摘要
根据叶片螺旋铣专用夹具结构,以工程力学理论对叶片简化模型进行弯扭变形规律分析,计算得出弯扭变形量与叶片宏观几何参数的对应关系,并且预测了叶片发生最大加工变形的区域,为数控编程提供可靠的工艺性分析工具。
Appearance of blade is approximated by box which has three important dimensions: length, thickness and section chord, this simplified model is used for elasticity analysis. According to the special technological clamp used in blade spiral NC programming, formula of elasticity along section and guiding curve is deduced, max-elasticity area on blade surface is also forecasted, which may be useful in technology optimization.
