RESEARCH ON CUTTING FORCE AND HOLE QUALITY DURING THE DRILLING OF KFRP COMPOSITES

Abstract

Abstract: KFRP composites have strong toughness which are therefore difficult to be processed. Different kinds of plates are used to investigate the efforts for the hole quality, and then single factor experiments are conducted to investigate the cutting force and hole quality in different working conditions. The cutting force, the tearing area and the fuzzing area are presented to analysis the cutting process and characterize the hole quality. The experimental results indicated that the plates can improve the hole quality, and the aluminum plates have the best efforts. There are close influences of feed speed and spindle speed on the cutting force and hole quality. The cutting force decreases with the spindle speed, and increases with the feed speed. The feed speed has a greater impact. Decreasing the axial cutting force can reduce the tearing and fuzzing area. The inside walls of the hole will be burned under low feed speed and high spindle speed working conditions.

Key words: KFRP composites, drill, force, tear, fuzz, burned wall
