The feed rate and the grinding ratio for abrasive cut-off process of S 50 C steel were analyzed 100 times in terms of different combination of grinding conditions. The analysis included the length of cut and the load. The tests were carried out at the wheel speed of 4 800 m/min in order to investigate the optimal abrasive cut-off system. Autoregressive-moving average model, ARMA(2, 1) is developed to represent the stochastic process of the feed rate and the grinding ratio. The feed rate and the grinding ratio are optimum when the pressure between the wheel and the workpiece is 6.67 N/mm². Best abrasive cut-off performance by the constant load system is obtained by using the length of cut of 15 mm and the load of 300 N with the height of workpiece of 22 mm at the wheel speed of 4 800 m/min.
