【Abstract】 Aimed at internal defect ultrasonic inspection for sculptured surface parts, the paper presented a new nearly arc-length approach to path generation. The proposed methodology generates the better distribution inspection point using nearly arc-length based parametric redistribution method. Compared with constant parametric path generation methods, the proposed methodology can generate efficient paths for sculptured surface inspection by reducing the numbers of inspection points, while maintaining inspection demand.A simulation example shows the algorithm is effective and practical. The techniques presented in this paper can be used to improve inspection efficiency of parts and to exploit the current capabilities of inspection system for better inspection efficiency.更多还原
