摘要
Abstract
In order to ensure the processing quality of carbon fiber reinforced resin matrix composites(CFRP),the effect of tool wear on the hole quality of CFRP is studied.By making CFRP laminates,the relationship between tool wear law and hole quality of CFRP materials is quantitatively studied.The tool wear curve is drawn by tracking the wear amount VB of the rear cutter face in the process of marking the customized hole with a digital microscope,and the wear law of the rear cutter face under different rotating speeds is quantitatively compared and analyzed.At the same time,the length and stratification of outlet burr are calibrated by experiments.The quality of the drilled hole is evaluated by the exit burr defect factor and the hole processing delamination defect factor respectively.The correlation curve of defect factor and VB was drawn.Quantitative analysis was made on tool wear factors and their impact on drilling quality.The experimental results show that the cutting tool enters the high-speed wear stage quickly at high speed.In the high-speed wear stage,the tool wear is faster at low speed.After the tool enters the stage of high-speed wear,tool wear gradually becomes the main cause of outlet defects,and the quality of hole making is higher at high speed when the tool wear amount is the same.关键词
