摘要
针对螺旋铣孔与传统钻孔刀具磨损的问题,对CFRP/Ti叠层材料进行螺旋铣孔与传统钻孔试验。在相同加工效率及切削速度的基础上,对两种工艺加工孔的切削力及刀具后刀面磨损长度进行了测量。结果表明:制孔过程中,螺旋铣削制孔的切削力明显小于钻削制孔的切削力;加工过程中,螺旋铣削制孔的切削力比钻削制孔的切削力更加平缓;同等参数条件下,螺旋铣削加工到24孔时刀具失效,传统钻削加工到18孔时刀具失效;螺旋铣削制孔的刀具比钻削制孔的刀具更加耐磨,加工孔数更多。
According to the wear of cutting tool in helical milling and traditional drilling,the experiments are carried out on CFRP/Ti laminated materials by helical milling and traditional drilling test. On the basis of the same processing efficiency and cutting line speed,the cutting force and the length of tool flank wear are measured in the two kinds of machining holes process. The results show that the cutting force of the helical milling is obviously smaller than that of drilling hole.During the machining process,the cutting force of the helical milling is more gentle than the cutting force of the drilling.Under the same parameters,the tool is failed when the helical milling is done to 24 holes,and the tool is failed when the conventional drilling is done to 18 holes. The tool of the helical milling is more wear-resistant than the drilling tool,and the number of machining holes is more by helical milling.
