【Abstract】 Cutting edge geometry is crucial to the tool life and performance. An appropriate geometry of the cutting edge improves the tool wear resistance,then the tool life and the process reliability. Cutting edge geometry includes macro geometry and microgeometry and its micro topography. Defined and specific microgeometry and microtopography can be obtained with an appropriate edge preparation process. Cutting edge preparation technologies and methods,characterization and measurement methods are reviewed. Influences of cutting edge geometry on the cutting tool properties,cutting behaviors,cutting tool wear resistance,tool life and performance are discussed.更多还原
