Abstract :
Aiming at defect points in CL points generated by CAM, fast CL points pre-processing algorithm was proposed. The defect points were divided into different types including flaw point, S shape and back traverse, the uneven length of the adjacent distance, and each case was identified and corrected by the proposed algorithm. The efficiency and effectiveness of fitting B spine curve from the CL points before and after preprocessing was compared, the MATLAB simulation was preformed to validate this algorithm.
