摘要
航空工业中广泛使用薄壁结构零件 ,但是由于零件结构复杂、壁薄、精度要求高、加工工艺性差 ,在切削力、装夹力等因素的影响下 ,易发生加工变形 ,很难保证加工质量。由此 ,本文在有限元分析的基础上 ,提出了刀具偏摆数控补偿加工方案。实验结果证明 ,该方法可以在满足加工质量要求的同时 ,减少加工时间 ,提高加工效率 ,是一种方便、高效的加工方法。
Thin walled workpiece are widely used in aerospace industry. However, the workpiece expected with complicated structure, thin wall and high precision is easily deformed by the cutting and clamping force during machining. As the results of deformation,the required machining precision and efficiency are unable to reach. This paper presents a NC compensation approach of machining thin walled workpiece by tilting tools according to the FEM results.It is proved that this method can decrease machining time and increase efficiency. So it is a convenient method with high efficiency.
