In the milling process, under high-efficiency and intermittent cutting loads, instantaneous posture of cutter cutter-workpiece engagement are in an unstable state. It is difficult to accurately identify friction wear boundary tooth flank. has become urgent problem be solved life evaluation cutters. The characteristics variation distribution thermal-stress mechanical coupling field flank vibrati...

Hard turning of martensitic stainless steel is gaining importance in all manufacturing sectors like automobile and aerospace industries. Machinability of materials depends on surface roughness, tool wear, cutting forces, specific cutting pressure and work material hardness. In this research hard martensitic stainless steel AISI 440 C and SCM 440 alloy steel was used as work materials. CBN and P...

Machining of carbon fibre reinforced polymer (CFRP) is abrasive and causes significant tool wear. The effect wear on static flexural strength investigated, using edge trimming with uncoated carbide chemical vapour deposition (CVD) diamond coated burr style tools. Edge rounding (ER) criteria along flank are used to observe degradation ER shown preferentially allowing the become cyclically sharpe...

Parameter estimation for trending analysis is a generic problem with broad applications. In manufacturing, trending analysis can be applied to tool wear estimation, which not only affects the tool life but also and the quality of a machined product. Consequently, in-situ tool wear monitoring and remaining tool life prediction play a significant role in ensuring precision and cost-effective manu...

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...
