文摘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 modern cutting tools are explored. A “synthesis method of elementary cutting tools” is suggested for modeling the cutting process of modern complex cutting tools. The general equation governing the chip-ejection motion is deduced. Real examples of non-free cutting are analyzed and the theoretically predicted results are supported by the experimental data or facts. The sufficient and necessary conditions for eliminating chip-ejection interference and for realizing free cutting are given; the idea and the technical approach of “the principle of free cutting” are also discussed, and a feasible way for improving or optimizing the cutting performance of modern cutting tools is, therefore, found.
