Abstract:

As one of the key issues for machining path control of fiber placement molding, trajectory planning directly influences the molding accuracy and placement efficiency of composite structures. To obtain the machining path for deal with, the CATIA numerical control programming soft is used to calculate the fiber placement trajectory. The problem of poor compatibility between placement trajectory information and FANUC is solved by using the vector supplement and format conversion algorithm. By means of the interpolation algorithm, the delivery points and the cutting points are calculated and combined with the placement trajectory information to yield the complete placement information and a short period. Finally, the fiber placement trajectory method based on the CATIA numerical control technology is tested on an aircraft door placement experiment using the FANUC robot fiber placement equipment. Trajectory end point position error and the trajectory distance error are both controlled within ±0.5 mm.
