Process and apparatus for cutting circumferential surface to remove rod

Abstract

Process and apparatus for cutting surface flaws of a material to be machined, including detecting the travelling speed and position of a wire material or a rod-like material in order to set a cut-in quantity to be applied to a cutting tool on the basis of a flaw-depth signal of the signals so detected, operating the advancing and retreating timings of the cutting tool on the basis of the travelling speed signal, the flaw the surface flaw position signal and a tool cut-in angle set value signal that is set in advance, operating simultaneously the advancing and retreating speeds of the cutting tool on the basis of the travelling speed signal and the cut-in angle set value signal and actuating and controlling a tool driving device in accordance with the results of these operations.
