扇形板截形数据的逆包络法求解

Extraction of Fan-shaped Section with Adverse Envelope Method

依据扭制钻头工艺 ,建立了相应的数学模型 ,采用逆包络法求得扇形板截形数据 ,并用圆弧拟合以符合工厂生产的生产实际 .

Based on the study of the technique of twist-forging drills in factories,a corresponding mathematical model is set. The inverse envelope method can be used to extract the numerical value of the section of a fan-shaped. The arc joining method is adopted to accord with the production in factories.
