The Radome NC Machining System-Establishment of the Mathematical Models

DU Fan LIN Bin (Key Laboratory of Advanced Ceramics And Machining Technique,TianJin University,State Education Ministry,Tianjin 300072,China)  
The radome made of special ceramic is a workpiece needed to be machined precisely. The machining precision of the exterior contour of the workpiece effects the performance of the radome directly. Considering the characteristics of the special numerical control grinder, such as 3--axis simultaneous motion and linear exterior contour, it introduced three parameters(L, b, a)and modeled the mathematics model of the trochoid of the knife rest cireumgryrating center in this thesis. According to the mathematics model, although the numerical control grinder machining the same curve ever- y time. the troehoid of the knife rest eircumgyrating center may be different. With the help of software MATLAB. pro- grams have been programmed to check up the correctness of the mathematics model.
