... properties are adopted to study their rheological and machining performances in the designed flow channel with a contraction area. The rheological properties are tested by frequency sweep and characterized by the Maxwell viscoelastic model and the Carreau viscous model. In the experiment, the variation...

... the machining performance of new generation near-beta alloys, namely, Ti-5553, by focusing on a high-speed cutting process under cryogenic cooling conditions and dry machining. The machining experiments were conducted under a wide range of cutting speeds, including high speeds that used liquid nitrogen (LN 2...

...Chandra Nath; Shiv G. Kapoor; Anil K. Srivastava; Jon Iverson As seen from the results of turning experiments in Sec. 3.2 , the machining performance such as tool life and surface quality are found to improve with the increase in droplet velocity and the decrease in gas velocity. A higher...

..., and electrical parameters on the machining performance, as well as surface quality and accuracy of the microholes have been investigated. It has been found that the overall machining performance improves considerably with significant reduction of machining time, increase in MRR, and decrease in EWR. The improved...
