The invention relates to an intelligent avoiding control method for
machining of a
numerical control flanging machine. Comprising the following steps that before
machining, a correct
machining program is compiled on a human-computer interface according to an actual workpiece drawing or a real object forming process; the
numerical control system analyzes a machining program to obtain data necessary for a position avoiding
algorithm, machining is started, and in a bending forming rectangular coordinate
system, pole coordinate values of a current forming shape are automatically calculated in real time; in the continuous
machining process, the target positions and the action
time sequence of a feeding shaft, a pressing shaft and an edge folding shaft of the edge folding
machine in the next step are correctly adjusted, so that a workpiece and an edge folding
machine die are prevented from interfering and colliding, and meanwhile set process actions are completed. According to the control method and the
numerical control system, the forming shape and related coordinate data of the workpiece can be obtained in real time, the mutual positions of the workpiece, the
machine tool moving part and the mold are adjusted in time through the
process control instruction, and interference and collision of the workpiece, the
machine tool and the mold are correctly avoided.
