简介：汽车前轴属大型长杆类锻件．由于锻造、热处理的加热和冷却产生应力的原因．容易导致前轴变形，热处理后锻件的长度、落差和主销头倾角都会发生变化。从而影响机加工．产生大量废品。所以需要对热处理后的前轴锻件进行100％的在线检测，判断其是否有充足的加工余量，不合格的进行人工返工校正。这种检测依靠配专用检具和人工划线的方法如图1所示，操作繁琐．基准不确定，劳动强度大，且准确率低，通常会有20％～30％的误判需要再次返工校正。所以前轴冷校正在线检测一直是行业中亟待解决的难题。

简介：蒙皮是构成飞机气动外形的外表零件．其尺寸大、品种多、外形复杂、批量小．主要采用拉伸成形（简称拉形）工艺．其先进程度是衡量一个国家飞机制造能力和水平的重要标志。
