NC Application in Rolling Machining of Special Section Tube
The special section tube was machined by special NC reconstruction according to constituents of rolling motion. The rotation of driving and driven roller was controlled directly by servo motors and the rolling machining was controlled by converting linear motion into rotary motion. The principle, control and implementation and the analysis of the bending deformation regularity and influencing factors affecting the uniformly accelerated motion and measures were elaborated. The structural reconstruction and the parameters conversion and the reason why the machining accuracy improved were analysizedanalyzed. The NC reconstruction in rolling machining of the special section tube had good effects on the practical application and the function and application scope of NC technology were expanded
