Abstract

In combination of laser etching and numerical control (NC), a localized and precision removal technology for metal coating on engineering plastics was proposed based on numerical control (NC) laser milling. As different positions of the parts require different qualities, a precise processing technology was presented through study and analysis of laser ablation experiments to guarantee the quality of figure edge and corresponding technological parameters were determined. Then, the removal technology for the metal coating with a constant depth was developed by adaptive controlling the laser fluence on the basis of the practical feed speed, by which the allowance within the pattern was removed and the over-ablation problem of the processed materials caused by that the machine feed speed can not reach to a preset value was solved. Finally, a compound three-dimension signal transmission/receiver was taken as an example, the feasibility of the proposed method was verified by processing the part pattern regionally. Processing results show that the compound three-dimension signal transmission/receiver has been processed precisely with the localized and precision removal technology based on numerical control (NC) laser milling. The join of the plane part and the conical part is accurate, the neat micro-strip edge is smooth and almost no heat affected zone. The results meet the requirements of manufacturing the part with high quality and high efficiency.
