Analysis of Tool Wear Behavior of Single Crystal Diamond Based on FEM Simulation in Micro Turning
Autor: Seok-Woo Lee, Dong Yoon Lee, Sung Ho Nam, Ki Hyeong Song, Kyung Hee Park
Publikováno v: Advanced Materials Research. :811-819
Micro turning test was performed on nickel plated roll die using ultra precision lathe and lenticular shape single crystal diamond (SCD) tools. For the test, fresh tools were used for each experiment to observe tool wear evolution at the cutting dist

Experiment-based statistical prediction on diamond tool wear in micro grooving NiP alloys
Autor: Su-Jin Kim, Ki-Hyeong Song, Dong Yoon Lee, Seok-Woo Lee, Duy Le
Publikováno v: Diamond and Related Materials. 41:6-13
Diamond tool wear in grooving micro patterns on nickel alloys has caused an increase in the pattern geometry defect rate over time. Therefore, it is important to be able to understand and predict diamond tool wear and tool life. However, as experimen
