The Fast Moulding Technology of NC Unit Punching Die

In the paper we introduce the digital coding of the fast moulding of a unit die which is based on elementary shape assembling and the structure sketch drawing of NC unit die.We alse present the control system design of the unit die which adopt AT89c52 single-chip computer and the system program frame which base on VB6.0 and the communication program block diagram between upper compter and single-chip compter in detail.
