TOOL PATH POSTURE OPTIMIZATION FOR COMPOSITE AUTOMATED FIBER PLACEMENT

Abstract

Abstract: In order to improve the manufacturing efficiency of Automated Fiber Placement (AFP), a posture optimization algorithm, which based on High Speed Manufacturing research, is proposed. During AFP manufacturing, due to the unfairness of orientation change, servo motors are required to accelerate and decelerate frequently to meet the manufacturing orientation requirements, which limits the process rate. In order to increase the efficiency, according to the flexibility of the rubber roller, the admissible orientation domain based on the roller coordinate system is established. Under the constraint zone, the rotation curve is optimized by Butterworth digital filter and objective optimization function, which contributes to the increasement of manufacturing efficiency. According to data analysis and practical placement experiment, the optimized tool path has a better fairness property in rotation axis motion and acceleration curve. Besides, the manufacturing efficiency has been improved compared with the original two paths.

Key words: automated fiber placement, tool path optimization, manufacturing efficiency, domain of admissible orientation
