Effect of Machining Conditions on Temperature and Vickers Microhardness of Chips during Planing

Metals, 2022
For the machining of long and narrow surfaces and when processing multiple pieces, planing technology is used, the productivity of which can be higher than that of milling, although it is relatively slow machining. The article aims to study the degree of

Influence of Cutting Conditions on the Cutting Performance of TiAl6V4 [PDF]

Advanced Materials Research, 2011
The FEM simulation was developed to investigate the influences of cutting speed, uncut chip thickness and tool rake angle on the cutting performance of TiAl6V4. The FEM simulation was validated using experimental results and good agreement was obtained.
