US 4,291,600 A · Process and apparatus for cutting circumferential surface to remove rod surface flaws

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.

A process for controlling cutting of a surface flaw of a wire material or a rod-like material to be machined by a cutting tool which comprises:

feeding the material to be machined;
detecting the travelling speed and the surface flaw position of the material to be machined and transmitting corresponding signals;
setting a depth of cut to be applied to the cutting tool in accordance with a flaw depth signal of the detecting signals;
rotating the cutting tool about the axis of the material to be machined;
feeding the material to be machined longitudinally past the cutting tool;
advancing and retracting the cutting tool so as to cut the material to be machined on the basis of the travelling speed signal, a flaw position signal and a predetermined cut-in angle set value signal
controlling advancing and retracting speeds of the cutting tool on the basis of the travelling speed signal and the predetermined cut-in angle set value;
and
actuating and controlling a tool driving device on the basis of the results of these operations.
