新型微槽刀具的切削能及刀具耐用度研究
|
摘要
针对切削难加工材料时刀具耐用度较低的问题,提出基于温度场理论的刀具切削刃近域微槽设计方法。以某企业加工高温合金的刀片为基体,在其前刀面设计一个微槽,通过单因素试验研究切削参数对切削能的影响规律,结果表明采用较大的进给量和切削深度所消耗的切削能越少;此外,在推荐的切削参数下,原刀片的切削温度和切削能均大于微槽车刀,但是原车刀的剪—总能比小于微槽车刀,且微槽车刀的耐用度提高了21. 4%。试验结果表明,微槽的设计不仅改变了刀具切削能的产生和分布,而且提高了刀具的耐用度,对长寿命刀具的设计具有重要意义。
In view of the poor durability of tool during machining hard materials,a new design method of micro-groove near cutting tool edge is proposed based on temperature field theory. A micro-groove is designed in the rake face of a commercial cutting tool machining superalloy. The effect of cutting parameters on the cutting energy is studied by experiments,and the results show that the less cutting energy consume,the larger the feed rate and depth of cut are. Besides,with cutting parameters recommended by the manufacturer,the cutting temperature and cutting energy of the original cutting tool are larger than that of the micro-groove tool,but the ratio of shear-total energy of the original tool is smaller than that of the microgroove tool. Meanwhile,the durability of the micro-groove tool is improved by 21. 4%. The results show that the design of micro-groove not only changes the generation and distribution of cutting energy,but also improves the durability of tool,which is of great significance for the design of long-life cutting tool.
