Abstract: Targeting at solid of revolution component of composite, presenting the fiber placement path planning algorithm for solid of revolution component. The model of fiber placement path planning based on cubic spline interpolation is founded by using the mathematical model of pipe. The paper first discussed that get the mandrel′s center line equation by cubic spline interpolation, then found the mandrel′s parametric suface equation, and at last proposed a novel path generation algorithm which is appropriate for the solid of revolution component. The path generated by this algorithm is satisfy the process requirements and engineering need in practice after example verification by MATLAB.

Key words: composite material, fiber placement, path planning, cubic spline interpolation
