Abstract
Edge preparation is a process to modify edge geometry and surface integrity of cutting tools. Edge preparation experiments of tungsten carbide cutting tools were carried out through an abrasive nylon brushing method. Tools wear and cutting temperatures with different edge radius were simulated with FEM software. The experimental results show that cutting edge defects were eliminated through brushing edge preparation. The edge radius has influences on cutting tool performance. When the edge radius is 20μm, the least wear can be obtained. Then tool wear value increases with the edge radius. A suitable edge radius will have a reasonable cutting temperature distribution. The tool temperature distribution shows the same results as tool wear. A suitable edge radius range is needed for edge preparation and a reasonable edge radius is needed to improve tool life.
