This paper compares the performances of uncoated carbide and coated cermet inserts for
varied machinability aspects throughout the machining of hardened steel (AISI 4340, 48 …

Tool wear and surface roughness as performance indexes are considered to be the most
important in terms of hardened materials' machinability. The best combination of cutting …

In the present work, effect of work material hardness and cutting parameters on chip-tool
interface temperature was investigated during turning of AISI 4340 steel hardened at two …

Precision hard machining is an interesting topic in manufacturing die and mold, automobile
parts, and scientific research. While the hard machining has benefit advantages such as …

Belonging to the class of chromium tool steels, AISI H11 possesses very good toughness
and hardness, and is therefore suitable for hot metalforming jobs performed at very high …

Wear investigation has been conducted on mixed ceramic cutting tool (70% Al2O3+ 30%
TiC) when machining hardened AISI 52100 steel (66 HRC). Experimental planning method …

To neutralize the effect of cutting parameters, a combination of parameters such as cutting
speed, feed rate and depth of cut to be used in the experimental tests is selected from the …

A type of Si 3 N 4/TiC micro-nanocomposite ceramic cutting tool material was fabricated
using Si 3 N 4 micro-matrix with Si 3 N 4 and TiC nanoparticles. Cutting performance of the …

This research focused on wear analysis by using the coefficient of friction (COF) and high-
speed CNC turning machine against ceramic cutting tools made from 80 wt.% Al 2 O 3-20 …

Le but des industriels aujourd'hui est d'abaisser au maximum les coûts des opérations
