【期刊论文】Chip-ejection interference in cutting processes of modern cutting tools*
师汉民, SHI Hanmin
SCIENCE IN CHINA (Series E) June 1999 Vol. 42 No.3 275~281,-0001,():
-1年11月30日
Based on the "principle of minimum energy", the basic characteristics of non-free cutting are studied; the phenomenon and the nature of chip-ejection interference commonly existing in the cutting process of modem cutting tools are explored. A "synthesis m

【期刊论文】Bifurcation and Catastrophes in Metal-Cutting Processes*
师汉民, Hanmin Shi, , Xibing Wang, and Tao Lu
NOVEMBER 1998, Vol. 120 ,-0001,():
-1年11月30日
Based on a theoretical model and the Principle of Minimum Energy [1, 2, 3] the bifurcation and catastrophes in a non-free cutting process are theoretically predicted and experimentally verified. The phenomena lead to the complexity of a cutting process wi
