Summary: | The invention relates to the technical field of metal additive manufacturing, and discloses a regulation and control method and system for layer height of robot electric arc 3D printing. The method comprises the steps that S1, storage and representation are carried out on a three-dimensional model; S2, a current layer in the three-dimensional model is sliced according to the actually-measured height, and path planning is carried out; S3, real-time position information of a robot is acquired, a value is assigned to a register in the robot, and path points are transmitted to the robot for surfacing; S4, a coordinate conversion relation between the robot and a visual sensor is established, and point cloud data of a welding bead is obtained through the visual sensor; and S5, the point cloud data is processed to obtain the actual height of a workpiece, and the actual height is fed back to the process of slicing the three-dimensional model and carrying out path planning in the step S2.
