| Abstract: | Based on generally considering all important geometric factors during the forming of insider right-angle step on cross wedge rolling, accurate geometric model and mathematical model accorded with facts were built, and the shaping process of inside right-angle step was divided into three phases. Using the parameter equations of workpiece surfaces, volumes of shaping part on the workpiece in each phase are figured out. The accurate shaping curve of inside right-angle step of cross wedge rolling is gainedby using the volume fixedness theory. |
