1. Analysis of Al2O3-ZrO2 ceramic insert in turning process of Ti-6Al-4V alloy using grey Taguchi-based response surface methodology (GT-RSM)
Abstract The present investigation aimed at a sustainable green turning operation of Ti-6Al-4V alloy using multi-objective optimization of surface roughness, tool flank wear, material removal rate, and tool wear loss with cutting speed, feed rate, and depth of cut as input parameters. The experiments were performed on a CNC lathe machine using an alumina-zir

2. The influence of contact stress distribution and specific film thickness on the wear of spur gears during pitting tests
One of the main gear damage mechanisms is the formation of pitting and spalling on the tooth flank. Several factors have significant influence on the damage formation, such as: contact stress level; tooth profile type; relative contact speed; surface finish and lubrication conditions. This work comprehends the global observation of all such parameters and wa

3. Wear evaluation of WC inserts coated with TiN/TiAlN multinanolayers
TiN/TiAlN multilayers were deposited by radio frequency, r.f., reactive magnetron sputtering by using titanium and aluminum targets with 10 cm diameter and 99.99% purity in an argon/nitrogen atmosphere, applying a substrate temperature of 300 ºC. WC inserts were used as substrates to improve the mechanical and tribological properties of TiN/TiAlN multilayer

4. Estudo da usinabilidade dos ferros fundidos cinzentos ligados (CrCuSn e CrCuSnMo) e vermicular classe 350 no fresamento frontal em alta velocidade de corte
Cast iron is used to manufacture engine blocks due to its mechanical and physical properties like thermal conductivity and dumpy capacity, which are fundamental to these applications. Compacted graphite iron (CGI) has higher mechanical strength compared to gray cast iron and can be a great advantage in these type of mechanical parts. The compression rate can

5. Surface topography assessment techniques based on an in-process monitoring approach of tool wear and cutting force signature
One of the most influential sources in machining affecting surface roughness is the instantaneous state of tool edge. The main objective of the current work is to relate the in-process immeasurable cutting edge deformation and surface roughness to a more reliable easy-to-measure force signals using a robust non-linear time-dependent modeling regression techn

7. Evaluation of the performance of different nano-ceramic tool grades when machining nickel-base, inconel 718, alloy
High-speed machining of aerospace alloys can be enhanced by the use of advanced cutting tool materials such as nano-grain size ceramics that exhibit improved physical and mechanical properties than their micron grain counterparts. The performance of recently developed nano-grain size ceramic tool materials were evaluated when machining nickel base, Inconel 7

8. Influence of Cutting Conditions on Tool Life, Tool Wear and Surface Finish in the Face Milling Process
The main goal of this work is to study the influence of cutting conditions - cutting speed, feed velocity and feed per tooth - on tool life and surface finish of the workpiece in the face milling of flat surfaces. Aiming to achieve this goal, several milling experiments were carried out with different cutting speeds, feed velocities and feeds per tooth. In t

9. Investigation on diamond turning of silicon crystal - generation mechanism of surface cut with worn tool
This paper discusses the effect of tool wear on surface finish in single-point diamond turning of single crystal silicon. The morphology and topography of the machined surface clearly show the type of cutting edge wear reproduced onto the cutting grooves. Scanning electron microscopy is used in order to correlate the cutting edge damage and microtopography f
