曲面薄壁工件加工工艺探索

Exploration on Processing Thinwall Camber Parts

航空航天产品中常用曲面薄壁零件,多年来,这类产品的加工一直采用人工旋压和开模冲压的方法,但这两种方法在实际操作过程中都存在不足。为克服以上两种方法的不足,对薄壁曲面工件的加工可以利用数控车床的优点,通过调整程序、调整刀具的几何角度、选择合理的切削速度和走刀量解决车削薄壁特型曲面工件的难题。

Tbinwall camber parts of aerospace product have always been manufactured by means of manual spinning and pressing equipment, which have its disadvantages. Aiming at the problem rising in practical manufacture, this paper introduces the processing technology of the CNC turning which involves adjusting the parameters of the NC program and geometry parameters of the lathe tool, rational selection of cutting parameters such as the cutting speed and amount of feed.
