Abstract：In order to assess the operating performances of 7 degrees of freedom ( DOF) automated fiber placement robotic in fiber tow placement process, the performance indexes were proposed, which contained condition number and operability. The proposed performance indexes were optimized by Ada Boost algorithm, and the optimal weighting coefficient was obtained, then the performance index function was determined. The determined performance index function was used to simulate on 7-DOF automated fiber placement robotic operation. The results showed that the proposed performance indexes could satisfy the flexibility and operational ability of the robot.
