Scientists at South Ural State University have developed the country's first system that prevents defective blanks from accidentally reaching processing machines. Vyacheslav Sedyshev, Associate Professor of the Department of Automation and Control at SUSU, told TASS that the system checks every blank in serial production, rather than being limited to selective control.
The process takes an average of 5 seconds per item. The cylindrical blank is placed in a fixture at a 90-degree angle, after which five induction and ultrasonic sensors read its diameter and length relative to a fixed point. This is dozens of times faster than existing methods. According to the developers' calculations, the system detects up to 30% of defects that previously either went into production or required manual inspection.
The development is intended for the forging and pressing, metallurgical, and machine-building industries. For factories, this means a transition from probabilistic control to guaranteed control: each blank is evaluated objectively and in a matter of seconds, which significantly reduces resource losses and eliminates manual labor in incoming inspection.
