In this paper, the cutting force in plasma arc-assisted turning of ZGMn13 was studied by experimental analysis. The laws of influence of various technical para-meters, such as V, f, ap and I, on cutting force have been found. And the mechanism of these has also been discussed. The empirical formula of main cutting force in plasma arc-assisted turning of ZGMn13 was cstablished by means of regressive analysis. The general principles for selecting the para-meters, such as La, LAT, the heating position were suggested....
