A thin-walled spherical shell made of pure iron material is a key part precision physical experiments. Tool wear characteristics freeform surface parts are significantly different from those single-point turning due to the movement contact point between tool and workpiece, which affects form accuracy integrity workpiece. However, there lack comprehensive understanding in machining materials. Th...

The bandsawing as a multi-point cutting operation is the preferred method for cutting off raw materials in industry. Although cutting off with bandsaw is very old process, research efforts are very limited compared to the other cutting process. Appropriate online tool condition monitoring system is essential for sophisticated and automated machine tools to achieve better tool management. Tool w...

The aim of this study is the modelling and analysis of tool wear on cryogenically treated CNMG120408SMRH13A inserts. Cryogenic treatment is carried out at -196°C for 48 hours, followed by tempering at 200°C for 2 hours. The AISI4340 steel is machined with cryogenically treated inserts by the turning process. Parameters, namely cutting speed, feed rate, and depth of cut, are selected as the inpu...

Wear of nonstandard involute gears with two types coatings, AlCrN and CrAlSiN, was studied. The coatings were applied by cathodic arc deposition. tested using a Niemann tester at graduated load up to the 12th stage compared noncoated gears. Both Biogear S150 gear oil PP90 universal hydraulic during these tests. thickness deposited wear teeth studied SEM their chemical compositions determined ED...

For the sake of improving benefit enterprise by reducing energy waste. RSM (response surface methodology) was used to investigated cutting power wood–plastic composite at different conditions (rake angle, speed, depth cut, and flank wear). Based on experimental results, a model with high degree fitting developed, which can be predict optimal conditions. Meanwhile, effects rake wear their intera...

Strenx 1100 structural steel has unique material properties enables to utilize in important engineering applications such as marine and heavy vehicles. Due the surface integrity of parts produced by this is paramount importance, tool wear condition needs be considered well. As being applicable easy measure, flank (VB) widely preferred field reflects remaining life. Minimum quantity lubrication ...

The present paper describes the geometries of honing wheels used in final tooth-flank-finishing process automotive transmission gears. For micro honed gears to keep their required gear accuracy, improper a gear-honing wheel cause dressing interval be short. That is because stock removals are not uniform over tooth flank, then wear also uniform. As result, out tolerances. amount removal could de...

Despite the fact that Titanium material has been considered as difficult to cut material, its usage has been increasing day by day in all engineering sectors; wherever criticality is encountered. Many studies are going on in view of increasing tool life at high cutting speed to improve productivity. In this study, attempt has been made to see the effect of iron as a partial substitution  along ...
