The invention discloses a feedback adjustment
system, a
laser additive manufacturing device and a feedback adjustment method.The feedback adjustment
system comprises a multi-source collection module, a
data processing module, a defect recognition module, a
process control module and an adjustment feedback module, and the multi-source collection module is arranged corresponding to an execution component of the
laser additive manufacturing device; the multi-source acquisition module can acquire
molten pool state information and
powder transmission information in
laser additive manufacturing, the
molten pool state information and the
powder transmission information are processed through the
data processing module, the defect recognition module recognizes the category, the position and the defect evolution trend of defects, and the
process control module adjusts process parameters in
laser additive manufacturing according to the category and the position of the defects. And the adjustment feedback module sends the adjusted technological parameters to the execution part, the multi-source acquisition module continuously acquires information in the
machining process, and the feedback adjustment
system continuously feeds back and adjusts the technological parameters of the execution part according to the acquired information so as to continuously monitor and form dynamic adjustment on defects, so that detection and closed-
loop control on the defects are realized.
