The invention relates to the technical field of production
process control, in particular to an MES
system management and control method and
system based on precision mold production and manufacturing, and the method comprises the following steps: obtaining a
measurement point cloud and a theoretical model, calculating
rigid body transformation matrix registration to generate a registration
point cloud, searching a nearest projection point, measuring geometric deviation, and constructing a three-dimensional
deviation vector; and calculating the actual residual material thickness, screening and generating margin insufficient risk points, analyzing a
numerical control code to extract a coordinate instruction, retrieving a nearest risk point, calculating a compensation distance, and adjusting coordinates to generate a self-adaptive finish
machining program. According to the method, the three-dimensional
deviation vector is constructed to represent the entity state, the
risk area is screened in combination with the
machining allowance, the compensation distance is calculated according to the actual residual thickness, and the instruction is dynamically adjusted to generate the self-adaptive program, so that the path is automatically corrected according to the shape of the workpiece, and the overcut risk caused by insufficient allowance is effectively avoided; and accurate matching between the
machining process and the workpiece state is ensured.
