The invention relates to a control method for metal bar sawing adaptive precision blanking, it uses an adaptive bar sawing precision cropping system, which is characterized by the following steps: the level of control of AC servo drive system to realize bar feeding, high precision photoelectric encoder detecting bar feeding amount, at the same time grating the displacement sensor to detect the height at the front end of the bar and the bar on the feeding collet value, vertical AC servo drive system to adjust the bar back height, ensure the high degree of consistency at the front end and the bar material in the feeding chuck at the bar in the process of feeding; automatic adjustment bar cutting Abstract: according to the fixed length L down bar cutting high precision weighing sensor to measure the actual weight of G decreases the weight and the material, set the G down G down the error difference. The invention has the advantages that the bar cross section is perpendicular to the bar material and the cutting accuracy is high, and the automatic, real-time, continuous, on-line and closed-loop self adaptive precise digital control precise blanking is realized.
