Composite material laying pre-compaction control method

The invention discloses a composite material laying and pre-compaction control method, which belongs to the technical field of aviation composite material processing, and comprises the following steps: a, turning on a laser projector, starting to lay a composite material, reading a program of the laser projector through a control module of a data acquisition recorder, and when the program runs to a pre-compaction statement, reading the program by an automatic monitor, the control module closes the laser projector; b, a vacuum acquisition module starts to operate, pre-vacuumizes and performs data acquisition, and when a preset vacuum value is reached, vacuum is kept, and timing is started; c, after timing is finished, the control module turns on the laser projector and positions the corresponding pre-compaction statement to continue running the numerical control machining program downwards; and d, repeatedly and circularly judging the control process a-c until the laying process is finished.
