This paper researched on automatic fiber placement path planning method based on mesh model.The busi-ness process of automatic fiber placement path planning was sorted out.A directional extension algorithm based on given points and directions was proposed,this algorithm was used to accurately calculate the points used for fiber placement paths on the mesh model.After equidistant offset curves,a point set optimization algorithm was proposed,which can avoid curve self-intersection and ensure curve accuracy.This paper analyzed the fiber compaction and roller deformation during the process of placement,and studied the path optimization method based on the analysis results.Combined with CATIA sec-ondary development platform,the automatic fiber placement path planning system was developed,and the feasibility of the method was verified.
