以某汽车地板下侧加强件为例,针对高强度钢拼焊板的回弹问题和传统检具测量所做回弹补偿的不足,提出了基于逆向工程技术并采用软件进行了回弹补偿。结果表明,传统检具测量与三维扫描测量值二者偏差在6%以内。三维扫描的点云数据可用于对零件回弹补偿计算,并用于加工修模。采用三维扫描所做的回弹补偿比传统检具检测效率和精度更高,并且可减少修模次数。
Taking the underside stiffener of a car floor as an example, aiming at the springback problem of high strength steel tailor welded plate and the lack of springback compensated by traditional gauge, a reverse engineering technology based on reverse engineering and spring back compensation was proposed. The results show that the deviation between traditional gage measurement and 3D measurement is within 6%. Point cloud data from 3D scanning can be used to compensate for part springback and be used for machining repair. The rebound compensation made by 3D scanning is more efficient and accurate than traditional gage inspection and can reduce the number of mold repairs.
