In order to meet the requirements of finishing a large number of small mounting surfaces in aircraft assembly manufacturing
a technical scheme of finishing with portable milling machine is proposed. Through the analysis of the precision machining object and the portable machining process
carry out force analysis
dynamics modeling and detailed design of the portable precision milling machine
and carry out the application and comparative analysis. The results show: for the batch manufacturing of small mounting surface of aircraft
in terms of processing efficiency
the portable finishing milling machine improves about 3 times compared with the fixed milling machine
and in terms of processing accuracy
the portable finishing milling machine improves about 5 times compared with the hand grinder.
