The article presents a model for calculating the current values of the actual radial feed in the internal grinding process controlled in an automatic cycle on a CNC machine. The model establishes the correlation of actual and program feeds with cutting forces, elastic deformation of the technological system, cutting modes, geometrical parameters of the contact area between the wheel and the workpiece, wheel characteristics and other technological parameters and conditions of processing in a wide range of their variation. The obtained model is used for predicting radii changes of the machined hole surface starting from the workpiece to the final size for a given automatic cycle and various technological conditions of the internal grinding operation. The model described in this article is the basis for the development of methodology for multiparameter optimization of grinding cycles in a multidimensional space of control parameters.
