The processing technique improvement on launcher with abnormity figureHU Ningqiang①，WANG Li②(①China Airborne Missile Academy，Luoyang 47 1009，CHN；Luoyang Dongfang Senior Middle School，Luoyang 47 1009，CHN)Abstract：The launcher with abnormity figure often oversteps the contour dimension when it is processed.To re·solve the problem，through analyzing the processing technique，the paper gives a technique improvementproject.Through adjusting technique route，making tools，the products qualifed rate is improved。

Keywords：The Launcher with Abnormity Figure；Processing Technique Improvement；Qualifed Rate多型空空导弹发射装置壳体均为异型壳体，该零件形体大、加工工序复杂、加工周期长。在该零件的加工中，经常发生零件轮廓尺寸超差现象，影响产品的合格率，
