摘要
采用微铣刀对芳纶纤维增强树脂基复合材料(AFRP)进行加工试验,对刀具磨损形式和形态进行系统研究,探索不同切削参数对刀具磨损的影响规律,分析微铣削AFRP时刀具磨损机理。结果表明:AFRP微铣削刀具主要磨损形式按顺序依次是刀尖破损、涂层脱落、磨粒磨损和工件材料粘结。切削速度对刀具磨损影响最大,刀具磨损量随切削速度的增大而增大,且随切削体积增加刀具磨损率越高,V_(c)=34.56m/min时可获得较小的刀具磨损和较高的加工效率;进给速度影响次之,刀具磨损量随进给速度的增大而减小,V_(f)=0.09m/min时刀具磨损较小;铣削深度对刀具磨损影响很小。
The micro-milling cutter is used to process aramid fiber reinforced plastic(AFRP)composite effect,the wear shape and wear form of tool are systematically studied,the influence of different cutting parameters on tool wear is explored,and the tool wear mechanism during micro-milling AFRP is analysed.The results show that the main wear forms of AFRP micro-milling tools are tool tip breakage,coating shedding,abrasive wear and workpiece material adhesion in order.Among the cutting parameters,the cutting speed has the greatest influence on tool wear.The amount of tool wear increases with the increase of cutting speed,and the tool wear rate increases with the increase of cutting volume.When V_(c)=34.56m/min,smaller tool wear and higher machining efficiency can be obtained;The feed rate is the second,and the tool wear decreases with the increase of the feed rate.When V_(f)=0.09m/min,the tool wear is small.Milling depth has little effect on tool grinding.
