Investigation on influence of hybrid nozzle of CryoMQL on tool wear, cutting force, and cutting temperature in milling of titanium alloys

Autor: Gil Sang Yoon, Dong Wook Lim, Jeong Yeon Park, Ki Hyeok Song, Seok Jae Ha

Publikováno v: The International Journal of Advanced Manufacturing Technology. 110:2093-2103

The titanium alloy has a low thermal conductivity of 1/8th that of common metals and half that of stainless steel. The heat dissipation is poor during dry cutting, so the cutting temperature rises above about 600°C. Due to this, the quality of the c

Magnetorheological fluid polishing using an electromagnet with straight pole-piece for improving material removal rate

Autor: Myeong Woo Cho, Jae Hwa Chung, Byung Chan Kim, Seok Jae Ha, Gil-Sang Yoon

Publikováno v: Journal of Mechanical Science and Technology. 32:3345-3350

Mechanical grinding techniques can cause residual stress, micro-cracks, and work hardening in workpieces. Processes employing magnetorheological (MR) fluid aim to reduce subsurface damage by avoiding the direct application of mechanical force. Howeve

Effect of pre-treatment polishing on fabrication of anodic aluminum oxide using commercial aluminum alloy

Autor: Seok Jae Ha, Byung Chan Kim, Myeong Woo Cho, Ki-Beom Kim

Publikováno v: Journal of Mechanical Science and Technology. 31:4387-4393

Aluminum anodizing is a process in which metal is oxidized with an electrochemical method to make a metallic oxide. Because it can be used to manufacture an Anodic aluminum oxide (AAO) with dozens to hundreds of nanoscale pores that are vertically an
