Abstract:  The shapes of the initial blanks and the final products are quite different in the complex curved surface machining for some brittle materials, such as natural stone and artificial crystal. The large removal of rough machining material leaded to the low processing efficiency and serious tool wear. A new solution was proposed based on the cooperative removal of wire saw cutting and point-cutting for the high-efficiency rough machining. According to the characteristics of wire saw processing, a new modeling method was proposed herein. The digital model of final product was layered, the polygons were used to envelope the two-dimensional outer contour curves of each layer, a ruled surface model was established with fitting the polygons between the layers. The influences of different ruled surface models constructed by different envelope polygon sides and connection methods on roughing processing time were analyzed. The simulation results show that although increasing the numbers of polygon sides or rotating between layers may reduce the volumes of remaining unprocessed materials, the overall rough machining time increases, which is not conducive to improving efficiency. The rough machining time may be used as a comprehensive evaluation index to optimize the construction of the ruled surface model.
