Abstract (en)
[origin: US2006156779A1] The process comprises combining the operation of gauging by drawing with a stage of crack monitoring and a subsequent operation of mechanically machining the bar through the removal of turnings prior to cutting of the bars in such a way that the calibrated depth for crack detection has a value corresponding to the surface defects in the bar and slightly less than the machining depth in the subsequent stage of machining the bar, with the result that defective bars are automatically eliminated.
