摘　　要：根据曲线曲率计算公式和三次Bezier曲线的表达式,推导建立了三次Bezier曲线的曲率计算公式,结合图形图像软件CorelDraw12导出AI字体文件中曲线的类型,具体表达了Bezier曲线曲率公式在新型围字机设备中的应用,对围字机围弧加工进行了改进,使加工出的轮廓字达到圆滑美观效果。According to the calculation formula of the curvature and the mathematical expression of cubic Bezier curves, the mathematical expression of cubic Bezier curvature is established. And combined with the type of curves in AI format files of CorelDrawl2, the application of Bezier curve＇s curvature in the bending machine is discussed. This article improves the process for arc-making. As result, the products are smooth and handsome, very satisfying.
