| Abstract: | Based on the study of the physical process of the las er milling and the analysis of bounce-back pressure of the spout matters a model for discharging redundant matter was set up. The status of the spout of melt was observed, and the course of the spouting was typed by photography video with hi gh-speed to prove the correctness of the model for laser milling. The influence of steam bounce-back pressure and assistant gas on fused substance spout speed was studied. The influential mechanism of assistant gas on laser milling speed and the milling quality was analyzed. |
