| Abstract: | In order to turn the revolving surface formed by cubic NURBS curve,this paper introduced the G1 continuity conditions and G2 continuity conditions,and discussed the method to create the mathematical expressions of the cubic NURBS curve by the G1 continuity conditions and G2 continuity conditions.According to the mathematical expressions of the cubic NURBS curve,we programmed the finish turning NC programs of the revolving surface.By turning verification actually in CK6132 lathe with CNC and comparing with t... |
