    摘要: A method for controlling a feeding length of a wire is provided. The wire is frictionally engaged with and fed by a driving wheel mounted on a driver. The method comprises steps of: providing a displacement sensing device comprising a driven wheel and a sensor for sensing the number of revolutions of the driven wheel, the driven wheel being frictionally engaged with the wire and configured to be rotated under a frictional engaging force therebetween as the wire is fed; starting the driver to rotate the driving wheel, so that the wire is fed forward and the driven wheel is rotated as the wire is fed; calculating an actual feeding length of the wire based on the product of the number of revolutions of the driven wheel sensed by the sensor and the perimeter of the driven wheel; and controlling the feeding length of the wire based on an error between a predetermined feeding length of the wire and the calculated actual feeding length of the wire with closed loop feedback control until the error becomes zero or within an allowable range.
