| Research Abstract |
Workpieces of sugi, hinoki, makanba and honoki were orthogonally cut along the grain using tools with cutting angles of 30-90 degrees at undeformed chip thicknesses of 0.05-0.5 mm and a cutting speed of 10 mm/s. Movies of chip formation recorded with a high-speed video microscope and CT images of chips with a high-resolution X-ray scanner clearly showed the combinations of cutting angle and chip thickness for Type II chip formation and the boundaries between Types II and III chips, which are together called CHIJIMI-GATA in Japan. The application of digital image correlation to movies was also examined to measure cutting strains.
