摘要
放电加工领域的相关专利文献量大,而相关的IPC分类细分不足,需要不断调整关键词检索,检索效率低。在该领域中,日本专利文献量占比较大,FT分类给出了足够的细分。实际应用表明,利用FT分类进行检索具有显著的优势,浏览方便,检索效率高,可为FT分类在放电加工领域高效检索提供一定的借鉴和参考。
There is a large amount of related patent literature in the field of discharge machining,and the relevant IPC classification and subdivision is insuffcient,which requires constant adjustment of keyword retrieval and low retrieval efficiency.In this field,Japanese patent literature accounts for a large amount,and FT classification provides sufficient subdivision.Therefore,this paper provides certain references for efficient retrieval of FT classification in the field of discharge machining through practical cases.
