB) are e...

Currently, manufacturing industries focus on intelligent manufacturing. Prediction and monitoring of tool wear are essential in any material removal process, implementation a condition system (TCMS) is necessary. This work presents the flank prediction during hard turning EN8 steel using deep learning (DL) algorithm. The operation conducted with three levels selected parameters. CNMG 120408 gra...

Abstract The dry machining strategy has recently received high attention in the field of metal cutting as it can eliminate environmental impacts associated with usage fluids. However, high-generated heat and severe tool wear are usually observed for operations. One suggested techniques to improve performance is utilize textured tools, reducing friction at chip-tool interface. In this study, thr...

This research work focuses on the experimental investigations conducted using uncoated cBN tool and (AlCrN) PVD Coated for turning Inconel 718. Two different sets of experiments – one with another coated inserts were considering three levels cutting speeds, feed rates depth cuts. The performance over evaluated it was found that AlCrN can produce 10-12% drop in force, 15% reduction flank wear 10...

In industrial production systems, including the most important factors in the economic field machining operations, reduce tool wear due to abrasive nature of the phenomenon on many factors, including temperature Lathe tool, influences, machining conditions (cutting speed, speed losses, forcing to rebuild parts of the manufacturing tolerances disassemble tool wear is caused by the phenomenon, as...

Machining of hard materials is a recent technology for direct production of work-pieces. The primary challenge in machining these materials is selection of cutting tool inserts which facilitates an extended tool life and high-precision machining of the component. These materials are widely for making precision parts for the aerospace industry. Nickel-based alloys are typically used in extreme e...

This study presents an intelligent system for online tool condition monitoring in drilling process .In this paper, analytical and empirical models have been used to predict the thrust and cutting forces on the lip and chisel edges of a new drill. Also an empi...

Hard turning has been proved 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 its wide implementation in industry. Better modeling of the tool wear progression helps optimize cutting conditions and/or tool geometry to reduce tool wear, which can make hard turning a feasible ...
