切削件结构设计准则（２）（十二）杨文彬（南京化工大学２１０００９）（续第６期）１引言在切削件结构设计准则（１）一文中，作者提出了四条切削件结构设计准则：便于退刀准则，减少加工量准则，可靠夹紧准则，同一夹紧工序准则。本文是上文的续篇，继续阐述切削件的... (12) 文 Yang Wenbin (Nanjing University of Chemical Technology 210009) (Continued on the 6th) 1 Introduction In the cutting structure design guidelines (1), the author proposed four cutting structure design guidelines : Easy to retract guidelines, reduce the amount of processing guidelines, reliable clamping guidelines, the same clamping process guidelines. This article is the sequel to the above, continue to elaborate on the cutting parts ...
