Edge Blunting of Hard Alloy Cutter Blade for Cutting chemical fibers

Journal of Donghua University(English Edition) 2006年第2期23卷 26-30页

作者：原一高朱世根 College of Mechanical Engineering Donghua University

Through the establishment mathematical model and experimental verification, the course of blunting of hard alloy cutter blade for cutting chemical fiber have been studied. The result shows that the cutter blade sharpness would be greatly reduced in the course of fiber cutting as the initial edge radius and edge angle, the linear wear, and the notch depth of cutter blade are increased. The blunting of cutter blade in the course of fiber cutting can be divided into four stages. The reducing degree of the sharpness is different in different stages. The linear wear of cutter blade is almost negligible. The blunting of the cutter blade is directly related to the depth of notches generated on the cutting edge. The deeper the notch, the more the cutter blade sharpness would be decreased.

Science is the basis of the country’s development and wealth. In particular, it is necessary to effectively use advanced scientific developments and technical achievements in order to strengthen the economy in the period when the desire for innovation in all fields is still growing. In theoretical-experimental Scientific Research work, both theoretical and experimental results are achieved, and it is more useful to withstand more theoretical-experimental loads for a longer period of time. The occurrences in the production process of natural wool fiber technologists are a complex of physical and mechanical phenomena, which can be used only by the modern achievements of science and technology. In most cases, the parameter relationship with the factors influencing the technological process or the object can open a curve without any other things.
