Abstract: The influence of the machining regime was experimentally investigated on the output indexes of the diamond grinding the ceramic balls from silicon carbide, such as the rate of the material removal and the rate of changing (decreasing or increasing) the deviation from sphericity of the ball’s surface. To distinguish a particle of these indexes as caused by the actual influence of the machining regime was applied a method of graphical approximation of the time-varying ball’s diameter and deviation from sphericity. The separated particles of the process indexes can vary both as growing and as decreasing depending on the values of the parameters of the machining regime, such as: the discrete feeding of the diamond wheel to the cutting, the time of grinding between feedings of the wheel and the rotation speed of the table with the balls. For further determining the influence of the machining regime was applied a method of a complete factor-type experiment of type 2³, in which the factors of the above parameters were specified. As a result, the most effective way to reduce the deviation from the sphericity of the ball’s surface is to combine these parameters.

Keywords: ceramic balls from silicon carbide, diamond grinding, rate of the material removal, rate of changing the ball’s shape, machining regime, discrete feeding of the diamond wheel to the cutting, time of grinding between feedings of the wheel, rotation speed of the table.
