Material flow control for bending sheet metal workpiece
摘要
The method uses a friction force sensor (25) detecting the friction force between the workpiece (2) and the lower holder (4) and/or the ring (3), for providing a regulation parameter for a regulation circuit (21) for the device. The regulation circuit uses the received friction force parameter for control of the workpiece holding force (FN) provided by a servo-controlled hydraulic and/or pneumatic cylinder (11).
